The Cobra Stock MK2 features our own Patented locking system, battery storage compartments and an oversized cheek rest. The Cobra MK2 is easy to install and remove on the any Mil-Spec buffer tube. The butt-pad profile is angled to accommodate plate carriers and the aggressive texturing will ensure minimal movement when manipulating the rifle under stress. Multiple sling points and lightweight snag-free construction the Cobra fits into most builds with ease. For your safety, Trinity Force recommends this part be installed by a competent, qualified gunsmith/installer with an understanding of the weapon platform that the part is being installed on. Always make sure the firearm is unloaded and pointed in a safe direction when working. The AR Receiver Extension Kit is constructed from aircraft grade aluminum with rolled threading. The buffer tube has been hard coat anodized for maximum corrosion and wear resistance. A standard buffer spring and 3oz carbine buffer are included as well as a castle nut and lower receiver end plate. This assembly kit will fit on all Mil-Spec AR-15 lower receivers.

Trinity Force MK2 stock&buffer tube kit
Overall very happy with kit works great. With stock collapsed or extend no movement in stock. I will use it collapsed for close quarters on 300 Blackout great weapon!
Trinity Force Cobra MK2
I understand it’s a budget stock but it’s looseness on the buffer tube is totally unacceptable. I would imagine if someone claiming to be “mil-spec” it ought not be hard to mold or machine to the common/standard known dimension. I wouldn’t recommend buying this, I will be reaching out to AR15Discounts.com for a return shipping label or something for replacement. It’s… read more unfortunate because it looks good and the material appears to be more than adequate.
Missing parts
Shipping was great got it quick but missing the plugs for the battery compartments and also missing an Allen head screw for the release on the stock to be able to adjust to different positions
Better than fixed A2 buttstock
Comfortable with or without jacket. Easy for my wife to shoot my AR47.
Trinity Force Cobra stock
I love this stock. I’ve ordered two of them. I like them better than MagPul and they are cheaper
Excellent stock
I’ve always used Magpul but I thought I’d try this one and was I pleasantly surprised. I like it better than the ones I’d always used. Fit great and shoots great. I’ll. Up more for my next build.
Buffer tube
easy install, great quality
Awesome product
Awesome product fit perfectly will buy again.
Very Solid Stock
This stock kit was a great price. Its very solid and looks great, doesn't feel cheap like some stocks I have used in this price range. Ar-15 discounts is always great with shipping and customer service.
Trinity Force Cobra MK2 Mil Spec Stock & Buffer Kit
It's a complete back end kit. Has everything you need to get your rifle. The only issues I noticed is that it sticks when extending the stock which could be me and its shiny. Nobody likes shiny but I fixed it.
Love it
I've used 4-5 of these and I'm very happy with how they feel.
Quality Product
It does the job - nothing special but if on a budget and need respectable this will work
Great products for the bang
Always great fast shipping great products
M4 Stock
As usual, great pricing, super fast shipping! Easy to install and comfortable. You can't go wrong with stock! I've bought several and will continue to buy more!
Well made stock!! I am loving it so far.
Easy to install, excellent ergonomics.
The worst stock
This stock is worthless. I have a gen 1 cobra stock and love it. It has a really stiff spring and tight fit to the tube with a great rubberized cheek rest and long LOP compared to most stocks. I also have the alpha, which was basically the same stock without the cheek rest. This new stock is completely plastic and doesn't fit the tube at all and makes a loud click because it's just… read more sloppy. ABSOLUTELY DO NOT BUY THIS GEN 2 STOCK!!! I only gave it a 1 star because zero wasn't an option.
Good quality, inexpensive
Overall the quality is pretty good on this kit. I would recommend this to anyone that needs to finish a build, or replace worn out parts. The only complaint I have is that the battery holders in the stock are for AA or AAA size batteries. They will not fit a 18650 battery. To me, it's not a big deal so I still gave it 5 stars.
Good stock kit
Feels positive on all positions and very little wobble
Buy
Excellent quality and easy install
Stock purchase
My experience was great. Ordered my stuff and got it quick, better value than what I was expecting
Cobra MK2 Stock and buffer
Very well made and the stock is easy to adjust.
Works great
The intire kit is great looks great easy-to-use and extra storage is really nice
Trinity Force Cobra MK2 Mil Spec Stock & Buffer Kit - Black
Great fit and feels comfortable. Downside is the spring in the lever to adjust it on the buffer tube is stuck. So it requires a lot of force to free it to adjust almost to the point where it feels like it could break.
Nice product, great price
It's actually quite solid and has a great fit on the receiver. Looking forward to running it
Stock kit
The Trinity Force stock kit was a great addition to my rifle. Parts fit well and the stock is secure. I have used these on a couple of other builds and have had no issues. Item was shipped in a timely manner and the price was great compared to other sites. Definitely will purchase again.
Grey for the price
Great for the price. Just a little on the heavy side
Force Cobra MK2
Nice Stock and Buffer tube kit at a great price
One of the very best deals you’ll find .
Best deal with all you need to throw yourself a stock onto a carbine and be in the game . And these days that’s big deal . I’ve been back to this shop I think 4 times now and they ship super quick . Also there customer service is on point . Really get it done for you . I messed up my address on my first order and they straightened it out for me . They saw my address was different… read more than on my card so they hit me up . AR15 Discounts : one of my very first go to’s . I’m sure I’ll be here again . Subscribe to their email list you will be glad you did
Haven’t installed it on anything yet, but after receiving the 1st stock I purchased 2 more as it looks & feels quality. Pleased with the product
Trinity stock and buffer kit
Great product great price
Tim
Great product, fast shipping !
Excellent. Quantity and affordable
Affordable quality stock. Nice and tight feel. Great all around.
AR 15 stock kit
This is a great stock kit for any AR build. I have bought 3 of these
Nice package
Everything you need
Really Nice
The feel of the stock is great. Everything is nice and tight. I have not shot with it yet. I will be putting this on a .223 Wylde upper soon. I hope it preforms like it feels.
Trying a new business.
Most professional and quick service.
Trinity stock
Very nice, just as described
Bought for 9mm carbine and fit matched great.
will be using them in the future. great product.
Better than expected.
This stock was definitely better than I expected. Very comfortable cheek rest built in. Installs easily and adjusts easily. I ended up buying two more.
Smooth
I have 3 of this. They just feel and operate very well.
Its ok
Not very solid. It works, but I hate loose butt stocks, for an inexpensive build it will work.
Spikes build
Very nice dealing with this place get my orders fast and good prices.
Trinity stock is amazing!
Can’t beat the price for the quality of this piece. Really like it was easy to install would recommend to anyone looking for a new stock.
Love Love Love TFT!!
This is my 4th TFT stock I have bought, also own one of their optics. I have zero complaints about any of their products and LOVE the price of this kit. My LGS sells the buffer tube for the same cost of this entire kit! Cheaper gun parts means more gun parts!!!
Sweeeeetttt
Fit perfectly, looks gosh darn good
Great for AR build or upgrade at fantastic price
delivery was fast and on sight feedback was/ is spot on. easy and simple to install.
Great stock kit
Great stock. nice cheek weld, good quality, and a hand written thank you on the invoice. I'll be back here for more awesome things.
Cobra Stock
I love the way this cobra stock looks on my build
Trinity force stocks
Excellent product for the price! Customer service/shipping was terrific. Enjoyable to order from this company.
Great stock!
Love this stock and it also looks good!
Have not used it yet
Have not used it yet but seems to be a great addition to the gun.
Great purchase.
Easy to purchase, great price, and fast shipping. Great product and it was priced right.
Excellent product and shipping
The build went very well, very Happy with the quality of the product and the shipping time. Received on the 3rd day after order. Will definitely be ordering from you guys again. Thank you AR15discounts.com!
Trinity Force
Great finish on the products and fit perfectly on my build.
Good stocks
No complaints whatever. Bought one, then two more after trying it (two built, one building now). I wanted cheek support with comfort for all day shooting. The flared out stock is what I wanted. Rubber cover is stiff but better than composite. The release trigger was a big seller in that I don't want to search inside an enclosed guard in the event things get spotty (law enforcement).… read more Some say it's a stiff movement. It is somewhat. Just takes getting used to. Sturdy material. I did change out the end plate to an ambi sling hook and a PSA buffer (buffer flats are larger on the Trinity than PSA). A major brand has a similar for twice the price. Buy again? Already have.
Trinity stock..
This is a great stock for the price..
Great stock for a budget price!
This stock is great. Very well built and has all the features of a high end expensive stock. Trinity force did A+ with this one! Also super fast and reliable shipping from ar15discounts.
Ar15 stock
it was excellent went together good
Mint
Really mint for my ar15 450 bushmaster feels good on my shoulder i will tell all my friends about this
New AR Stock
I am very pleased with my new Trinity Force Stock. The price was excellent and the shipping time was minimal. I am ready to install it and all I need is a few minutes to myself. I will purchase more of these for my future builds.
Fantastic stock
This is one of the best stocks I've ever used. Comfortable and the wide cheek weld is great.
Great quality and quick shipping
Like it a lot. Looks great and adds better character than the factory stock. Real comfortable on the cheek as well
Gun stock
It was easy and great. Part was affordable and cheaper than anyone else
Appears to be Quality
All the pieces lined up and installed with out issue. the buttstock and buffer tube feel solid. I thought the buffer spring and buffer felt a bit flimsy, but functioned well during the test fire. I still may put a heavier spring and buffer in. Thats the only reason 4 stars.
Really nice stock
This is a great stock at an affordable price, I have these on a couple of different rifle builds. I really like the overmolded rubber on the cheek rest. And I recommend these products to a lot of my friends and family
Amazing stock!
This is a great stock.for the money you can't beat the quality has a really nice rubberized cheek well as well as QD attachment holes built in. For the price you can't beat the quality.
Fast and Easy
Great product, fast and easy service. Will definitely be using them again. About to go look right now actually.
Trinity Force Cobra Mil Spec Stock and Buffer Kit
Excellent kit. Worked perfect on my MechTech 10mm.
Good product for the price
Shipping was fast
Stock & buffer kit.
Excellent prices!!!
Great budget stock
Picked up 2 of these when they were on sale. Wanted to replace the loose fitting milspec stock on my Colt AR22 and figured the rest of the kit would be spares. (decided to grab another just in case) Not much to say about the the stock, but it does what it is supposed to do. Fits on the buffer tube nice and snug, no wobble. Adjuster works as it should, looks good and has a nice wide… read more cheek piece. Overall very pleased with it. The only negative I can think of could be the weight, if that matters to you. It seems pretty hefty compared to some of my other stocks. (Magpul, Rogers Super Stock, Strike Ind, Milspec)
Great value
Great value and quality for the money. I’d buy one again
Good product, good price,fast shipping
Good product, good price,fast shipping.
Happy builder.
Good quality products that fit as advertised. Delivery was very quick and hassle free. Really happy with my purchase from ar15discounts.com. Definitely will purchase parts in the future to complete my build.
Great item
Great item for a great price!!!
Trinity Force Cobra Stock & Buffer Kit
Easy to install and looks great overall. The check rest is comfortable while making adjustments for the slide.
Trinity Stock and buffer
Great quality and awesome price.
Great Design.
The stock kit fits flawlessly, functions well and makes the rifles appearance very tactical.
Good stock
I'd buy it again. In fact, I may for my wife's rifle. I wanted a cheek support and this offered the support as well as a rubber cover for it. The adjustment trigger is flush, which is another detail I sought. The buffer spring has more tensile strength than the stock (PSA) spring that came with my build. However, while stock is tight on the buffer rod, the buffer bolt is rather… read more loose. I'll probably swap back to the PSA buffer bolt as it's tighter. I sought a different buttstock because the standard PSA buttstock that came with my build kit was loose, felt like a cheap toy. This Trinity Force Cobra has nearly, feels professional, all I asked for (maybe a tool/scope battery storage unit in the cheek supports?) that I wanted at half the price of others that offered similar but even less options. For the price? Yeah, I'll buy this all day long. New Trinity Force fan.
I’m buying two more
Great product. I probably am buying two more of them. Love the larger cushy cheek weld and buttstock is comfortable.
Fast shipping great product
Very happy with service
Great product at an even greater price
Fantastic experience will shop again and again
Great buy and and very happy with my purchase
Fast shipping and great quality
Trinity Force Cobra stock and buffer kit.
I have now built two rifles using the Trinity Force Cobra stocks and buffer kits. There was a slight issue with one binding when extended, but only a very small amount of protruding plastic had to be removed from the inner and upper part of the stock where some of the original cast protruded. The stock now extends effortlessly. Both do tend to rattle a bit, but not seriously and… read more probably something that happens with most on the market. Fast shipping and good packaging.
Comfortable! Great Value
Great buttstock Kit. Has everything you need. It’s very comfortable shooting for a little over an hour.
A+ purchase
For the price it's a great deal! Has a great cheek rest and butt pad helps take up felt recoil.
Great value, quality product
Very good. Stock is solid, has a good feel to it. I would buy it again.I started out just needing a buffer tube, but liked the stock so well I put it on my gun.
I love mine.
Great for the price. Rubber is firm but comfortable on the face.
Outstanding as usual!
Fit and finish was absolutely perfect, tolerances were incredible. No wiggle no shake on the stock, customer service is phenomenal as usual
Best value in stocks
Excellent. Easy to install, good quality, outstanding price. Solid buttstock for ARs.
Very Comfortable
This stock feels so good against my cheek. AR15DISCOUNTS are super to do business with!
Trinity Force Cobra
Wasn't sure about this butt stock kit, but the price was right. When it arrived, I did find the stock to be difficult to slide on the tube, but quickly found the problem was with a bit of overrun plastic from the top cheek piece. A few passes with some sand paper on a stick solved the problem. It all mount well and easily.
Trinity kit
Great kit for the price. Couldn't figure out how to remove the butt stock from the buffer tube but that's just me being dumb Honestly the stock is as good as my b5 sopmod
Good stuff.
Small issue with charging handle coming in contact with the top rubberized cheek rest.. I also missed that it was adjustable somehow but I just epoxied it into place.. lol.
Awesome
Great buy!!
Stock
This is a comfortable stock great cheek rest and will buy another one for my next build
Awesome product, at a great price!
So far, so good. I purchased trinity force cobra mil spec stock and buffer tube because of the price mainly. I built a rifle for deer hunting, and didn’t want to spend a ton of money on something that will most likely get banged up. After receiving it, I put it on my lower receiver and I was not disappointed! I will definitely be buying another one for my next build!
Great High Value Budget Stock
I have tried various stocks on previous builds and have found that this is the choice I always return too. Ergonomics are great and you cant beat the value you get for the price.
