A little more $ now = $$$ later
Good bang for your buck. Spend $15 more now and save in the long run. Reason is with Strike's kit, you get a better hammer and a middle ground for trigger LB pull also a bigger bolt & mag release with the bonus of big hinge pins. The biggest difference in money saving is with the trigger and hammer that is where you will see the savings add up. Fitment was great, smooth, and went… read more in without a hitch.
One of the best lpk's on the market
Great value, high quality. One of my favorite kits on the market
Great product!
Works great fit and finish was great will buy again on my next build
So easy to order
Vary easy to ordeo
Strike Industries does it again
Whether you're building something, or you made an oopsie, this kit is well worth to have!
Strike enhanced lpk.
Love these kits. This will be the 3rd consecutive build I've used it for.
Worth it.
Even from the smallest details of the detents, this kit is quality. Polished the trigger because that's what I do regardless, but took alot less effort than a standard milspec. Great kit for the money.
My First Choice in Parts Kits
I install these on every build. Would be nice if they came with labels and instructions, but these are easily found online.
Perfect fit
Everything fit perfect and was nicely built.
AR-15 lower parts kit
Great customer service and product descriptions
Everything Include
All parts needed for a mil spec build. Fast shipping great service.
Parts fit perfect, very good kit
I had no issues at all, everything fit the way it should. I really like the slightly extended take down pins and ambidextrous safety. The trigger pull is very smooth and consistent.
Great quility and price
Big fan of this lower kit, is such a great deal if building your lower and plan on installing an ambi safety, enhanced bolt catch and mag release. This kit will save you money and time buying and installing them on later. Great kit, will be using one on next build as well.
Solid
Works great no issues
Great kit
This is my third kit great kit
Good parts kit w/FCG
Honestly I didn’t expect much better than milspec with this but the trigger actually feels really good for the money! Sure you can spend more and get better but for a sub 1k build I would definitely buy this kit again!
Good parts kit
I used everything with the exception of the included trigger spring. It was a little stiff for my likings. Everything else was perfect. Loved the enhanced take down pins and bolt lock.
Thumbs up
Strike industries always comes through with good quality and looks for the money.
Perfect for new build
used to complete a Strike Themed AR build
Excellent value w several enhanced parts
You get A LOT of enhanced parts for an excellent value. This is even a better deal when you get a sale or a coupon.
Nice set!
Everything there to build the lower receiver! I like that pins holding take-down pins have a needle edge to go into the spring.
My go-to LPK
This is my favorite lower parts kit. The trigger is smooth with very little creep, and the bolt release lever is more ergonomic than normal milspec.
Strike Industries AR15 Enhanced
Awesome, fit perfectly.
Great service!
Pieces fit well and go together as they should. Their customer service is top notch. I had a question and they personally respond in a timely manner. Will definitely order from them again.
Strike industries review
The product came in individual packages for each section of firearm and had exact description of what was contained. Very good price as well.
Strikes again
This lower parts kit is awesome!!! Typical strike….amazing quality.
Great value
Unlike other lower receiver parts kits I have purchased, everything fits as it should. I have had two others where the J-spring protruded into the hammer that the pin could not go through. IF I had purchased this kit from AR.15 Discounts, they would have replaced it. Not so with the supplier I used. AR15 Discounts has one of the best customer service departments I have ever had… read more the pleasure of dealing with.
Great!!!
Very nice, Looks awesome. works great, better that milspec. nice price.
Great item!
Amazing! Fast shipping! Great item!
Good
Thanks is good experience
Strike Industries AR-15 Enhanced Lower Receiver Parts Kit with Trigger, Hammer & Disconnect for .223/5.56
Perfect kit to get my lower put together. Showed up early as well.
SI enhanced lower kit
Kit was really great. Only gripe is the Ambi safety is sharp on my trigger finger hand. Probably gonna put a different one on
Strike industry lower parts
They fit and function great. Will buy again.
Good kit except for one spring
The bolt catch/release spring did not fit in multiple lowers, causing the catch itself to not function properly. This kit should also come with the ambi mag release.
Great value. Nice Trigger.
Great price and I like the ergonomics. The trigger is also very smooth.
The best
Awesome exactly what i wanted
Best Lower Kit on the Market
I love this kit. Will always use Strike Industries.
Good LPKs!
Part kit was complete and fit well. The only thing missing was a trigger guard to complete your build.
Fantastic
My third Strike enhanced LPK. Work perfectly, and much better than standard mil-spec kits. Certain to buy more.
Solid parts
All the pieces were there and everything fit snuggly on my aero lower.
Good parts at a good price.
Perfect fit and finish.
Great part kit overall
I think the parts get is great overall. The only bad thing I have to say is whatever size the little screws are that go into the ambidextrous safety selector need to be a more common size, or include a cheap allen wrench in the current size. Other than that, I feel like it's a very solid parts kit. I used it for a customer's to build and he was very happy with it.
Prompt Trouble Free shopping!
The Strike lower receiver parts kit is full of little pieces that help you run your gun more efficiently. The fire control group is really good. It would pass for a much expensive kit. Great buy!
Parts kkt
Im happy with strike parts they get a bad reputation for a reason unknown. Aero precision quality at least.
So far so good.
Good kit and easy to install. I like the look as it isn’t completely stock look.
Mostly Great
Overall I am happy with the product parts kit. One thing that’s not included in the kit is a trigger guard. Which I was aware of placing the order. Also some of the parts that had the SI logo etched in were smudged and two pins for the trigger were a hair small.
Solid LPK
Worth the extra $ over a mill speck LPK for the bolt catch, pins and ambi safety. Trigger is nice as well
Great Produced
Woks and functions as expected. Would recommend and purchase again.
One of the best!
This is one of the best build kits available!
Good quality and price
This lpk is good quality for a good price. The only enhancements I see are on the bolt catch and detent/takedown pins, but they are good enhancements.
Very nice
Everything in it is very nice and enhanced. Trigger is very smooth & about 4.75 lbs. Very impressed with this lower parts kit. Definitely will buy again.
Great parts
The parts were perfect and everything fit like it should.
Good fit & smooth operation!
Used the kit in an Anderson lower and everything went together well. Loved the short throw on the safety and the trigger action was perfect.
Decent item
Great, good quality and came quick
SI AR15
Nice smooth ambidextrous selector & the trigger breaks crisp at about 4lbs.
Awesome
Strike industries makes kick butt parts.
Lower receiver parts kit-Strike Industries
Great kit. Nice trigger also. Measured with electronic gauge and trigger pull came in at about 4.75 lbs with a good ,crisp break. Highly recommend this kit from AR15DISCOUNTS
Strike Enhanced LPK
Overall a good LPK. I did have to grind a little off the flat edge of the pivot pin to fit it with an Anderson lower. Good kit though with a nicer than expected FCG.
Quality Service
While most companies are struggling to keep up during these unprecedented times AR15Discounts.com has shown quality service, expedited shipping and delivered a quality product. I've used sites for purchases and had to wait over two months to be left unsatisfied without a complete order fullfillment.
Bad ass!!!
This was the first time I’ve used a Strike Industries lower build kit, and wow!!! The subtle details such as the black detents and custom take down pins make this kit feel like it’s easily worth twice what you pay. It’s now the standard lower kit for all of my company’s rifles!!!
Solid Product
Great fit, solid finish, and crisp function. Trigger is darn good for a standard trigger. Overall great product!
Strike lower parts
Strike has put together a great lower parts kit that is reasonably priced for what you get, I have used many of them in builds and they are simply to speck, the trigger group is much better than regular mil-spec especially when coupled with lower power spring set. AR15DISCOUNTS have been great to deal with and I have ordered a lot of product and will continue to do so.
Lower build kit
Great build kit for the price
Great products as always
This lpk will be going in my Aero Precision lower on a build for my son. Great products and great service!
Lower parts
This is a great kit. This is going to be my go to kit for my lower builds. AR-15 Discounts is awesome. Great Service.
Good price
Haven’t put it together yet saving it for when I have time
Excellent product excellent company
I couldn’t be more happy A.R. 15 discount at one of the best companies I’ve ever done done
Great lower parts kit
When I got this kit it thought it was pretty nice and it was easy to install. Haven't got to test it yet but seems to function perfectly. But I realized how good this kit was when I did my next build and used the kit that came with that build. The difference was huge, so huge that I'm waiting for this to be in stock so I can replace the terrible second kit I got with my build. This… read more will probably be my go to from now on if it comes back in stock.
Great price
Not yet used but just about all you need for a good build.
Quality
Appears to be of better quality than most lower end kits available. I like the shape of the detents... they basically have a seat for the spring unlike others.
Worth the money.
Overall, very nice fit and finish. The trigger is crisp without a lot of creep. It has a short throw, ambidextrous safety, which I really like. The only issue I encountered was with the enhanced bolt catch. I installed the kit on a Polymer80 lower but the bolt catch would not function due to a heavy polymer ridge that is molded at the bottom section of the bolt catch area. The polymer… read more could be filed down to make it fit but I chose to stick with a stock catch and save this one for another build. Happy customer.
Not really enhanced
strike Industries labels this as an Enhanced Lower Parts kit but it lacks a trigger guard and extended takedown and detent pins so I am failing to see where the enhancements are? That’s why I only gave this a 3 star review on AR15Discounts which is the same as I will give it on the Strike Industries website. They should call it a semi enhanced lower parts kit with no trigger guard.… read more
Strike Industries LPK
Fantastic LPK! I have built a bunch of ARs recently and was trying out LPKs. The SI LPK to me was the best bang for you buck compared to others I liked such as Seekins and Armaspec. All parts have a unique design and stick out in a good way. The safety selector is short throw and is very nice to toggle. I really like the bolt release as well. Nice feel on all the parts! Great product!
Perfect for my build
I used this in my 300blk pistol. Works great!
Awesome Kit
Excellent as always
Strike Industries Lower Parts Kit w/ FCG
My experience is only with the PSA EPT so it's very shallow. It feels as crisp as the PSA EPT with a slight lighter pull. Overall I can't really tell the difference between a 4-5 lb trigger pull vs a 7-8 lb trigger pull. The enhanced parts are nice and everything works. Happy with the purchase.
Strike industries AR-15
Great product. Very easy to assemble.
2nd Time using this kit
Simple to install and an added value over the mil spec kits. Extended mag release, ambi-short throw safety selector and reduced power trigger. Love it.
Good product
Great product. Well made and easy to install. The detent pins are great and easier than older models to install.
Strike industries lower enhanced part kit.
Amazing, love it.
Perfect
Second one of these kits and they are consistantly good quality. trigger pull right out of the box feels nice. Not award winning but very very good for the money.
Very good set
I love the bolt catch and the take down pins i recommend this product
Great buy
Easy installation into my Aero lower. Love the enhanced features. Planning on getting another for my other AR.
Quality parts!
Love the LPK so far Trigger is crisp the parts are quality and not cheap
So far so good
Everything went together fine, quality was on par with any other kit I’ve used
Amazing parts kit
Strike Industries makes some of the best Gucci gear on the market and this parts kit is an example of it.
Great!
I love this company! Affordable ar parts. Havent had any failures or defects!
Excellent Service/Excellent Parts
Building my first AR, and everything on this site will give you the best information and parts needed to successfully complete your build! Great service and quick shipping although a nationwide pandemic! Great place to find what you need! Definitely recommend it!
Strike Industries Enhanced LPK
This lower parts kit is very well made and the fit and finish is excellent! The trigger-pull is very crisp and smooth! Really gives the AR a nice custom look! Great service from ar15discounts.com!
Great product
This is now my second time buying the strike industries enhanced lpk. When I do another build it will be the first one I look into and get
Great products at great prices!
Strike Industries make great parts at reasonable prices, and never have trouble with anything they make.
SI lower parts kit
Great kit trigger feels great and everything looks awesome on my lower ar15discounts you guys are amazing super helpful and very fast shipping!!!
Forever customer
Love the quality and price for this kit was cheaper than most factory kits but had better parts
Strike lower parts kit
With online videos I only made one mistake and it was my own. The parts kit was complete, well packaged and easy to install for first time builder. A really good value for the price. I will buy one as a spares kit.
Awesome Product!
I used this parts kit for my 7.5” pistol build and I love it! The pins are super easy to pop in and out. The trigger is pretty good for a 60$ parts kit. The mag release and bolt catch are nice and big which makes using the rifle quick. I used along with many other strike industries products and I am very pleased with the company’
Amazing product!
They are very clean and sleek and are just what I need. They feel very rugged and of the highest quality, and arrived sooner then I expected
Parts
Great.................
Great product! Greater price!
Everything came together with ease. Trigger is butter!
Top quality
Absolutly love this product the design of the takedown pins is really slick with a nice polished trigger to top it off a wonderful crisp break and reset will absolutly use in my next build
Amazing
Everything fit together perfectly and looks great. Crisp trigger and the 60 degree safety throw is a very positive flick. Had a minor issue with mag release getting hit on the bolt release when trying to screw it in. Just put the mag release in before the bolt release and you’ll be fine.
