BEST PLACE FOR PARTS!!!
YOU'RE MY GO TO WHEN I NEED PARTS FOR MY TOYS!!! AWESOME AS ALWAYS!!!
Great People, Great Parts, Great Prices, Great Service!
I bought 2 of these lower build kits. Perfect fit and finish. One kit had a wrong spring but they made it good fast no questions asked! (And no, I didn't loose the spring.)
Nice price for a nice kit
Nice parts at a good budget builder friendly price. And the shipping was fast too!
Decent kit for the money
Overall the kit isn't too bad. The butt stock is not my favorite and leaves a lot to be desired.
New AR
Everything went together flawlessly.
Good kit.
It got the job done.
Great Choice
This kit works as good as any factory parts I've had
Great value and quality
Outstanding all parts fit perfectly and no issues with the build of Anderson lower
It works
smooth is the best way the parts came together in the build.
Outstanding product
No problems in installation and worked just fine.
Good utility build kit at a great price
Good quality parts for a utility build. Not trying to build a "match" grade weapon, just a good reliable utility AR, this kit works great. No issues.
Amazing kit
This kit was easy to install. Also everything was in its own bag so it was easy to organize. Nothing felt cheap at all.

Good quality fast shipping
Ar parts kit
Would buy again easy to install
Mil spec lower build
Very nice product and awesome experience!
Mil spec lower kit review
found magazine latch arm poor fit in recess of two different lowers. Required machining of outer surfaces for proper fit. Pistol grip screw too long. Bottomed out in screw hole and required spacer for proper fit.
Mill spec lower kit
Awesome went together no problem
Good value - all parts fit
Time will tell if they hold up but overall a good deal at sale price in current market.
Nice basic build kit.
I didn't have any problems with the kit at all. The pieces fit perfectly, all the pieces were accounted for. The build went exactly as planned. The price was better than buying the parts separately.
Great Value
Good quality for the price
Valuable at a time like this
Well I have examined the parts but not used them. The buffer tube assembly appears to be higher quality than the normal DPMS kits. Stock an pistol grip are what is expected. I like made in the USA. The parts look as good or better than the standard CMMG packages. So in general its a good deal.
Everything fit and worked great.
Everything went together great.
Nice quality
This is a really nice quality lower parts kit. Although the buffer assembly and stock leave a little to be desired the parts are really nice. I like the aluminum trigger guard and I can tell the trigger group is made from quality metal and precision machined. Plays really nicely with 80% lowers.
Basic build
All the parts good quality for a entry level basic build. No issues.
Excellent product
Fit and finish perfect went together with out a problem
Good parts great price
Excellent. All parts fit perfect in my PSA lower.
Good kit for the price
I was mainly doing a budget build and for what this included I couldn’t have done better elsewhere!
Great Build!
This is the first time I've decided to build an AR and chose this lower parts kit to finish my lower. The parts for this kit are well made and fit together perfectly. I really enjoyed putting the lower together as it was very educational. I am an architect by trade and noticed one thing I liked was the trigger assembly as the connections were clean and smooth. I ordered a trigger… read more reduction spring set that made the trigger pull even more comfortable. Overall, it took me 20 min. to put this lower kit into the lower and loved the experience! Almost done with my build, but its coming along! Great Parts Kit!
AR15 lower
Great nice looking and happy with product
Great parts kit for price!
Ihave used several of these and they are great part kits.
Great deal for the budget minded.
I was expecting cheap or poor quality, very surprised buy the parts. I would buy again
Great product for a good price.

Parts kit
Great no problems works great!!!
Super great & fast
Basics mill spec lower parts, incredibly fast shipping, great quality for mil spec. Came with a personalized shipping label. I’ll order more in the future.
Awesome Lower parts kit
Great, everything went together without any problems. Looks just like my old issue weapon.
My lower build
Overall experience with it was great everything works properly and fits in place.
Not a total surprise
the butt stock was not made well, and doesn't fit or slide nicely over the buffer tube. It appears that the mold it was created in may have deformed. This package was relatively cheap for what it contains, so I'm not upset.
Typical MilSpec equip
Same as any other company, just a might bit cheaper, it was a very good deal.
AR lower kit
You can't beat the price, quality is solid, everything went together without issue. I would purchase this again without hesitation.
AR lower build kit
Great Products and fast shipping
Prefect kit
Awesome, product was exactly what I needed to finish off the lower.
AR lower
It’s all there. Looks good assembled.
Good Kit, Good Price
This is my 2nd lower kit from AR15Discount. It may not be the best you can buy but, it is the best you can buy for the price and it works quite well. All the parts seem to be well made and it fits and works just fine. You really can't beat the price.
Awesome parts kit !
Easy install, all the parts worked well and went in easy! Functions great already put them to work on the range!
Build kit
It fit like a glove. Every part was there, and it works great
Just what I needed
Love it. Fast shipping, great deal , easy ordering
Haven’t received it yet for review!
I received my last order today but haven’t seen the one I ordered back on Order #AD341046 (February 13, 2021) so when I do get it I will review it. Thanks and have a great day!
Fun build
These build kits are fun! Went together nicely all parts and pieces work as intended, have bought and built 2 now.
Works as expected
Everything went together perfectly.
Great parts
Great value and this is my 4th buy.
Exceptional Value
Bought these to go with TA polymer 80% lowers. Haven't built them yet, but seems to be decent quality for the price. My primary objective is to get a functioning AR platform carbine for under $400. If that happens, I'm happy.
Good Product
Shipping was fast, assembly was easy, besides the bolt catch roll pin. Would give 5 stars but it was missing the trigger guard roll pin.
Better stock up
Great! Pew Pew life!!!!!!!!
Works well - cycled 500 rounds no problem first time out!!!
Fast shipping even with all the pandemic and mother nature not wanting me to have this.....customer service was awesome by the way too!!!
Solid lower parts kit
Overall the kit is nice and the parts fit well. The only down side the the trinity force buffer tube, buffer and spring. They are lacking quality but it works so there is that.
Great Build Kit and Unbeatable Price!
This build kit installed easily and worked perfectly. Completely exceeded my expectations.
MIL SPEC BUILD KIT, GOOD FIREING PIN.
OUTSTANDING ITEMS, GREAT SHIPPING.
DIscount mil spec lower build kit
I have purchased 3 and will buy a few more more to finish up a few more lowers. These are solid kits for teaching classes. The fit is as expected the triggers are heavy but crisp. Very safe and fun with no worries to purchase another
Great deal nice kit
I have bought several of these and they are great parts kit. You get everything needed for your lower for one low price!
Best kit I’ve used
I’ve bought kits from many different manufacturers, with varying degrees of satisfaction. This kit wins hands down. Every part was there, no missing detents or dead spring. Everything packaged nice and wrapped to prevent jostling and ‘scuffing’ during transit. I finished up my lower, and promptly ordered a second kit as a spare.
Quality Parts/Fast Shipping
Great products that fit perfectly!
Money saver
Good milspec kit functions great
Great parts kit!
Fast shipping as always! Good parts for a good budget build!
Ar stock kit
Good product will be ordering more
Good stuff for the price
8.5 out of 10 fast shipping
Discount is the key word
Everything fit where it was supposed to and functions but this truly is a discount kit. I wouldn’t use this in a build that I was trusting my life too. Magazine release is a little long and pops out and won’t catch new magazine if your not paying attention and the take down and pivot pins are very stiff. If you still want it after knowing these facts then you will be happy with… read more this kit for the price.
Great for the price
Everything looks great and fit perfectly
Nice for the Price!
Most parts are good and accurate, but a few needed a small amount of smoothing.. For the money, this lower kit will get the job done, especially if you're on a budget.
Everything needed
All the parts needed to build your lower are there. Still haven’t had the chance to assemble yet but everything looks pretty well made
Great price for everything you need
Very easy to put together, a little challenging putting the pistol grip. But no complaints. Everything you need for your AR for a great price
Looks good, not finished
Still making the purchase of all components, all lower build parts were included and in good order.
Great KIt!
Everything fit and works as expected, great kit for a great AR build. Would definitely use this kit again.
Very Discount
This was the second lower kit I purchased, very discount but gets the job done.
First build
First time assembling a striped lower and it was much easier than I expected.
Awesome kit @ a great price!
Top notch! Went together with no problems. Need a kit for a completed 80% lower I had.
Excellent lower parts kit!!
Everything went together perfectly, will definitely buy another kit for my next project.
Great kit for your first build!
I used this kit for my first ever AR build and it went perfectly. Would highly recommend this to anyone.
Discount mil-spec lower build kit i a nice set up for the money
Very satisfied with product and delivery.
Excellent for the budget build
Contained everything needed for a great budget build. Unless you are a serious competitor it makes no sense to spend hundreds to build out a utility AR. This kit gives you just what you need to do a great build. I normally switch out the buttstock collar tube lock for a sling attachment tube lock. Will purchase again.
Excellent lower kit.
Ordered kits to complete 2 Lowers, excellent quality vs. cost for reliable and affordable build.
Exactly as described
No complaints and quick shipping
Thank u
i have bought many kits from u-- great service and have good quality product--thank u
Great Kit for sure.
I will definitely buy again when im building my next AR. I end up using the lower parts kit on my build and kept the stock and grip as a spare.
Milspec lower build kit
Went together very well!
Discount Mil-Spec Lower Build Kit

Would Buy Over and Over Again

Exactly what I needed
AR15 Makes it easy for me to get what I need Everything fits great
Awesome experience
Great price and super fast shipping
Excellent Choice
Everything was absolutely perfect. Better than I even expected. Cant ask for a better lower set for the money.
Awesome kit
Kit was everything I needed to get another lower put together.
Great product
Assembly was flawless. Shipping was a little long but overall satisfied.
Always great parts
10/10 always great
Solid product for a fair price
This lower parts kit worked perfect in a 80 lower, no fitment issues at all.
Basic 6 position works as intended.
The mil spec lower build kit was installed on a purpose built 6.5 Grendel 18 inch bbl./ MLGS hunting rifle. The parts fit and functioned flawlessly even when rocking and rolling which the rifle will never be expected to do, but it's nice to know that there were no hiccups, even with a standard carbine buffer. It went bang every time I pulled the trigger and it had very little creep,… read more I didn't have a way to gauge the trigger pull except to compare it to the feel my colt A1 and it was really close. The stock has the normal slop attributed to a collapsible mil stock and I' m fine with that, especially for the price.
Great Inexpensive Low Parts Kit
My kit consisted of a Trinity Force Buffer Assembly, stock (it appears to be a Trinity Force L-E stock), A2 Grip, and a LPK with a polished trigger. Installed everything without a hitch on my lower receiver. Based on what I got, I'll be sure to buy this again.
Very happy
Looks great. Would definitely buy again
