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.)

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.

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.

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.

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.

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!

Matthew G.

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.

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.

Best kit I’ve used

Allen B.

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.

Discount is the key word

Sean P.
3 years ago

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.

Robert C.

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.

Clifford S.

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

Brian B.

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
