Great Parts Kit

I have built several lowers using this parts kit and it always exceeds my expectations. I have only used this kit for the last couple of years after trying some competitors and finding a little rust here, a missing part there. If you are needing a LPK, this will not disappoint.

Rise LPK

I have purchased and used many of these and they are the best hands down. I have seen missing parts, rusted parts and damaged parts, just never in a Rise Armament package. If you ever do have a problem, well you purchased it from Brownells right? Guaranteed for Life...

Always good to keep spares around

Needed a few pieces for a new build so I ordered a couple of these. Never hurts to have spare small parts around. Same quality as other Rise parts I have, good stuff.

100% satisfied

I have used several of these lpks and have never had the slightest issue with any of them. They are great quality, well laid out, and made to spec. A+

Precisely what's needed

These are the critical little parts that are needed when replacing/working on any AR. These are the little ones that break, bend, or simply run and hide during dis-or-re-assembly, and are the essentials for the completion of stripped lowers during modifications/rebuilds. Priced right, and the correct assortment needed without some of the more major parts, that are specialty purchases. Always keep a couple on hand - saves time.

Quality Kit

I purchased these to have on hand for replacement parts in the lower receiver assembly. The parts appear to be of excellent quality, and were a definite value when compared to buying individual parts a piece at a time.

Oops plus

I bought this as a glorified oops kit. Needed takedown/pivot pins, and all the springs and detents. Takedown/pivot pins are gritty. Everything else works well though. Cost about the same as an oops kit so I didn't expect much.

Good!

I have used this parts kit several times. It has everything I'm looking for. My only gripe would be the finish on a few parts is a little rough, and its been that way everytime. Great kit none the less
