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.

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.

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
