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.
