RRA LPK REALLY IMPRESSED
Works and function's well. Much better Trigger & Hammer, and crisp- no creep than Anderson or AR Stoner LPK'sDefinitely recommend for quality and at this price you won't go wrong.

Won't buy again
Will not buy from Rock River again. The magazine release was .0002 over the edge of the well. Had to file the back to get it to seat properly and it left a rub mark on the edge of the well. The selector switch sits loose on the detent pin because of the grind. Poor finish on the parts. Just poor quality control. Really disappointed with this kit.
