Like many other builders, I've been using CMMG's Builders LPKs for several years. A few weeks back I stumbled across these on sale for about 30% less than I was paying for he CMMG LPKs, so I ordered four of them. When they arrived I was impressed, so I used them on two premium lower builds on Mega Arms receivers. Every part fit perfectly, and the finish is excellent+. I'm very pleased with the result.

I used this kit on an Aero Precision pistol build because the Aero LPKs were hard to find. I expected decent quality and that’s what this M&P kit delivers. The bolt catch is distinctively S&W, which is fine. Great parts at a great price.

Safety selector was grainy and the safety selector detent was corroded. Once assembled, the selector sticks and won't turn over. I trimmed the selector spring a little to try and get the selector to turn over but it's still very grainy. I won't rely on something this sketchy in my LPK and now I'm stuck buying another kit from another company. I bought this kit thinking S&W had a good reputation, wth.

Bolt catch broke off after 200rds. Would not depend on this kit in any capacity. Spend a bit more to get something reliable, because now Im stuck buying another bolt catch. It doesn't appear to be defective either, it just straight up is built with weak steel.
