Most Helpful Positive Review Excellent LPK
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 A...

Most Helpful Negative Review What decade were these packaged?
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 st...

Pretty terrible Quality

by Joe, Verified Owner from CA, United States Written on March 7, 2021
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.
Pros:
  • None
Cons:
  • Breaks easy
Best Used for:
  • failure
Would recommend: No

solid parts kit

by freedombirdies, Verified Owner from IA, United States Written on October 31, 2020
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.

S&W Lower Parts Kit

by Tactical Reviews, Verified Owner from FL, United States Written on August 5, 2020
One of the best deals going for your lower receiver build, comes with everything you need minus the trigger assembly. Everything in this kit is made of high quality and durable materials. Pick one up while you can for this price always a good time to keep a spare parts kit around or in your range bag.
Pros:
  • Well organized L.P.K., quality materials
Cons:
  • No cons other than the safety is not ambidextrous.
Best Used for:
  • Your lower receiver build/ spare parts kit
Would recommend: Yes

Seems just as good as spikes and bcm

by Heed, from VT, United States Written on February 23, 2020
Even though s&w doesn't use these in their rifles this seems like a high quality kit with machined parts. The key to a good lower parts kit is machined not mim parts. It would've been nice to see that they used Schmid selectors and safeties, but they don't. For the price it's worth it.

complete kit

by Vinniy, Verified Owner from CO, United States Written on May 24, 2018
Good and complete basic kit for AR lowers. everything is separated by a blister pack. if you get other parts that are considered "upgraded" you end up with extras that you can count on. It would be nice if Smith and Wesson offered an Ambi kit similar to the M&P 10 set up. I am sure that would require an Ambi lower though.
Best Used for:
  • Lower build

Awesome simple parts kit.

by Yack, from CO, United States Written on May 15, 2018
Great, simple parts kit for the price. Don't always need ambi controls, or extended take downs and can drive the price of a parts kit up. This kit is simple and works for a great price. And if you're buying a trigger separate this kit is perfect.

Lower parts kit

by ClemsonWill, Verified Owner from SC, United States Written on March 26, 2018
This Smith and Wesson parts kit worked perfect. I honestly like it much better than some of the more expensive lower parts kits I have used. I love how everything was laid out in the plastic so that it was easy to see and pick the part you wanted. I didn't have any quality issues. Everything fit perfect on my PSA lower.
