Best LPK
Best lower kit build for the price. Quality and never a problem with anything fitting.
-
Great value.
This LPK is as good as many more expensive ones and better than any I've found in the price range. MCS is my new favorite place to go broke. ?

Excellent LPK for the money

Good Deal
Everything seems decent quality when arrived. I have no installed yet into my lower. Let it be known I ordered 3 kits and none of them had the dual selector only the single. Giving this a 5 star thanks to Joel. He took care of me asap sending me 3 duel safety selectors within a minute. Thanks again Joel, I hope you see this.
