KNS Precision Smith & Wesson M&P Build-A-Kit Gen 2 Mod 2 side plate NRTHP BK2DE2OD2. These pins are TOO LONG for regular forged aluminum AR-15 lower receivers and will stick out the sides quite a bit. THE TORQUE SPEC ON THE SCREW IS 11 inch/lbs. MAXIMUM. We recommend 8INCH/LBS of torque. THIS IS FOR THE POLYMER .22LR S&W M&P15-22 ONLY. FOR ALUMINUM M&P-15 LOWERS PLEASE USE OUR STANDARD NON-ROTATE PIN SETS. These are the STRONGEST pins that can be produced and were designed to withstand the high impact of full and semi-auto 9mm .223 and 7.62mm suppressed weapons. The pins are stainless steel. Black sideplates are black nitride treated all other color options are DuraCoated.
