Strike Industries Modular Stock Alpha MKII Chassis for Sig P320, Black Aluminum, Ambidextrous

The Strike Industries Modular Stock Alpha MKII (Strike Industries part no. SMCAP320SV2BLK) is a black aluminum chassis built to turn a Sig Sauer P320 into an ambidextrous, stock-equipped platform. Strike Industries machines the chassis from full aluminum and includes both a Picatinny rail backstrap and a lighter, low-profile backstrap so shooters can choose the configuration that fits their build. The chassis ships with a spare magazine holder, a multi-pattern optic mount with mounting hardware included, and an extended ambidextrous charging handle, along with a modular extended magazine release on both the frame and the mag holder. Because it is a full modular system, it stays compatible with additional Strike Industries SMC accessories as a shooter’s setup grows.
