AUSA 19 – B&T Universal Service Weapon for P320

In the comments in the article about the P320 lower for the B&T APC-9, there was some confusion over the USW and APC-9.

This is a drop in lower receiver for the SIG P320 Fire Control Unit and Slide rather than a full firearm. Like the original USW, it also incorporates a right-side, fixed-length, side-folding stock.

It also requires a P320 magazine release. Additionally, a red dot optic can be mounted, but it has to be on the P320 slide you’ve provided.

    Still a fan of the FLUX MP-17, would have been interesting if it was out during the weapons trials for the Aircrew Self Defense Weapon (ASDW)

    It’s about time for this and the similar products that have recently come out. The modular nature of the P320/M17 platform has been begging for good buttstock/”pistol brace” conversions since its inception.

      Everyone is to busy making Glock slides and barrels. Because the industry needs more of that.
