B&T Compatible Accessories

B&T's lineup spans several distinct receiver interfaces — APC, GHM, SPC9, TP9, and USW — and fitment precision matters more here than on almost any other platform. A3 catalogs every B&T-compatible product against the specific model family, with explicit interface notes on each PDP.

Swiss-made hosts deserve hardware that matches: the A3 and HDA3 products listed here are machined and fit-checked to the same standard, with the firearm-adapter variant locking your exact B&T model at checkout.
