B&T Alpha Piston Features The B&T Alpha Piston is machined from heat-treated 17-4 stainless steel for the strength and corrosion resistance required for sustained pistol suppressor use across a wide range of environmental conditions and round counts. The 1/2x28 thread pattern provides direct compatibility with the most common pistol threaded barrel standard making the Alpha Piston a straightforward upgrade or replacement for shooters running B&T suppressors and most other major suppressor brands. Consistent alignment through the piston s tight secure fit ensures reliable suppressor performance and minimizes the risk of misalignment-related issues during operation. The heat-treated construction holds up through frequent caliber changes and repeated suppressor attachment cycles without degrading dimensional precision or fit over time. Compatible with Glock SIG and other threaded-barrel handguns the Alpha Piston provides broad platform coverage in a single precision-machined component. B&T engineers the Alpha Piston to the same precision standards applied across their suppressor and accessory lineup for long-term reliability shooters can count on.
