Description

SilencerCo Piston .578x28 XL Features The SilencerCo Piston .578x28 XL is engineered to support tilting-barrel pistols by allowing the suppressor to move independently of the barrel during firing. The XL length offers additional thread engagement making it especially useful for hosts with extended barrels or recessed thread shoulders where standard pistons may not seat correctly. This design helps maintain proper alignment and consistent cycling. Constructed from heat treated 17-4 stainless steel the piston delivers excellent wear resistance and long service life under repeated use. The black finish provides corrosion resistance while maintaining a clean professional appearance. Compatible across multiple SilencerCo suppressor families this extended .578x28 piston expands host flexibility for multi-platform suppressor setups.
