Beretta A391 Gas Piston – 12ga – Shaft Style

This SRM Performance Products gas piston fits all models of the Beretta 391 shotgun which have a shaft style piston.

When used in combination with our gas seal bushing, your A300 Outlander shotgun will cycle more efficiently and cleaner.

It does not fit the A391 Xtrema models. The Xtrema models use the same gas piston as the A400 Xtreme models. It can be found at https://srmarms.com/product/beretta-a400-gas-piston-12ga-over-magazine-tube-style/
