DPM Recoil Springs for Bul Armory BUL SAS II SL, SL AIR & SAW 5" BULL BARREL (9mm, .40S&W)

The DPM Mechanical Recoil Reduction System for Bul Armory SAS II SL, SL AIR & SAW 5" Bull Barrel is a direct replacement for the stock recoil rod, offering enhanced recoil management without altering the pistol’s configuration.

This system operates using a multi-spring intricate rod (3 springs), with an internal third spring that prevents the slide from ramming into the frame. It includes three different-length spacers and three external springs, allowing for 9 adjustable user settings to fine-tune recoil performance.

The spacers adjust the buffer force (slide full open position), while the external springs adjust the slide’s closed position (slide on the battery), providing a customized shooting experience.
