EMG Atlas Flat Hop-Up Bucking


A flat hopped bucking reminiscent of the popular Madbull Blue bucking. This saves you time from having to shave down the mound and locking ridge for flat hops and R-hops. This bucking has been our go to for our R-Hop kits because of its great seal and durability.

  • Smooth-bore design removes the need for potentially damaging modifications to install
