Guiltine’s Executioner Bucking for M249 V2

Improve your accuracy!!

Before buying a bucking, make sure that a dirty barrel or inconsistent power output isn’t the cause of your inaccuracy issues!

Improved O ring cutout for openbolt/M249 users!

-Guillotine custom contact patch design.

-Cutout for tension O rings specifically for open bolt guns such as the VFC M249.

-VFC M249 option comes with 2 o rings for proper tension.

I highly recommend 70° for most applications. Professional installation required.
