Guiltine’s Executioner Bucking for M249 V2 vipertech The mag catch sits moreImprove your accuracy!! Before buying a bucking, make sure that a dirty barrel or inconsistent power output isnt 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.
