The mag catch sits more flush in every position

where as when the stem is longer the mag catch can only be threaded in so much

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.
