The Hinderer Modular Backspacer System was developed out of a need to be able to quickly customize your knife, while increasing the functionality of your knife.
This contoured backspacer is just one of the many options available for the H.M.B.S. system.
This backspacer is anodized blue and will include one (1) matching forward stand off. It also includes one (1) 0.050″ HEX screw preinstalled.
*Please note- you will need the H.M.B.S. base hardware kit installed on your 3.5″ XM-18 for this to fit.
