Factory replacement screw-in rear velocity adjuster for .50 caliber Advancer. May fit other 50 caliber Paintball markers but NO guarantees. Replaces the rear end cap and includes the integrated spring guide which prevents spring kinking (which can cause velocity problems). Flush design requires a small Allen wrench to adjust the velocity. This makes this unit field and tournament legal! Eliminates the need to cut your main spring or disassemble your gun. Adjustable from 180 fps - 300 fps. A very handy drop in accessory! All black anodized aluminum.
