Factory replacement screw-in rear velocity adjuster for the Spyder .50 caliber Advancer. It replaces the rear end cap and includes the integrated spring guide to help prevent spring kinking, which can cause velocity problems.
The flush design requires a small Allen wrench to adjust the velocity. This unit is field and tournament legal, eliminates the need to cut your main spring or disassemble your gun, and adjusts from 180 fps - 300 fps.
A handy drop-in accessory made from black anodized aluminum. For more Spyder parts, see Spyder .50Cal Advancer Replacement Upper Body Red or browse Accessories > Bags & Backpacks.
