This CNC'd aluminum hop-up adjustment arm is designed for Tokyo Marui VSR-10 and JG Bar-10 style spring-powered, bolt-action rifles. The high angle of engagement provided by the arm allows for a wider range of hop-up adjustability and precision machining gives an improved fit for the part, which reduces inconsistencies when shooting. The sturdier, more adjustable arm allows for easier use with heavier BBs, such as .40 gram sniper rounds, removing unwanted flexing or warping from the unit's usual plastic parts.
There are two types of DangerWerx HE Levers for the VSR-10. The Type A is for use with standard or stock hop-up buckings and nubs. It has a notch for the stock nub on the arm. The Type B is for users with upgraded hop-up components, such as H-nubs, W-nubs, and flat nubs. To be sure you're purchasing the right HE Lever for you, you can consult this guide.
DangerWerx designs and produces aftermarket parts for a number of airsoft replicas, including thread adapters for barrels and CQB-velocity valve parts for popular gas blowback guns.
