PPS Aluminum Hopup Arm for Type96, SD96, APS2. High performance upgrade arm for high power sniper rifles. This is a CNC'd aluminum replacement for the brittle, plastic stock part on most Type96 rifles. Until now, you had to spend all your cash on a complete hopup replacement to get the accuracy needed to consistently tag opponents at 100+ yards, but no longer. The bar-bell shaped nub will cradle the BB to center it in the barrel for consistent hop and accuracy.
