Airtech Studios ARH Advance RHOP Arm Krytac M4 & Kriss Vector Hop-Up Rotary Chamber

Thinking of installing an R-hop set-up to your Krytac build? Instead of modifying your stock ARM by cutting /sanding which may run the risk of an unbalanced force pressing on the R-hop patch - our R-HOP arm is designed to be a drop-in upgrade to mitigate the risk to give a perfect, even forced pressure.

 

Features

 

Save cost on expensive aftermarket hop-up chambers for R-hop usage

No need for modifying the stock arm and adding M-nub (our arm provides both)

Easy drop-in with no modifications required.

Made from tough fiber polymer injected plastic
