Airtech Studios TDC Advanced RHOP Arm - Tokyo Marui Style M4 Chamber

This R-HOP arm is designed to be a drop-in upgrade for a TDC (top-down-centre) evenly forced pressure set up.

Inspired by the self-leveling nub feature found on the Maxx brands for the Silverback SRS hop-up.

Features:

Perfect Self-Leveling TDC Top-down-centre force applied evenly on the R-Hop patch.

No need for modifying the stock arm and adding M-nub.

Easy drop-in with no modifications required.

M-nub provides an even distribution of force applied across the whole surface of the R-Hop patch.

For R-hop to function perfectly, the patch, arm, and barrel are only one part of accuracy, using high-quality ammo, a good compression system, Inner barrel stabilization, and keeping the barrel clean are also important parts of the total ultimate accuracy equation.
