Achieves a stronger hop than the stock hop up. Caution is required with use, if you apply too much hop it may cause your rifle to jam. Red in colour. Compatible with standard hop tensioners. The front and rear positions of the hop tensioner and the angle of the arm at the start of hop application have also been optimized, allowing the hop packing to be pushed out efficiently and reliably.
