For: Echo 1 M14 Hop Up Chamber
This is a good replacement hop up, but I wouldn't suggest it as an upgrade. I just got this for my Kart M14 MCR that came with a broken hop up. This dramatically improved the accuracy, range, and overall performance (obviously, the old hop up was broken).
Comes with everything needed for a hop up except for a bucking and barrel
The threading on the adjustment screw didn't work on my Kart M14 MCR. Maybe it's just mine?
