Smooth recoil impulse - Radian Weapons Compressor Quick Tune Guide Rod

Smoother recoil impulse. Slightly less felt recoil but very noticeable. Overall the gun is more enjoyable to shoot and follow-up shots are easier because of the more manageable recoil impulse. Spring is very stiff when new but breaks in quickly. For me it only took 200 rounds to notice the break-in because it gets a little smoother.
