Continually had cycle issues with this gun since purchased. All different types of ammo, CCI, Remington, Winchester, Hornady, Cleaned, polished, adjusted the magazine guides etc., nothing made this thing run without short cycling. Finally after reading a bit I decided to try cutting down the recoil spring. (Worst case I buy a new one). I took three coils out of it and she is flawless now! Ran 40 rounds though it without any issue! I'm happy to have it working finally!
