This valve not only repaired my non-functional C02 WE Hi-Capa magazine but it majorly upgraded it. You can't see it in the picture but once you see it. The out put valve has 3 holes. It's almost pure airflow. Stock Valve's are 1 hole. Common customized valves are 2 hole. This one has THREE holes!
I was all giddy about getting this valve into my magazine. Once i loaded it up. Oh man.....the sound...the power! It increased FPS by 50 and the blow back feels amazing. I have a upgraded 150% spring for my blow back mixed with this valve. My pistol's ROF is as fast as i pull the trigger and can hang on! The recoil makes it feel like a magnum now!
I'd recommend a blow back upgrade if you plan on installing a high output valve! You'll love it.
Increases FPS over a stock valve by 50FPS
Blow back feels amazing....Words can't describe it
Simple to install if you do not have the proper valve tool as it has a entire flat head top to it. Simple as a perfect sized flat head will do the job. Make sure it's SNUG! Clean your threads before installing too!
The price seems like the only con but if you willing to spend $18 on it then you will be getting quality i can guarantee that much. I don't regret buying it even though my pistol is barely used.
