I've been using a friend's long mag running on HPA with a palmers 0-200psi regulator. Without any upgrades to the magazine or striker spring, I'm getting FPS fluctuation of about 4 FPS, although I do occasionally get an outlier about 10 FPS off.reezo said:I am considering getting one, as well. I've read mixed reports of their gas consistency etc.. if you can please let us know your experience with it! It would be golden!
Enjoy the new magazine
