Just got back from the range. Super super soft shooting. I wish I had another 9mm pcc to compare with. I'll have the opportunity to run it against an mpx hopefully soon. I noticed that it requires a break-in period because the arms also engage with the buffer tube opening. After it cut a channel into it and the rollers were the only part making contact, it became easier to charge. One strange thing is that the buffer spring wasn't strong enough to put the bolt into battery. I'm wondering if Corey had a chance to test a flat wire spring with the system.
I'll be throwing a brake on the gun. My 2 taps were inches apart. Even though it shot soft, my dot didn't return to where it was unlike the taccom magnetic system. But it's probably because I'm not used to it yet.
