Aero just ran their deal where it’s 25% off a barrel and you get a free VG6. I just ordered an 11" barrel and Gamma brake for $108. The 8" would have been less. Set it up in an EPC upper and you won’t be dissatisfied. They work well on the PSA 9mm lowers, as well.
I keep reading about how difficult AR-style PCCs are to set up, but I don’t get it. I feel bad for anyone that has ANY issues with their stuff, but I must be really lucky? Over and over again?
