Hello Everyone, Wish I had time to post more but unfortunately it's sporadic at best. I finally received the tax stamp for my Specwar 7.62 suppressor on August 8th. Yesterday was the first day I was able to hit the range with it. I noticed that when firing my M1A there seemed to be excessive backpressure coming out of the chamber when the can was on. I have an adjustable gas plug and was able to adjust it but I was wondering if anyone else running their M1A suppressed has run into this same issue? If so is there any excessive wear and tear caused by the use of a can? Any knowledge would be welcome.
