I am planing to buy an S&J custom Titan compensator Recoil Brake for my GP75. The Compensator demensions according to the vendor for the 7.62 are industry standards 14 mm X 1 L Threads. Now my question to everyone is, will that fit my GP75 barrel without any problems, or will I have to make adjustments? Thank you all for any help you may provide! I am new to this and learning as I go. Rom.
