Buffer weight for 5.7 ar pistol running a frt?
Hello everyone, so I'm going to be building a AR pistol in 5.7x28 with a cmmg 8-in barrel with there their bcg and a atrius forced reset selector and was wondering what buffer weight i would need to use for it to run smoothly and not have to much bolt bounce?
