[QUOTE="ARlife4me, post: 2861155, member: 105694"] If it's taking the actual rearward movement of an automatic then something is wrong. On those doesn't use a buffer tube I have no idea? As an AR platform goes it shouldn't be an issue with a heavy optic or any other added weight. I've had 3.5# AR's to 15.5# 1's also. As long as the gas system is tuned to the bolt, buffer and recoil spring all is good. Don't choke the gas in this case if you feel the port is sized well enough, just add weight to the buffer as a heavier spring doesn't really help dwell time only rebound. This is what I've found and other might have found a different method? I've changed carrier weight, buffer weight and recoil spring tension for various cartridges with different powers. Another thought is the B5 system..........might not make sense here, but give it a go. I would go with an h3/h4 buffer (5.3-6.5oz) with the rifle length spring. I can still send you the real heavy buffer I have for you to try (9.3oz), if you're interested? I ask for nothing in return as only too help you in your quest! [/QUOTE]
