[QUOTE="ARlife4me, post: 2978242, member: 105694"] On non-adjustable gas, then yes. Buffer weight doesn't change for gas nor add to the weight of the cycling. This isn't hypothetical, it's factual on following statement(s). With an agb where it's tuned to the correct ejection pattern with a lighter bcg (spring and buffer are not important at this time although required) will need less gas. Now snap in a heavier bcg and it will short stroke. If something is "crashing" into the buffer it has to much gas. If you use a non-agb (gas port being at optimal size) using a lighter bcg, the use of a heavier buffer is needed (not necessarily a stronger spring). What you have found in your test seems to be different than what I've tested. Test done with pmc m855 and m193 in 5.56 and wylde chambers. Test done in 6.5creed AR10's used Hornady match 120a-max. Test in 308win AR10's used pmc bronze 147gr (m80) 7.62x51. I haven't done any in 6.5gren, 300bo or 6.8spc2 yet. Test is uncomplete on 260rem AR10's and 7-08rem. [/QUOTE]
