@98Z5V I know the benefits of heavier buffers, and prefer them myself. Helps reduce felt recoil, makes the gun run more smoothly, more reliability with hot loads or suppressed, minimize wear and tear, and better for more powerful calibers than the basic buffer system was originally designed for.
But with all the threads out there on this subject, we don’t highlight the why we suggest going with a 5.4 oz buffer as much. I know you get tired of the same topic over and over, but it isn’t as black and white as you make it out to be.
SHOULD a 308ar have a a heavier buffer than the “standard” 3.8oz 2.5 in buffer?... HELL YES.
CAN some 308ar function with a 3.8oz buffer? Depending on the parts (maybe it is because they are made cheaply), YES some can.
Never once did I tell cwouscg his buffer was good to go. In fact I told him if he can return it, than to go with the armalite receiver extension kit or buffers and spring from heavybuffers.com. And I told him problems could come from his choice in buffer.
Tom I have a lot of respect for you and i rarely question your knowledge, not a time even comes to mind. But, if someone already has the parts and can’t get their money back, it isn’t going to hurt to try them out. If they need to change parts than they can, or upgrade later on their own time and budget if it works. $75 can be a lot of money for some people, I know my wife would throw a fit if I spent that without talking to her first since we live on a single income.
