MIL Spec buffer or the larger buffer?
I see some of the more expensive guns have a mil spec buffer. The other less expensive rifles have a larger commercial buffer. Whats better and why? Thanks.
I don't believe there is any PRACTICAL difference.............
Most of the commercial tubes are made from 6061 T6 Aluminum.
The Mil-Spec tubes are made with 7075 T6 Aluminum, which is twice as strong as 6061.
Plus the Mil-Spec has full depth threads.
Mil-spec, if for no better reason than you can guarantee any stock made will be offered Mil-spec first.
A truly MIL-SPEC receiver extension tube will be sturdier and thus last longer in more rugged conditions. You may not need this level of robustness, but it can't hurt. There are now a number of MIL-SPEC-like tubes on the market. They are the same outside diameter as the GI parts, but offer things like more position stop holes, differing types of adjustment mechanisms, etc. I am not sure if any of these is made to MIL-SPEC production standards, so I can't say that they will be as rugged as the GI parts. If they come from a reputable source, they should be at least very close to the sturdiness of MIL-SPEC tubes.
I'm sticking with the real deal because I've never seen a need to go for the extra features.
