Actual benefit of 11.5 over 10.5 and A5 buffer over carbine?
Background, I recently finished my 11.5 with A5 sbr and in happy with it. I followed the credible advice I found, and it seems agreed upon that these two elements are valuable
I recently was doing some department shooting and the conversation came up, once in tech talk and once with a buddy that has a DD 10.3.
When asked why this over the 10.3 , my answers were basically that there is a theoretical benefit.
With the 11.5 we've all seen the bcm explanation on dwell time, I estimate you get maybe 75-150 more velocity but the data claims are all over the place, but I don't know of any factual examples of reliability issues.
With the A5 it's easier when people recount it being smoother or not carrying multiple buffers anymore.
But when it comes to reliability, are there examples where either make the difference between a gun functioning or not, or is it all a theoretical improvement?
Again, I'm happy with the set up, just wondering if there is a more concise explanation vs some long winded discussion
