I am curently saving up for a Bravo lower. It comes with a staked standard carbine receiver extension. I am debating about switching to an A5 tube after reading good things about it on here. If I read correctly, the A5 is a good option due to its flexibility over different gas sytems and barrel lengths. Irrelevant in my case as my upper has a DD 16" middy barrel and I won't be doing upper swaps.
However, I read that the A5 would be smoother(due to the rifle spring) but is there a difference in terms of it being softer on standard wear and tear of parts vs the carbine tube? Newb question I know but I would appreciate it if someone could could answer this for me.
