    Which would you prefer?

    So having built roughly 4 ARS already (with 2 more on hold) I started to think about something. Something more in line of extreme abuse type rifle, one that I would have no problem taking it everywhere, a do it all type weapon and also the one that's not in my inventory.

    So far all my ARS are 16+ inches middys in barrel length with one being a 10.5 carbine, I was missing the medium length, the 14.7. Having to stay within legal length a pinned 14.7.

    Personally I think the 14.7 is the perfect compromise between a 16 and 10 in terms of a do-it-all type scenario. However there's a problem, The gas system option of carbine or midlength.

    Can any of you chime in with anything to contribute on either gas system for a 14.7?

    Ultimately, I want it to be reliable and never fail in the firing system. I can't decide which route to go.

    Mid length, no questions. I've never ever had reliability issues in either of the 14.5" I've had, and less felt recoil is a plus.

    My 14.5" is a BCM BFH middy, I'm also using a H buffer. With ammo like Tula it sometimes will not lock the bolt back. It may do it with a carbine buffer but I haven't tried.

    Never run a H in mine, just carbine and a spikes t2 once. No problems with the t2. Shooting mostly .223 plinking reloads and m193. I've never run steel cased ammo, so ymmv.

    So the consensus is mostly for midlength. I heard and read most people who do 14.7 run on a middy gas system.

    I honestly never felt a big difference between mid and carbine systems in a 14.5" barrel, but that's just me.

    If your talking about building the most general purpose AR you possibly can, a carbine length gas system will cycle/ and or lock back with a wider range of ammunition more reliably... But at that point you are talking about cycling 98% of ammunition versus 96%

    why are you looking at 14.7" and not 14.5"?

    No real reason, plus I figures that . 2 inches won't make that much of a difference, but correct me if I'm wrong.

    It's also dependent on what the retailer is offering :p

    I 'm not looking at a velocity chart right now but your probably talking about a negligible difference in velocity between the two barrels. You woldn't feel a difference in weight or point-ability unless the 14.5" and 14.7" were side by side.

    I have to agree with Schambers here. The mid-length may shooter a little softer but not much. I'm not downing a 14.5" middy, as it's the setup I've been playing with most lately. I really like my middy, but in a 14.5" the difference is marginal over a carbine. Now in a 16" there is a lot bigger difference since a 16" carbine is way over gased.

    Soisauss if the barrel your looking at is a Centurion Arms 14.7" carbine length, I used to have one and it was a great barrel.
