    What not put the originals back or downgrade rather than stay with something that isn't working as well as you hoped it would?

    My question is whether 14.5 inch mid length ARs are ammo sensitive. That is, would I be able to run full 5.56 NATO ammo as well as quality .223 ammo (PMC and Federal)?

    Thank you.
    Why not go with a 14.5 carbine instead. The 14.5 carbine gas with the standard H buffer is very ammo tolerant and will fire everything from full power 5.56 NATO down to the weakest reloads. Plus you don't have to buy a buffer collection to support your carbine.

    I've owned four. One CMMG. Two Sabre Defence. One BCM. None have been ammo sensitive. All have had H buffers.

    To give a couple more examples and echo what has already been stated:

    - CMMG (likely overgassed) ran everything fine with a ST-T2 buffer
    - BCM ran everything fine with an H buffer

    (Both with BCM auto carriers and standard carbine action springs)

    They didn't have any 14" versions at the dealer up here so I had a choice between the 10.3 or a 16". So I ordered a Daniel Defence in a 10.3. It is the mk18. So I hope I won't have any problems with ammo.

    Ha! It is your fault Buford!! It's cool though, and I will eventually default it back to its working state I just keep it to tweak. I mostly shoot my 6720 which cycles everything under the sun.

    I have 2 bcm lw mid with 14.5 barrels.
    Both have standard carbine springs and H buffers
    I shoot mainly 223 tula. I had 1 fte with tula recently. Most likely needed lube.

    Have shot a bit of 5.56 in it too.

    I really can't complain. I'm quite happy with my setups

    I have a Bravo Company Manufacturing 14.5" barrel with mid-length gas system and it has run perfectly on both 5.56 NATO and .223 Remington, with standard carbine recoil springs and buffers from carbine to H3.

    Cameron, with that gorilla upper half you have, that rifle's just scared to not cycle whatever you feed it....

    My BCM 14.5" runs strong, but choked a few times on Tula when I was out with Munch520. It could have been the mags or the mix of brass and steel though, I can't say for sure and wasn't too concerned about it. Other than those few rounds, the other six or seven thousand have been good.

    Proven combat techniques may not be flashy and may require a bit more physical effort on the part of the shooter. Further, they may not win competition matches, but they will help ensure your survival in a shooting or gunfight on the street. ~ Paul Howe
