What buffer are you running in your middie?

[WaldoOneFive]

I've got an H buffer in my BCM midlength and it runs well so far. I'm using only NATO-pressure 5.56 loads (M855) and am thinking of bumping up to an H2.

You state in your post that you have an "H" buffer in there now and it runs well... So why do you want to change it? You know: "If it ain't broke.. don't fix it?"

Where is your brass landing currently?

I have two 14.5 BCM Middy's (one Govt, one LW) and both run BCM BCG's with H buffers and run flawlessly.

Have a 16inch BFH middy and have been running an H buffer since day one. With brass cased .223, 5.56, and Hornady steel match I have never had an issue, even when dirty. Now Tula and Wolf... well it will generally fire and cycle fine but I get failures to lock back and the occasional instance where it won't pick up the next round from the mag of those two ammo often enough that I would consider dropping to a CAR buffer if I ran them for any length or exclusively. However, since I am down to under 500 rounds of those two I just use to for failure drills when at the range and when I feel too lazy to pick up brass.

car buffer... guess i just dont know better.

H2 and white springco. 16 middy
A5-3 in another.

They both run with whatever I put in them.

Same set up with blue springco and very similar experiences here. I have experienced failure to lock back with only Tula which is known to have pressure issues. I can't fault any rifle that stumbles firing that junk. But even Tula has never failed to feed for me. All other factory brass & steel cased ammo has cycled flawlessly. I have had no reason to change to anything other than the H buffer.

Indeed. And I should state that it is not always that it will cause issues running the Tula or Wolf. Have taken them to the range and run 100 rounds without issue. Then at times have a couple boxes and every five rounds I am clear malfs. But with NATO pressure 5.56 and .223 brass cased ammo such as PMC Bronze I have never had an issue so I am not, and can not in good conscience say it is the rifle's fault with that ammo. What should also be noted is that an old Bushmaster Patrolman that I own has also had issue with failures to lock back with a lot of tula I ran that the BCM failed damn near every time to lock back on. So if an over gassed Bushmaster with a CAR buffer and an old spring won't lock back on that shit......

A5 H4 with Sprinco Green spring. Works on both DD and BCM 16" midlengths.

I'm running a standard carbine buffer in my BCM 14.5" middy and it runs perfectly. With factory 5.56 and my reloads. It's been perfectly reliable for over 1K rounds.

ST-T2 (4.1oz.) with a blue Sprinco spring.

I know the buffer is considered another snake oil item by some, but I've had no issues with it.

I don't shoot Tula or Wolf though.

16" mid with .078" gas port, A5H3, Sprinco green, LMT Enhanced carrier. Flawless with 5.56 and all the .223 I've tried.
