Buffer for 14.5"

[Game Time]

Does a 14.5" upper require a heavy buffer or will a standard buffer work?

[Linus]

I'm guessing its a 14.5" upper with a carbine length gas system, which in this case a heavy buffer can improve cycling by slowing it down a bit. Do you have a Semi or Full auto (heavier) BCG? If you have a FA BCG that might be all you need.

Yeah, it will be a carbine length gas system. I'm ordering a BCM 14.5" carbine with the full auto BCG. I'm just wondering since I'm placing the order, if I should get a heavier buffer. Maybe the Spike's ST-T2 if it's necessary.

I have an auto BCG and an H2 buffer in my BCM and it works great. I think an H3 buffer will even work.

I have a standard buffer on my carbine length 14.5 with a semi BCG and not a single problem!

I run a heavy buffer with my carbine length 14.5"

[damndave]

I ran a standard buffer and no problems at all

Same here...2 uppers I have are built the same (14.5 carbine, with standard buffer) No issues

I have a BCM 16" middy with an auto BCG and H buffer, it runs great. So I guess what Im trying to say, is.. an H buffer for your 14.5" wouldnt hurt..

[Linus]

An H buffer + a semi auto BCG will not hurt but increasing the weight of wither the buffer or BCG improves operation by slowing it down. Doesn't mean you need a heavy buffer or FA BCG to run reliably, its only required when short stroking is present.

I run a H2 on my BCM carbine. Use to run a H, but the H2 is smoother and less muzzle rise. I put the H in my BCM middy.Check this article. The person who wrote it, is a REAL TEIR 1 Operator, not some wanna-be.. http://www.defensereview.com/the-big...m4-unreliable/

i'm using the standard buffer with my 14.5 upper and haven't had any issues.

necropost but maybe you guys can help me

Just came back from zeroing my new BCM 14.5 mid-length with perm FCS556 comp.

I had a ton of FTFs, like every magazine had 1 or 2. I'm running a standard buffer with a semi auto carrier. I'm going to buy a H2 and see if this fixes the problem.

Besides that problem, gun's pretty amazing and light!

Edit: Ammo was Wolf FMJ 62 Gr

I also had my BCM 20" rifle upper (full auto BCG) on an A2 lower. That worked 100% flawlessly with the same mags I used in the middy.

Might wanna try some different mags. How many different mags did you try? Most FTF issues that I have seen are from bad mags. Mostly 10/30 and 10/20 mags. My 2 cents: Get a 10/10 mag, use a H or H2 buffer , get a Quality F/A BCG(preferably BCM), and use some quality ammo(not that a BCM cant handle Wolf ammo)..

Buying a H2 buffer is like putting a bandaid on a bleeding laceration.

Get different magazines.

Switch upper and lowers and try to isolate the problem.

Check your FCG and make sure everything is installed properly.

Inspect your BCG and bolt (and everything inside).

Use different ammo (although Wolf is generally underpowered and has deep seated primers, it usually has no issues. I personally have fired 5-6k of wolf with no issues.).
