I personally have uppers in 10.3, 11.5, and 12.5 waiting patiently for the day my BCM lower is no longer a paperweight. If I could only have one ...the 12.5 noveske chf & Nsr combo would be hard to deny

This is why I said what I did about trying to figure out which length is "better." It's like asking which is better: a SUV or a pickup? They both can do similar things, but one might be better suited to your actual needs. In the case of barrels, it's more about how it's made than the length. Gas port and profile are the two main ones, IMO.
Gas port because it can affect how it will run with specific ammo, and whether it's suppressed or not. I'm not a huge fan of having to play with gas blocks. For me personally, I'd rather just start with a port that's built to spec. Then again, I don't shoot Tula, so I'm generally not worried about underpowered ammo.
Barrel profile can have just as much to do with balance as length. I have a 10.3, a 11.5, and a 12.5. With the 10.3 (M4 profile) and a can, it's very nice to hold and only slightly nose heavy. The 11.5" would be the best all around balance with and without a can, but I have a "standard" profile BCM barrel on it, which heads weight, along with a piston system that's on there, which makes it more of a pig. Add a can, and it's very nose heavy. My 12.5" is an absolute dream to shoot unsuppressed. Super light, well balanced with the rail and profile, and super reliable. Add a can, and it gets a bit nose heavy.
Out of all of those, there's no "wrong" choice. They're all accurate, have no trouble hitting Minute of Steel at 200m and beyond, and run great with spec ammo. But they each have they're peculiarities because of their other traits beyond barrel length.

I plan to this weekend....if life does not throw any crazy stuff at me from now until then. I finished a build and am itching to try it out.

On an off topic, but still related to SBRs, would an A5 type buffer system be advisable with a 12.5 middy barrel like this? Or for that matter a 14.5 middy?
I have a BCM A5 kit, but since I have never used a system like that i'm sketched to use it for the 14.5" middy noveske build it was planned for

I've seen nothing but positive reports of the A5 with bcm 14.5 middys. It does depend on which buffer you use, but the A5 is far more forgiving. It took me a long time, but I finally switched over all my carbine lowers since they are much more flexible when going from suppressed to unsuppressed, and I don't use adjustable gas blocks.

I plan to test it with several buffer weights and an A5 buffer.

Anyone have any rounds down range yet?
Anyone suppressing theirs?
Anyone that hasn't built theirs up able to measure the gas port size?WWW.TACTICALYELLOWVISOR.NET

I haven't shot mine yet, the main reason is I don't have it set up. Right now it's matted with a KX5 and a MML handguard, and I'd rather run it with a correct length handguard without a KX5 and with a can. We're slowly packing for a move, and I've been swamped with other things, so it's probably going to be awhile until I get some lead down range with mine. Hopefully Doc will get his up and running before I do.

Mine is built, I have 3 different buffers and an A5 buffer to try it. I have two different cans I will use also. I just need to get some range time with it.

Rainier Arms UltraMatch .223 Wylde Mid Barrel - 12.5"
I had planned to run the bcm A5 Kit and then play around with different combos until hopefully it ran well with either a 16 or 14.5 middy upper. But now I'm not so sure..
Would I be better served tearing down my factory bcm lower in favor of the A5? It's on a form 1 and will see lots of flavors of uppersLast edited by DutyUse; 5 June 2015 at 06:18.
