It all depends on the manufacturer as some are more gassed than others, but there is plenty of data out there now for most flavors.

Nice video Hmac.

I remember reading an interview with Paul from BCM and him discussing why he would choose an 11.5". Then also seeing where KAC's CQB is also an 11.5". I'm leaning towards an 11.5" but I've got plenty of time to decide.

That's the interview I read.

Has Noveske quit making 11.5"?

**Hmac** · 15 April 2014, 16:10

I don't recall that they ever did. I wouldn't be reluctant to go with a Noveske 10.5 upper. BCM has a good 11.5 inch upper and/or barrel.

I've had many of those moments, when trying to read anything on a 4" iPhone screen.

No worries. Actually I have a really excellent Noveske Light Recce as well as a couple of SBRs built with BCM barrels on Noveske matched uppers/lowers. Lots of confidence in both manufacturers.

Has anyone shot BCM's SS melonited 11.5"?

**GOST** · 15 April 2014, 19:23

Or is it ion bonded? I don't know, but anyone shot one?

I run an 11.5 SBR and have never had issues with performance or accuracy..I think you will do fine with the same length.
