View Full Version : Bushmaster 11.5in. Bbl. Entry Carbine
Any idea where I might find the technical specifications on the barrel diameter? I do not find them in a search on the manufacturer’s web site, a search here, or search on Google. I see it is a heavy barrel profile.

I have a BM 11.5 hbar with .870” OD under handguard, .750” at front sight housing & .730” at muzzle.
I am assuming the 'Bbl' stands for bull barrel (heavy barrel)?
Neg, two different barrel types, although similar & both are "heavy" with regard to weights. If you want 11.5" you might as well go with the light weight or gov't profile to save weight unless you're doing a lot of cyclic or sustained ROF. Check the below link for the differences.

Clarification- Bbl. is just barrel.
