Bushmaster ACR barrels about to drop?

The new Bushmaster catalog is listing (3) new barrels for the 5.56 rifle and (4) new barrels for the up and coming 6.8 SPC rifles on page 59.

New ACR barrels
The 5.56 barrels will be available in 10.5", 14.5", 16.5" and 18.5".  The new barrels do not have the M4 style profile and appear to have a slightly smaller diameter.  This promises to improve the balance of the ACR rifles by reducing the forward weight of the rifle.  The 10.5" and 14.5" barrels will feature 1/7" barrels with AAC Blackout flash suppressors (non-suppressor model) while the 16.5" will feature a 1/7" twist and a suppressor mountable AAC 51T flash suppressor.

The 6.8 SPC barrels will be offered in 10.5", 14.5", 16.5" and 18.5" lengths.  No mention is made of the rifling twist rate.  The 6.8 SPC barrels will all feature A2 style birdcage flash suppressors.

I'm looking forward to the release of these barrels in 2012 so I can finally SBR one of my ACR's.  I guess I better get that paperwork started now.


  1. too bad they aren't coming out with a new firing pin... go back to steel

  2. All you need is aac blackout and you're good to go. It would be nice to have an 18.5'' barrel though.

  3. it would be great if they made a barrel 18.6 inches or bigger due to retarded Canadian laws.

    1. Just get the 18.5" barrel and have your local gunsmith permanently attach a longer-than-standard muzzle device (Like the BC1.5 from BattleComp Enterprise or the PWS FSC556, which I believe is quite long) Should do the trick (At least, it does in the 'States.)

    2. It only has to be 18.5 inches. It cannot be LESS than 18.5 or 470mm according to section 84(1) to maintain non-restricted class. But yes too bad its not made for 223. I havent even seen 6.8 SPC ammo in Canada. I am sure its here, just not that common.

  4. I know it's been a while, but has anyone actually been able to buy one of these barrels yet?
