The BM 16" lightweight barrel looks to have a slightly larger barrel diameter right where the FS attaches. If I wanted to have it cut down and a Vortex FS pinned to make a 16" OAL, would the thinner diameter at the new cut be a problem? Has anyone had this done?

It is not fatter at the tip. If it was the front sight base could not slip over the muzzle of the barrel. Barrels can get smaller after the front sight base but not larger. You would have no issues with the Vortex on a 14.5" cut down superlight.

The Bushy superlightweight pre-ban barrels do have a very small increase in diameter under the front sight tower and behind the threads at the muzzle (for the crush washer to butt up against). Bushmaster has stated in the past that the 16" SLW barrel can't be cut to 14.5" because the profile is too narrow to attach a conventional washer & flash hider. *Conventional* being the key word there. Luckystiff sent a 16" Colt to KKF and had this very thing done. Kudos to KKF!

Didnt know that, thanks. Is the larger end of the barrel the same size as under the front sight base? Anyone have a close up of the larger area at the muzzle? I never noticed it.

Probably, but would need to mic it to be sure. It's sort of visible in the pic at bushmaster.com: [img]http://www.bushmaster.com/shopping/barrel-assemblies/Images/abbl-16sla.jpg[/img] The post-ban barrels do seem to be the same diameter from the front sight to the muzzle.

Anyone had KKF cut a BM?
