I have stumbled onto a free 450 bushmaster barrel. The crown of the barrel is damaged (someone fired a round through it when the bore sighter was still in place). So I thought of having ADCO cut down the barrel to roughly 11" (just forward of the gas block) and then see if Noveske or PWS will make one of the KX flash suppressors to build appropriate back pressure to keep it cycling.
This sounds like a neat project but can someone give me the ins and outs of what this might do to round performance. Understandably, the round will move slower because of the shorter barrel, I'm just wondering if this is even worth it.
The cost of doing this is literally around $300. I just figured it was worth it to have something unique.
Thanks in advance for the input
