As stated, there are muzzle devices out there that will still allow you to cut back this barrel without having to register it as an SBR. The Noveske KX3, the PWS CQB Comp, the LeVang linear comp...I believe any of these would allow you to cut the barrel back far enough to remove your new hole.

Thanks for the responses. I do live in KS and I probably shouldn't have been a tight wad and just SBR'd it. I was trying to avoid extra expenses. I called a reputable gun shop in North Kansas City and spoke with them about it. On their advice I bought some lapping compound and will make sure the entry wound is free of any burrs and then I will pin the break and weld it. I fired 30 rounds through the rifle today and it cycled fine. It even has a test Osprey piston in it and there was no noticeable degradation in gas pressure to cycle the action. It was interesting to feel the jet of gas on my legs when I was firing seated unsupported though. I wonder if there is a loss of velocity with gas being ported off at the muzzle? With unzeroed sights at 25 meters I was getting standard sized (for me) groups. Thanks again for the help and I think I will pick up another barrel or two from BCM, just in case. Thats a good point.
Glad to hear it still functions, but I hope you aren't shooting this on a non-SBR lower...
I think I would be figuring out how to make it legal while cutting it back far enough to remove the hole, like jsebens suggested. You're flirting with disaster if you don't.
I think the barrel is toast at it's current length. I'm certain this will play hell on the accuracy. I'd make a 10.5" or 12.5" out of it.
Here's how I do perm. attached flash hiders:
Drill the flash hider at 6 o'clock all by it self on a milling machine with a 1/8th drill.
Install on the barrel and index properly.
Dimple the barrel through the flash hider on the mill with the same drill.
Cut a segment of 1/8" pin and then TIG weld the pin in place.
Clean down the slag and cold blue with G96 cold blue.

I vote to give it a shot. What the hell do you have to lose at this point? Worse case you lost some accuracy learned a lesson and moved on. Best case is you are fine. Debur the hole if you can.
It seems to me that cutting down and recrowning the bbl would be a lot more expense and more likely to cause problems if not done properly.
It seems that you were trying to avoid a tax stamp in the first place. Your choice of course. If I had the option I would sbr anyways.
The most important lesson here is to always learn and practice on the cheap stuff![]()

I'll pay you $50 for it. I plan to cut it down and SBR it.
