I recently bought a used 10/22 equipped with a bull-barrel by Numrich, threaded 1/2x28. I bought it mostly because it was already threaded, and it was stupid cheap. I wanted another host for my TAC65. The barrel had an A2 flash hider, of all things, threaded onto the end when I got it. When I took it off, I noticed the threads seemed a bit long. I thought the rule was something around .400. My can threads on, but I stopped when it started to get toward the shoulder. I don't like the feel. You can see from the photos the threads protrude through the end of my TI thread protector. I'm guessing the thread protrusion is the "excess."
The barrel is long enough to lose the excess. So here's the question. Do I ignore it? Have the threads machined off? Use a washer to space it? If I go the washer route, any idea where I can find a .920 washer to drop in? Thanks for the advice. |

If the threads lock up to the shoulder of the barrel threads then don't sweat it.
If the baffles hit before the can shoulders up, then have a shop recrown the barrel. Don't do washers as that's looking for trouble. If crud or dirt gets up under the washer, it could lead to a baffle strike in my opinion. I have a threaded handgun barrel around .620 long and it works just fine in my AAC Element. Like you I didn't like the looks of it, but it works fine. |
| If you don't either chop it or use a spacer you will have problems going from the .40" threads to the longer threads, unless you completely clean them first. I almost got my SWR Spectre stuck on a ER Shaw 10/22 barrel after only shooting 20-30 rounds with it on my Tac-Sol Browning Buckmark. |
