I have a 20" A2 built from an Olympic lower & parts kit from Model 1 during the Clinton years. Now that the ban is gone I want a threaded muzzle, flashider & bayonet lug. My barrel has a welded brake on it currently. What is the best method to accomplish this? A new complete upper is obviously the easiest & most expensive proposition. I could replace the barrel, but this becomes expensive quickly when I have to buy all the tools, action blocks, etc to do it right, and there is nothing wrong with the current barrel. Is there somebody out there who can cut off the brake, recrown & thread the barrel for a small fee?
Thoughts are appreciated.

Just about any gunsmith could do it. If memory serves me its 1/2X28 fine thred. Good gunsmith will also be able to pull the front sight and replace it with a stand. Miltary one with bayo lug. Parts about $50 labor less than 1 hour?

I've never had work like this done myself....but I've seen ADCO come up quite a bit when talking about similar stuff.

ADCO gets a lot of praise here and they are who I got my complete RRA upper from. I will definately buy from them again.

I'm sure others with more experience will chime in. Good luck!!

If your 20" barrel has the perm brake on it, then the smith will have to cut it down shorter than 20" to get it off. Then he'll re-crown and thread the 18-19" remaining barrel. It won't be "perfect", but it'll be close enough. In fact, a lot of folks are starting to play around with 18" barrels, so maybe you'll be "cutting edge!"

Another plus 1 for ADCO. If you send it to them for the work the post office will have it longet than they will.

ADCO fixed my post-ban for me. They do good work and have good prices as well.

Mine is on it's way back to me from ADCO. I'll post before and after HI-RES pics of the quality.
