Threading a barrel for chokes

[coonhunter]

Hey guys looking for advice.  I was wanting to buy a single shot 20 ha to set up as a light turkey rig.  Then I realized I have a magtech 20 in the safe that I don't use anymore.  It has a fixed modified choke. What your thoughts on threading it for chokes?  I was thinking maybe rem choke threads?  Also who would you recommend do the work?  The gun is in great shape and has a walnut stock. Super light as well.  Thanks!

I've had this done on multiple occasions, so first consideration is the cost and secondly is value of sale if you decide to get rid of it for whatever reason. On average, I spent $250 on modifications to the gun, so going in that's roughly what you're looking at. Of course there are variables to that number but that'll give you a ballpark figure to budget with. All of my projects included cutting the barrel down in length and threading for chokes. Any company you choose can tell you what barrel dimensions are needed to have it threaded and for what particular thread pattern. I recommend that you have it done in the thread pattern that you have chokes for already, obvious choice. While they have your barrel ask them to lengthen the forcing cone. Then you'll need to decide on sights or optic rail. Any cosmetic changes will of course add dramatically to the overall price. As far as who can do this type of work, well, there are several companies that come to mind, some of which advertise here on this forum. When the gun is all finished you will have a dedicated 100% turkey thumper! Have fun and please keep me in the loop.

Only thread it if you can get remchoke, invector or another popular thread pattern. Don't get TruChoke threads as you will not have a lot of options for trying/trading chokes. Better off to save that gun for something else or trade it for another gun already threaded in a popular pattern. I know from experience. Google Mike Orlen in Massachusetts for a good job done quick and reasonable.

I figure if I go tru-choke, I will send it to sumtoy. And get one of his chokes. I plan it to be a dedicated turkey gun anyway.  I have plenty of other shot guns for other uses. I also looked and can get Carlson chokes pretty easy in tru-choke threads.

I had Mike Orlen cut and thread a single shot 20 gauge that was a fixed full that just wouldn't pattern for me.  I sent him a carlsons .575 choke that had winchoke threads and for about $100 bucks I had it back in less than 2 weeks.  Gun patterns great now, no complaints!

Compnchoke makes them in thinwall truchoke. They recommend theirs in a .655 for barrels shorter than 21". I have one in my A5 Mag and it loves LB 3"x6's. 
Edit: I had Carlson's do my A5 barrel and now have 4 of their chokes, 650, 660, 665 and 670. The Compnchoke out shot them all.
