Swapped for a neat little 20 gauge pump yesterday, an EAA made by Akkar.

I intend to murder a few innocent clay pigeons with this thing, and will want to end up with a skeet choke on the gun.

It came with a zombie-apocalypse choke tube, complete with a serrated end suitable for dispatching an alien creature after you run dry of ammo. There are no markings on the choke. What is the proper method to measure this choke? No sense in buying a choke if this one is already the right size, with a bonus of raised highbrows at the skeet range.

Looks like you might be able to unscrew the off-set nosepiece. I should think you'll have to to get in there with other than a proper choke gage. Does it have no single stamp anywhere on it?

Generally when I see those I think of off-sets fro stabilizing against wood for Lock-Busters and like shotgun ammo. Though, I don't know how many outfits blow hinges and locks with 20s - seem likely up to it.

In any case, I'd keep running with Z.A. dispatch tool.:thumbup:

Unfortunately the choke is one piece and no marks that I recognize as such. Am assuming that calipers would need to go in the muzzle end, and the tacticool bit will get in the way of that.
 
How about grabbing down a table from the internet and seeing if you can't use elimination with cylindrical objects that you might have around the house.

Also, throw a six-pack in your car and find a machine shop that'll slide a bore gage into it. I've met some interesting folk just about that way.

Being a breaching extension, I'd be surprised if it was not Improved Cylinder.

What the choke inside measures doesn't mean anything if you do not know the bore diameter. The best way to tell is to hit the pattern plate

^^^ This. The measurements on a choke are indicators of what type of pattern it SHOULD throw, but no guarantee as each gun is subject to shooting looser or tighter than the choke spec would have one think, and more importantly, may or may not have holes in the pattern, POA and POI may not match, etc. Pattern it.

And pattern it with the exact loads that you will be shooting when success matters. You can change a pattern very significantly by changing wads, shot size, shot weight, and muzzle velocity. Some or all of these variables will change when you switch loads, so pattern each load that you will shoot when it counts.

What George P and I6turbo said. It's always fun to raise eyebrows at my trap club. We're there to have fun and even if something new doesn't work out, if you had a good time discovering that, the round was a success.
