I just purchased a Khan Arms A-Tac Venator on GunBroker for $189 new in box.

I understand that due to importation, the magazine tube had to be crimped that limits the capacity to five 2 3/4" or four 3" shells. From my understanding, the magazine tube that extends beyond the magazine nut is inaccessible/empty.
Allowing this space to be used could increase the capacity by at lease two shells.

There's very little information about this particular model out there currently and I couldn't find the answer to my question concerning modification.

I read that the crimp is, most unfortunately, on the wrong side of the threads to allow a simple replacement.

Does anyone know if there's a way to remove/reverse the crimp without significantly weakening the strength of the magazine tube?

I'll continue my search and will include any solutions I might find here, however if anyone has any ideas, I'd love to hear them.

A better picture would help.

Also consider that the spring needs somewhere to go when loaded.

Good point. I believe for domestic use in Turkey, these tubes are not crimped. I'm hoping this means the follower and spring are the same as those they export to the US. If so, simply removing the crimp, if possible, might be a viable solution.

I'm looking to see if there's a parts diagram on online to help assess what options exist. So far I'm not finding much.
 
well.....if I was willing to ruin it, and depending on the crimp, id probably take the tube off, heat the crimped area and run some sort of expander thru it. I've used sockets to take dents out of the front of a shotgun barrel, Dono if it would work there.

failing that cut and weld on a new extension.

Good info. A diagram is less useful than a picture.

As @LoonWulf says, what's been crimped can be expanded. . . with some risk. An appropriately sized mandrel, gentle taper, good swaging lube, and heat, will probably iron out the crimp. Your results may vary.

Buying an uncrimped part might be easier if you can find an importer.
 
Is the crimp just a dimple in the side of the tube or is it crimped like a ring all the way around the tube? I agree a picture is worth a lot to those of us trying to answer your question.

I have seen the dimple removed easily by just drilling a small hole in the side of the tube where the dimple exists thereby removing it. The small hole doesn't hurt anything and doesn't affect the operations other than allowing the shells to pass by easily.
 
I did the same thing as Loon Wulf. I got a Winchester 97 years ago that had a dent in the tube, limiting it's capacity. I used a socket just slightly smaller than the inside of the tube, and something to push it with some force. It took that dent out easily, and I have to look closely to even see what little is left of the dent. Let us know how things work out for you.
 
I don't know how your gun compares to a Remington 1100/1187 but HR Funk has a YouTube video about converting one to a tactical configuration. He removes dimple in the video. You might find it useful.
 
IF the crimp is like the 870/1100/11-87's, this is the procedure:



JD knows his Remingtons; he is a factory trained Armorer. (He can't spell very well, though...;))
 
With respect, I suggest running a few boxes of shells through the gun before investing any time in this procedure. There may be other smithing required. I have only seen and handled the abomination they had the gall to call an over/under shotgun, three of them in fact. They were ill-considered purchases for a gun club youth program. Two of them never fired a shot and were disposed of thusly with broken extractors and appalling friend latches. The first one doubled religiously with every three out of five trigger pulls. And then the forearm fell off.

Hopefully, you have a different experience.
 
I haven't the chance to fire mine yet (voluntarily pulling 12 hour days 7 days a week for the past 3 months for the OT & surge pay).

I did inspect the magazine tube the other day and it appeared (I hope I'm mistaken) that the diameter of the tube is smaller after the crimp.

I may just keep it like it is, accepting it as a 5 +1 2 3/4" or 4 +1 3" shotgun, and buy a Mossberg 930 as I originally intended.
