just an update I tried the Benelli Nova extension as well as Stoeger neither one worked. Any suggestion or Ideas would be greatly appreciated

 

The Benelli Nova was what I was going to suggest. All those Turkish guns usually have the same threads. Be more specific on the issue. Is it threading on but not all the way or doesn't it thread on at all? I can tell you an 870 and 930 both have the same thread pattern but the 930 is deeper. If the 870 threads work but it was too shallow to thread down all the way, a 930 extension may work.

 

You do realize Stoeger doesn't have magazine extensions for their imported shotguns?

So.... Umm.... Did you just the magazine cap?

Not to be argumentative but I am pretty sure they do make magazine extensions for the stoegers.Yes it was the cap that I tried neither worked on the other

 

After speaking with Tri-Star customer service rep they stated that they could not tell me specifics for legal reasons but that the model I have is the newest model and has the same tube as the viper. They did tell me that the threads were the same but at the older models which I know will accept Rem 870 tubes. The only thing that I can think is maybe my mag tube is too long and needs to have some material removed so the extension can grab the threads. Is there any adverse effect to removing a 1/4-1/2inch of thefactory tube??

 

I have the same shotgun, let me know what you find out about the mag tube extension or any other things that work it would be good to know

 

this shotgun is made by khan/arthemis the previous gun was made by karl. if you look up khan shot guns you will see the identical shot gun. but it differs internally I think its a benelli clone it's bolt looks similar to the benelli m2 if not exactly the same

 

wow,

They really changed the gun didn't they? The pictures of your gun and the pictures of the original model raptor are so different that they are not even close. Different reciever, trigger , grip angle, grip/stock shape/comb, forearm, barrel... geez.. Them two guns are as different as they get.

 

Well I think they changed a lot of little things but no really huge changes the main one is the mag tube is completely different than the older models which from what I have read would take remington magazine extensions. This one will not the threads are different I dont know if that was done to keep folks from adding a tube or for another reason either way I have yet to find a tube that works.

 

Well according to this video, someone has had success using the remington 870 extension...

 

That Modification was to one of the older model Raptors that was mfg by Karl. That extension will not work with the Kahn/Arthemis model they now are offering and the OP has pictured.... I am chasing this goat around as well.

 

If you're still having problems finding an extension, King's Armory makes a 3 round for Escort pumps and semi's that also fit a Weatherby (all are Turkish made like your Raptor). Here's a link to my post in the forums here http://www.shotgunworld.com/bbs/viewtopic.php?f=7&t=395452

Alright, After finally receiving the extension from Kings Armory... (I chose the snailmail USPS Free shipping version - don't advise) The threads are perfect! I will, tonight make sure all is right and post some pictures.. But I think we have a workable +2 extension. I'll make it work and post results and any modifications I needed as soon as I can. Joey In Tech there was a huge help! THANKS NHShotty & JOEY!

King's Armory KA-LE01 KA-LE01 magazine extension





EDIT: Ok guys, Looks like I'm going to need to take about 1/8" off the magazine tube in order to make this work, but the threads are good match so I don't see any issues with this being a great fit. I am going to run another few boxes of shells through it before performing (altering) to make sure I don't have any warranty issues, that Tristar might reject should I perform prior, but, this extension will work with the minor modification. I'll post results in a week or so

Sorry for the delay. I Ended up not cutting the magazine. Lathed myself a small brass bushing exactly a 1/4" heigth 1" ID and 1-5/16 OD fit between the forestock and extension with about a 1/8 of a turn for tension and perfect alignment between the extension tube and magazine tube. worked like a top...new spring and voila 7+1 capacity. Test fired it yesterday and all is perfect with no alterations to the weapon.
