KT has this choke adapter for the KSG on sale for $44.80 (reg $56). I do not know if it will fit the KS7. It should fit if the threads are the same. If so, then you can use Winchoke tubes in the KS7. This is a Black Friday sale.

I checked the parts list for both the KSG and KS7. The barrel has the same part number (KSG-118) for both the KSG and the KS7. The threads at the muzzle end of the barrel should be the same since both the KSG barrel and the KS7 barrel have the same part number. I have noted in earlier posts that the KS7 does use some KSG parts as indicated on the KS7 parts list.

Cool, I'll give that a try then. Was going to get the rail while it was on sale, so may as well throw that and the wrench in the cart as well.

Do you think that adapter would work for the sico suppressor as well?

 

I don't know. I have no experience with suppressors. I live in Delaware and I'm not allowed to own such a dastardly device.

 

M*CARBO also has a choke adapter as well that fits remington instead of winchokes and Hi-Tec has one for remchokes too. I'd be curious to know if these fit as an earlier thread states when asked Kel-tec said their choke adpater did not fit the KS7. CARBO's choke adapter is only listed for the KSG though I see it listed for the KS7 from other sellers so it's hard to know if this is just a case of it hasn't been specifically tested or not.

 

AS I wrote before, both the KSG and the KS7 barrels have the same part number. That tells me that the threads on the muzzle are the same. I would think that if the choke adapter threads onto the barrel and butts up against the muzzle place any of the adapters should work on the KS7. The only problem may be the amount of clearance between edge of the adapter and the muzzle cap. This is not a problem on the KSG due to both muzzle nuts being off to the side. I have the Hi-Tech KS7 muzzle brake and it is different from the Hi-Tech KSG brake.

 

I've emailed Hi-Tech and M Carbo asking if their choke adapters will fit the KS7 or, if not, will they make one. I'll let you know.

 

As I thought, there is a clearance problem with the KS7. Chris at M*CARBO has asked if an adapter will work. This would just be a thread extension to clear the muzzle cap of the KS7 that would allow any KSG muzzle device to fit the KS7. Let me know your thoughts on an adapter for the KS7. Here is the reply Chris sent me:

Hi Mark,
I had a Great Thanksgiving. Hope you did too!

Unfortunately the KSG Choke adapter will not fit the KS7. I did add your name to the list to be notified. We have had a few requests for one.

Will keep you posted on this.

Would you be interested in an adapter that would make it fit? There is a clearance issue on the KS7 that is not present on the KSG. Otherwise the threads are exactly the same.

Thank You,

Chris Nelson

As I expected when the adapters were conspicuously missing from every place. Also, I'm not to thrilled with M*CARBO right now, I mailed them before I posted and I'm still waiting for a reply from them and Hitech. So much for replying to emails in the order they're received.

I wrote Chris at M*CARBO about asking for your opinion on an adapter for the KS7 that would allow the use of any KSG choke adapter or muzzle brake on the KS7. So, let me know what you think about such an adapter. Here is Chris's reply:

Awesome! Looking forward to what the reaction is. Yeah, that's what we were thinking as well....more options to use other muzzle devices.
Thank You,
Chris Nelson

I'd definitely be interested in an adapter, though if I actually purchase it or not depends on how it's executed. and given a choice between a KS7 choke adapter and a KSG one fitted over an adapter I'd take the former.

Folks, please write your thoughts on an adapter for the KS7. I need your opinions on this. So, good or bad, let me know.

Yikes this is a forum, not IRC. You've posted four times today already! Calm down. XD I promise you won't turn into a pumpkin or anything if you take a deep breath and just wait.

Adapter as in an extension to clear the clearance issue? I personally wouldn't be interested unless it kept the additional length very small. The ks7's appeal is in it's perceived shortness. Start adding a bunch of length on that and you're defeating the purpose of it.

My $00.02 anyway.

 

Nebraska, your opinion is always valuable. I took a close look at the muzzle of my KS7. I have a Hi-Tech Howitzer Muzzle brake on it. The threads on the end of the barrel stick out about 3/8". If you use an additional 1/4" for transition to the new threads and add the 3/8" for the threads you only get about an additional 5/8" to add to the length of the KS7 with a total length of the adapter of 1" (the first 3/8" of the adapter covers the existing threads and don't add to the total length). My measurement estimates may be close to what might be produced.

Well, I'd be willing to look at it if the length is around that 1/2" - 5/8" mark. Might be handy to have around even if it's not installed all the time. It'd be interesting to see what they come up with.

 

Got my Kel-Tec purchases before the KS7 has hit the FFL... :/

 

Hold on to the choke adapter if you ordered one. They say the adapter won't fit the KS7 but give it a try. You can always turn down the end of the adapter to fit the KS7. Or just return it.

So was it the Kel-Tec choke you picked up then? So what is the clearance problem exactly for the adapter? Is it just longer? Also Mark have you heard anything back from M*CARBO or Hitech? I still haven't heard back from them but I assume it's due to black friday madness. I would really like to hear more about this adapter or KS7 specific choke adapters. I'm really highly interested in being able to adjust the choke from say, home defense to trap shooting.

 

I don't know if Nebraska did get the KSG adapter but he did say he hasn't received his KS7 yet.

The clearance problem is in the design of the KSG vs the KS7. Both mag tubes on the KSG are set to the side of the barrel on the KSG while the mag tube on the KS7 is directly below the barrel on the KS7. This makes the mag tube of the KS7 a little closer to the barrel than the mag tubes on the KSG. Any KS7 accessory will have a smaller diameter at th muzzle threads than the same KSG accessory. While the choke adapter will fit the KSG clearing the mag tubes, the adapter will/may hit the mag tube and cap of the KS7 preventing installation.

The adapter that M*CARBO has proposed will move the thread portion of the barrel forward away from the mag cap so any KSG/KS7 accessory will fit the KS7 with a minimum of additional length added. M*CARBO is looking for interest in the adapter to see if it is warranted to produce. I have not yet heard back from Hi-Tech.

You will really turn some heads if you go trap shooting with the KS7. lol.

 

Ahh, I see I didn't realize that was the issue. Darn, that's really unfortunate but hopefully it doesn't mean we won't see a dedicated ks7 adapter.

And yeah I might get some looks but I've seen some promising video of trap shooting with a ksg. I'm sure the ks7 will do better thanks to its higher carry handle sight, which looks similar to blade sights I saw posted for the ksg.

I'm not looking to compete I just want to find some fun ways to practice and shooting clays sounds like a lot of fun. I am just as interested in the choke for home defense purposes as well so it's a win win.

 

Shooting trap or skeet is a great way to just have fun while learning the operation of the KS7.

 

Here's a thought. Is it possible to drill and tap a KS7 barrel for screw-in chokes? I don't know if the barrel is thick enough to do this. That would keep the length the same and allow for the installation of a muzzle brake while still using the screw-in choke tube.

Edit: Will someone measure their inside barrel diameter and the outside diameter at the muzzle of their KS7? I have a muzzle brake on mine so I cannot at this time.

 

Wouldn't a caliper be the best way? I mean I don't have one but maybe Nebraska does? I assume the nut has to come off first, right?

 

I do think that the barrel nut would have to come off to cut the barrel for the screw-in choke. One potential problem is the depth of the threads at the muzzle. That may make the barrel too thin to drill for a screw-in choke. While I do have a muzzle brake installed on my KS7, I did measure the inside diameter of the barrel nut which gives an idea of the diameter of the barrel less the threads. The nut measured 0903".

On 4/22/11 on the Trapshooter.com forum shotgun52 wrote, in part, the following minimum outside barrel diameter and maximum bore diameter to install different screw-in chokes.

12 Ga • Rem/Inv .845, .736

12 Ga • True Tube .825, .736

12 Ga • Thin Wall .805, .730

12 Ga • Soldered Sleeve .820, .740

As long as the measurements of the KS7 barrel fall within these ranges, accounting for the depth of the threads, then it should be feasible to drill the KS7 barrel for a screw-in choke.

Just a safety reminder: Don't use slugs in a full choke, and possibly a modified barrel. You could blow the barrel and damage the shotgun and/or yourself.

 

Finally got a mail back from M*CARBO. Not hearing anything about an adapter from them but they are saying that the KSG choke adapter will fit if you just make a small cutout into the magazine nut.

 

True. I was told that but you have to remove any muzzle attachment before you can take off the mag cap if you do this.

 

Update: I asked my gunsmith if a screw-in choke could be installed in my KS7. He measured the bore diameter at 0.748". The maximum diameter to safely install a screw-in choke is 0.736". So, a screw-in choke CANNOT be safely installed in a KS7 (mine anyway). I will keep my muzzle brake and factory cylinder bore.

 

True. I was told that but you have to remove any muzzle attachment before you can take off the mag cap if you do this.

Well, talking with M*CARBO I'm not hearing much about any adapter. The person I'm speaking to doesn't seem to know what I'm talking about and I've tried to ask them three times now and they keep mis-understanding me, thinking I'm taking about a mag cap or a those silly spikes they sell. It's getting rather frustrating.

I am debating just getting the magazine cap altered. How often do you expect to take it off?
