Look up my channel on YouTube under username "ebenjamin23" and I have slow motion video of it being shot along with some other guns.

Looks like a great build. How's she shoot?
How's that thorsdon's pistol kit and cca saddle work with the kak pistol buffer tube? Any issues with rotation and not staying in place? I thought you "had to use" a carbine buffer to keep it from moving around. |

Here's a link to slow motion video of me shooting it.
https://www.youtube.com/channel/UC0g1A6I13Wwyg2taRcy60ow Honestly, It shoots like a rifle. The Thordsen/KAK combination gives me a very similar LOP to the rest of my ARs and works just like you want it too. The kit is actually made up of 3 parts: The CAA saddle, Thordsen's buffer tube cover and Thordsen's saddle mounting kit. The buffer tube cover mounts very securely and is a solid base for the rest to mount to. It is really a great solution and a viable alternative to the Sig Brace. The Thordsen kit mounts up very securely to the KAK tube and does not move at all. I wrapped the tube underneath the saddle in electrical tape, based on some other experiences online, and I have experienced zero movement. I have not used the Sig Brace but the look alone was enough to sway me towards this set up. I am very satisfied with it and would not hesitate to purchase this set-up again. |

What is the handstop looking deal the sling is attached to at the rear o the saddle in the 2nd pic?
|
|
It's a QD sling mount.
I got the idea from a post on here. http://www.ar15.com/forums/t_3_122/642931_Possible_solution_to_a_problem_AR_pistol_owners_face_.html |

If I was going to use tape it would have been friction tape as it has grip and doesn't easily turn into a gooey mess as electrical tape often does.
|
|
Friction tape would add too much girth. It is a surprisingly tight tolerance but allows enough room for one pass with electrical tape.
I use high quality electrical tape and I don't plan to remove this set up so I don't see this being an issue for me. |
|
You're braver than me. I wouldn't add the sling mount like on a pistol until ATF gives a response on it. Way too much chance of them deciding that's the line between stuff on the back of a pistol and a stock.
|
|
I'm not that brave, I took it off after the pictures. At least until the ruling comes back.

Thanks for posting this thread. I normally shoot NTCH but the thordsen/carbine buffer tube combo was just a bit short for me.
I took my pistol apart and replaced the carbine tube with a pistol tube and got that little extra LOP I wanted. |
|
If Ihadnt bought an SB15 I would have bought the Thordsen kit. Looks very solid. Nice work.
|
|
What were you using before the KAK tube if I might ask? I really like the look of that I may have to do something like this on my next pistol build.
|

He's using a standard buffer tube, that's what the Thordson is designed to use

Quoted: Love that dust cover, is it custom made? View Quote Yes it is. I get them from http://www.tacticalgearjunkie.com/ They are easy to deal with and can put pretty much any image on there. It just adds something personal to the gun. They did this one for the girlfriend. She loves it and you'll never mistake it for your rifle. Yes, that says, "Craft With Cats". |

If I can help somebody build what they really want by showing how I did it, then I consider it a win. I found very little information on using this set-up online and I got very little help from the manufactures when I emailed them for tube O.D. and general information on compatibility. Thorsden did say that they are working on a similar kit that will be available at some point in the future. |

I bought the buffer tube offered by Thorsden that is basically a standard adjustable buffer tube without the adjustment holes drilled in it (It's for sale. If you want it, email or PM me.) In my opinion, the Thorsden kit looks best right up against the receiver, as intended, but I could barely shoot it like that so aesthetics had to take a back seat to useability in this case. |

I am doing a second pistol build with a 10.5 barrel and was thinking about using a standard buffer tube that I have lying around but want to be able to use a VFG at times. I am asuming that your OAL with the standard buffer tube was under 26"? Sorry to kind of hijack your thread but it seems like a waste to post this question in a new thread.

View Quote I didn't actually measure mine at all points in the process but I am currently at roughly 27 1/2" with the final set-up (Using the KAK tube). The KAK tube adds about 1 3/8'' from the back of the castle nut to the "shoulder" where the Thorsden cover sits. |

Where do I get the rail and the sling mount you mounted under the Thorsden or whatever?
thanks |

You can get the handstops on amazon or you can get cheap ones from air soft sites. |

Can someone show in more detail how this would mount up to a kak pistol buffer tube securely? Is it wedged on like a sig brace would be?

I like it! I am thinking about going this same route with my next build. Any info. on how the standard setup vs the kak setup compare in length to an a collapsible stock?

I like what you have done here. Very cool and functional from the looks of it.
Did you need to use the CAA Saddle adapter kit from Thordsen for this set up, or did you get away with out it? Truth is not sure what the adapter kit does - not a ton of info from Thordsen. |

Quoted: Yes, the adapter kit includes two very important polymer pieces that lock into grooves in the Thordsen's buffer cover, filling a small gap and allowing the CAA to secure up rock solid with the buffer cover. Maybe you can see it better in these pics...(you can't see the internal components, just the sling loop pieces.) Hope this helps! http://i433.photobucket.com/albums/qq58/awesomedave_bucket/IMG_0263.jpg http://i433.photobucket.com/albums/qq58/awesomedave_bucket/IMG_0264.jpg View Quote View All Quotes View All Quotes Quoted: Quoted: I like what you have done here.

Wonderful! Thank you for the response! hard to tell some times if the extra bits and pieces are really necessary or suggested. I'm ordering up tonight.

Better have a look at the link you referenced. It's been updated with a reply from the ATF. That combo of parts is considered "problematic". Something about a "substantial vertical surface" being similar to a stock, which on a pistol makes it NFA. Oops.
I'm using a rubber crutch tip over a Spike's buffer tube. The rubber keeps it from sliding around when you shoulder it, or slipping if you lean it up against a wall. Yeah, it looks cheap , but it works great. And it's not a stock. |

Do you think this set up would work on a PSA Pistol tube, the way it is "fluted"?
|

It might rotate on a round buffer tube, the Thordsen kit is made for a regular buffer tube or their pistol buffer tube that isn't indexed for a rifle stock. I think the recent ATF letter was not addressing the Thordsen kit, but with someone who added an additional rail piece to the BATF approved parts which did make the contact area with your shoulder larger. They specify in that letter that the modification is creating a larger surface area similar to a rifle butt stock, whereas the parts included in the Thordsen kits if you don't modify them have a much smaller contact area. It has a smaller footprint than a Sig brace for sure out of the box, but it does have a better cheek weld which is OK per the BATF. I have both and find the Thordsen kit to be more comfortable and better looking, but the Sig brace is still a great and useful product that I applaud them for creating. My hats off to both companies for their solutions, while not for everyone, you will see tons of great examples using both on the AR pistol pic thread, close to 150 pages and going strong!
