CONSTRUCTION PROCESS – Final Assembly


To join the now modified AirTech recoil pad to the adapter plate, I mounted the adapter plate into the butt stock. I then distributed some super glue to key places on the adapter plate and then placed the recoil pad against the adapter plate. (See the image.) The super glue allows you a few seconds to get everything aligned for fit to the butt stock.



After a short time, the super glue is set, and the entire assembly can be removed from the butt stock.

To make sure the recoil pad will not separate from the adapter plate, I added a few aluminum 1/8” pop rivets to secure everything. The pop rivets turned out to work quite well.



The two rivets that are side-by-side are ½ inch grip length, whereas the others are 3/8” grip range. I chose the grip range based on how the drill felt as it went through the base material of the recoil pad. The finished KSG ready AirTech Recoil pad is shown below:





Here are close-ups of the top and bottom ends of the recoil pad installation showing the final fit:





And, of course, the final installation looks like this at a short standoff distance:



A comparison of the AirTech, the extended, and the standard recoil pads is shown below:



FINAL THOUGHTS

The need for the “window” to accommodate the “Lifter” mechanism was the most challenging part of the project. That was an iteration of cut and fit tries using manila file card stock. Once that was complete, the knowledge was transferred to ABS sheet material. It seems that a person having skills creating things with a 3D printer could easily create the adapter plate in one piece. Fitting the Limbsaver AirTech Precision-fit Recoil Pad to such an adapter plate would be well within the skills of many KSG owners.

TEMPLATES ATTACHED

To make it easy for the Do-it-yourselfers out there to duplicate the construction of an adapter plate, I have photocopied three templates to a PDF file and attached it to the Part 1 post. [Be sure to set the PDF to print at "Actual Size"] There is a template for the recoil pad modification (window location), the baseplate, and the filler plate. You probably won’t need the filler plate template, but it is there anyway. You could cut out the paper templates and attach them to your ABS plastic sheet material with removable double sided tape. [can be found at any office supply place and places like Walmart.]

I discovered in the final fit-up that the window needed to be extended toward the bottom end of the recoil pad by about a 1/16th to 1/8th of an inch. With a Dremel Tool, this is not a great challenge.

For the nominal cost of the ABS plastic sheets, you can construct your own adapter plate and have a nice recoil pad installation. If you don’t have a Dremel Tool, this is a great excuse to get one. They are incredibly useful!

For convenience, I also attached a PDF of Parts 1 and 2 to the Part 1 post.

Looks pretty badass! Any update on wear after running some rounds through it? And what type of rounds do you typically use? Any thoughts on selling this as a product?

I am a volunteer Range Safety Officer at the local public shooting range. Because of the virus situation, the range has been closed and I have not been able to give it a field test.

I would note that the super glue that was used towards the end steps was just for holding things in place where they are needed to be so that I could drill the holes and insert the rivets. The way it is constructed, I expect that you would have to club it pretty hard with a hammer to break it!

At the range, I have used trap loads (2-3/4") and some slugs (2-3/4). The slugs, particularly, convinced me I needed a pad. For the most part, however, I have been using the mini-shells, which the KSG is quite happy with. [My choice for home defense - buck shot in one side and slugs in the other.) Even the slugs in that size won't destroy your shoulder without a pad, but a pad is nice.

As to manufacturing and selling: What I put together is fairly easy to do if you have a Dremel tool and a few other hand tools, so I see it as a DIY project. The biggest challenge was coming up with the template and I have included the file for a paper template.

That being said, if I did 3D printing (and of course knew what I was doing with that equipment!), I think it would be quite easy to produce the adapter plate, which is what one would need to make it a worthwhile production project. The adapter plate is where all the work really is. Once you have the adapter plate, you can use it to attach anything to the rifle butt. But alas, I am not in the 3D world.

I can’t wait to try mine out at the range this week!! Thanks for doing the hard part and figuring this out, LenC

That looks really good! How much of a challenge did you find it to be to make the adapter plate? How long do you figure it took you to do this from start to finish? Which AirTech pad did you use?

I am excited that someone else has tried this!

Subtracting the TWO times I had to take my dremel apart to repair it I’d say it probably took me about 4 hours or so. Now that I’m familiar with how it all work I’d probably be able to bang one out in maybe 3 hours. I used the same pad you used. I bought everything using the links and info you provided, printed out your instructions and template, and went to work! I guess the only thing I did a little different was that I didnt use super glue to hold everything together and then rivet for final assembly. I used the PVC cement, just being careful not to get it on the weapon itself and then used a few plastic rivets to help secure it a bit more.

Thanks for the info - I spent far more than 3 hours getting to the final template! I am glad to hear that the PDF template was usable. How did you attach it to the ABS sheet?
Oh I’m sure. I know that would've taken me forever!

Looks awesome. Since i am inherently lazy, has anyone tried to make the 10810 w/adapter kit work?

I used the Model 10802 as it seemed to be a close fit, but several others might be workable. Models 10801, 10806, 10808, 10814 are within a few 32nds of an inch in either length or width of the Model 10802.

That being said, the general approach that I used could probably be used with the 10810 that you are asking about, but the 10810 dimensions are significantly larger in both directions than the other models that I have mentioned. Here are templates for both the 10802 and the 10810 (from the Limbsaver website)

10802


10810


So, using the 10810 you are going to have more noticeable overhang of the Limbsaver pad. Also, the adapter piece will be a discard, as you will not use it. Remember, you are going to have to remove some material from the pad's base plate to accommodate the lifter.

If you already have the 10810 go ahead and try it.

Thanks. I couldnt find these to actually compare dimensions. My thought was more around the adapter than anything. I guess I will just have to give it a try.
by the way, I am a single dad locked down w two kids so i do not have much time these days for dyi project. If someone is making the adapter for sale, please let me know. Thank you.
I am still planning on making the limbsaver adapter that I was talking about in another thread last year. Have the material cut, most of the design work done, and all the tooling purchased. Hopefully will have something made soon. It will use the limbsaver 10201 or 10809.
Anyone try this?
They are the beat recoil pads for the ks7. I beta tested on the ks7 yeara back. I have never looked back. High quality and they deliver the goods regarding recoil mitigation. Heads and shoulders above kel tec product or any thing else being offered. JMHO.

Just bought one right now. Greg does great work. Looking forward to getting it.
