I wanted a stock pad and recoil buffer for my new .40sw Kel-Tec Sub 2000.

So after a brainstorm last night I went to Lowes today and bought a foot of 1" ID/1 3/8" OD Dishwasher discharge hose. I bought it on the way to the range so I waited until tonight to fab it up.

Here's how it turned out.

Rough cutout for the charging handle

Then I made the recoil buffer out of some scrap

http://i741.photobucket.com/albums/xx51/toshbar/CIMG4003.jpg

It fits into the stock tube in front of the plastic end piece and the bolt assembly hits this rubber instead of hitting the plastic stock cap or the charging handle hitting the back of the cutout in the stock tube.
This shows how it goes in. when seated, it is about an inch into the tube and is easily removed by pushing it out with the bolt.

This is how far back the bolt goes before hitting the tube. About 1/4" before it did before. I can cut the buffer to all different widths very easily.

I haven't tested it yet, so I may need to modify the buffer and make it go around the spring more, or make two halves, or possibly just get some 1" OD tubing and cut it to length to slide in there. I may make a few different width ones to see which one works best. With the one in there now, the bolt will lock back, but it takes some force to compress my buffer so the charging handle can rotate enough to lock into the slot.

I still have half of the tubing left over so I could redo it and try to get some cleaner cuts, but I think this will work well for now. Cheek weld is a lot more comfortable and noticeably more grippy.


Total cost was $2.88. http://www.glocktalk.com/forums/images/smilies/wavey%5B1%5D.gif

Good thinking.

I went a different route. I bought a sheet of self-adhesive neoprene (sold in the archery section for bow grips) and cut a piece to fit the tube. Plenty left for a second "pad" should this one wear out.

You can use the little rubber washers for garden hoses for the buffer also.

This was my original plan but then I had the idea to have the charging handle hit the rubber that wraps around the rear of the stock tube. When I had a small section leftover my design morphed.

I made another buffer about twice as deep as the one pictured that totally wraps around the spring.

I'll update when I get a chance to test it.

Update on this whole thing:

Both parts work very well. I am very pleased with my $3/1 hour investment into it. The pad does raise your cheek a bit and my head has to rotate a little more than normal to center my eye in the rear aperture, but it is very doable. I did back to back testing with and without the bolt buffer, and it does reduce the impulse of the recoil. It is more of a movement back into the shoulder than a complete shock loading and snap that it was before.

Nice job toshbar...

I just love my subbie as well!!!

Here is the recoil buffer that I made for my subbie...

I tried it out today and was very happy with it. I machined the buffer out of 90A urethane...

As far as a butt stock recoil pad, I added this to my 1" extension...

The blue "thing" is a coated cable for a sling point..The black "thing" is a cable tie for another sling point on the forearm..Cheap but effective...

Maybe these older pic might explain..Woops , replaced the rear cable tie with the coated cable..

I have never shot one of these, but I'm definitely interested... I'm just wondering why you need a recoil pad for shooting a pistol cartridge out of a rifle? Seems like these things wouldn't recoil much more than a 10/22.

You really don't on the 9mm version, very light recoil...

Lol. $510.

It's a sharp recoil as the bolt comes back since it's complete blowback with about a 2lb. counterweight attached to the bolt.

What with the short stock and having trouble getting a good sight picture , due to the height of the sight's, you can get "stung" with the recoil of the 40 cal..Here is a pic after shooting around a hundred rds..It was warm and I wasn't wearing a shirt..BTW, I don't bruise easily...

The 40 definitely has more recoil than the 9mm. An internal recoil buffer on the 40 is a good thing, the 9 really doesn't need it (IMHO).

{S. That is some nasty recoil rash

HMMMMM....... So that's what those bruises were from Saturday when I ran 400 rounds through my Subby.......


I thought it was odd to be bruised after 20 or so rounds through my Garand, which never bruised me before....

Now I know! :cow:

I should add, that this was my first attempt to shoot the Subby with my new trifocal eyeglasses...I was shifting the butt stock to different positions trying to get a good sight picture..I have come to the conclusion that trifocals and shooting the Subby are not the best combination..Bifocals may be the answer..

Tonight I put an AK front sight block on my subby:

http://i741.photobucket.com/albums/xx51/toshbar/CIMG4144.jpg
Ripped the factory front sight off, kept the knurled bushing on. Put the bushing up to the bench grinder while still on the barrel until the AK FSB would slide over to the right depth to align with the folding latch(last photo). Then drilled and tapped a hole for the setscrew, lathered it up in some paint, and then some loc-tite and eyeballed it to get it close to zeroed. Haven't fired it yet, but am anticipating having to drill a lower hole in the rear sight because the AK post is ~1/8" lower than the kel-tec post at this time. I may be able to raise it up even with the front sight ears and get it to work.

FSB was from a Tantal. $20 shipped from APEX. no pins came with it, sight barrel and post were there though.
