Title: 2400KT carbine stock
Post by: Mikeflys on March 23, 2016, 04:18:43 AM
These stocks have a habit of shifting a little around the mounting bolt. The bolts are tight but the stock can still rock a bit. I expected this having read others complaints. Has anyone found a good way of stabilizing this? I was thinking of a few good wraps of a grip tape maybe? Any other ideas that won't require a major change or cash outflow?

-007 o-rings on the pins that are on the top of grip frame on both sides. (There is a channel in the stock that slides over these pins) There are 2 pins on each side, usually can just put o-rings on the forward pins on each side. Sometimes need all 4.

Order Crosman part no. 1389A070 next time you place an order with customer support.  It's a rubber shim that fits between the bottom of the pistol grip frame and the grip handle of the stock.  It was standard on the 2250 variations but for some reason the Custom Shop doesn't include them.  Very easy to fab yourself once you see it.

On all my stocks, I made a shim.... I cut a piece of   foam pipe wrap and placed between the bottom of the frame rail and stock....took out all the wobble.....some drill and tap and use grub screws...good luck

3rd screw on the bottom. Rock solid.

I like the idea of the bottom shim. I will start looking for a suitable material.

This is the solution I employed too. I chose button heads instead of flat, but it's absolutely solid now.

I have never seen that "3rd screw" trick before. Thanks ! I usually wrap the palm and bottom section with a layer of tape and it seems to take up the slack. I am totally doing the third screw trick tomorrow.

I placed mine more toward the center of the grip base than JMJ but it will not matter. Whatever suits you.
I've done this to 5 of these guns and the seam in the base of the stock generally aligns perfectly with the grip frame centerline. I leave the frame in the stock and install the side screws. I clamp the works in a bench vise with poly jaws or something to protect it, and drill straight down through the stock into the grip frame with a #29 drill. I remove the frame from the stock afterwards and tap the frame for a 8-32. Clean the drilling and tap debris out of the grip frame so it doesn't get into the trigger or other areas. I also enlarge the hole in the stock a bit ( 5/32 drill ) for easier alignment during install and removal but it's not required.
It works amazingly well and removes ALL play in the stock at the grip frame.

Pretty much how I do mine, except I use the same screw as the grips (#6-32?, countersunk hole) and I drill a cross-hole on the other side of the rib so there's less chance of the drill or tap walking once it gets through the rib. Before drilling the hole, put some masking tape inside the grip frame - keeps chips out of the trigger - they stick right to the tape, peels right off.

I also put a screw in mine but man i wish i would have just used the shim! Less work. Always over thinking everything. Lol the screw is solid though.

My 2400kt came with the shim.  I purchased it back in November ...

I kinda like the screw idea though... Not really all that much work.

Great thread! Mine slips and always hated it. I guess that little piece of rubber was eating too many corporate profits.
