This adapter allows for mounting an AR extension tube and side folder to the Crosman 2240, 2240XL, 2300T, etc. I’ve lifted the centerline to get the adapter out of the grip zone and to make it look more like part of the airgun than any other option on the market. The unique, two-piece design ensures a snug fit as it clamps down to take up any slack between the Nylon coupler and the air tube. This ensures a snug fit regardless of variance from airgun to airgun. This kit only includes the adapter. You’ll need to buy the following parts separately if you don’t already have them:
AR Extension Tube
Castle Nut
Magpul MOE Buttstock
UTG Side Folder

If you’re going to use the side folder it is not necessary to add the castle nut. If you are going with the adjustable stock only you will need the castle nut to lock in the tube.

The LOP for each configuration is as follows:
AR15 Tube with MOE Buttstock – 12.5 to 15.5 inches
AR308 Tube with MOE Buttstock – 13.25 to 16.25 inches
UTG Side Folder, AR15 Tube, & MOE Buttstock – 14.5 to 18 inches

No instruction are included with these items. To install the adapter you will need to remove the OEM hammer spring cap (Tube Plug) and replace it with the steel adapter from Buck Rail. Once you’ve done that and snugged everything up you can attach the Nylon stock coupler to the adapter and install the screw. Now you’re ready to thread in a stock tube, side folder, etc.

Please Note: This adapter will make it so that you cannot use the OEM iron sight. This kit is also not compatible with rear cocking handles or power adjusters.
