Product Description
Choate Machine Works Remington 20ga Light Weight Extension Kit. Two options available on this store at this time are the 2 or 3 shot and both are in a matte black finish and will match your Express 20ga perfectly. The picture is from the Choate web site as they don't show the matte finish. I'll get new pictures soon. This is the two shot and you will find the 3 shot in this same catogory.
If you have an 18.5" Barrel then get the 2 shot. If you have a 20" to 21" Barrel get the 3 shot. If the serial number on your gun starts with RS or ends in the Letter "U" then you have a light weight receiver.
The kit comes with the extension tube, spring, follower and barrel bracket with sling attachment.
