That should I change my 1377 to convert it to CO2? is only a proyect...
i have seen it done more lately
have at it a new tube is cheap if you dont like it!
Well, I just completed this conversion. I used a 1740 tube, striker, piercing knob, rear plug and valve. You will also need a new front sight. I used the muzzle brake assembly from a 2300S. All up cost is about $40.00. Was it worth doing? I guess so as I didn’t much like the whole pump-up routine. Also, I already had the “long†steel breech and wanted to try the “floating barrel configuration so did not use a barrel band. If you use the plastic breech you will need a barrel band.
It is just what I want, get the floating barrel ,not having to pump in every shot (I have two 1377, one mine and one for my wife, the second serious I'm going to transform.
I would just buy a 2240... maybe get am $11 .177 barrel from Crosman Customer service if you want that caliber.
Here, finally, is a picture of my conversion.
LOOKS NICE !!!!
