Gene....It's like Geico says,"so easy a caveman can do it"
1] Degas gun
2] Remove safety spring.You can see it between the trigger block halves.I used a bent dental pick to pull the end out,so you can push the safety out.
3] Remove action from stock
4]Remove screw on the back of the trigger block.
5]Remove barrel band,and muzzle brake.
6}Remove rear breech screw,take out hammer spring,and cap,as well as rear bolt cap.
5]Unscrew bolt handle,and slide the bolt all the way back to expose the tiny 0.50 breech screw.
6]Separate the breech,and barrel assembly from the gas tube.You will see a brass sleeve,that rests in the breech seal.
7]Lube breech seal,then loosen the screw that is directly in the center of the top of the breech.This will free the barrel.
8] Insert new barrel in the breech,line up the holes in the rear of the assembly,and tighten center breech screw to lock the barrel.
9]Lube new bolt o-ring,and place in on the new bolt,and reverse the above assembly process.
You only need three parts to do the conversion.....barrel,bolt,and bolt o-ring for the caliber of your choice....grand total $24.09 from Crosman.....Enjoy!
