    ive got a complete carbine that seriously needs a new barrel and a receiver that also needs a new barrel.

    i would like to diy it. getting a barrel, wrench, block doesnt seem to be the issue its finding a damn reamer to finish the headspacing!!

    brownells has regular reamers but you gotta continually mount and dismount the barrel. while its a lot of work its not undoable. does it hurt to keep torquing it down and undoing to ream and check headspace until its right?? or should i try and find a nearly non-existant pull reamer??

    price of getting both barrels mounted is the same as buying the tools and diy. i prefer diy its more fun and expands my knowledge base of firearms

    You do not have to completely torque the barrel while checking headspace when you are finish reaming your chamber. I have re-barreled too many M1 Carbines through the years to count. Use a finish reamer and go easy. If you go too far, you will have to set the barrel back and start again. If you have any questions, shoot be a PM.
