.270 WIN
First you need to check whats legal i think 16" is the minimum on rifles or "carbines" i have another tactical .22 and its 16" i wanted my 715T to fit into the same case. Once i added the flash hider the 18" barrel made it a little to longe to fit.
This is not an easy job if your not good with working on things and dont have the tools i wouldnt recomend it. I used a large vise mounted to a bench, hacksaw, dremel and a drill.
I used my cleaning rods and i inserted them into the muzzle with the slide closed. The rod stops at the breech face of the slide. Measures 18" so i measured down 2" and strted cutting. The cool thing about the handle version is it has a front strap mount that mounts around the barrel inside the front sight mount. I used a strip of tape and then slid the strap mount down over the tape and used it as a guide for my hacksaw. The saw chewed the strap mount up a little but nothing major the front sight hides the end anyway.
Took me a good 1/2 hour of constant cutting to get all the way threw, i kept turning it and cut about 1/16th" at a time till i got threw it. I then cleaned it up with a larger cutting disk in my dremel. All that i did on my lap with just hand tools. I then took the barrel down to the garage and mounted it in a vice between to blocks of wood. Chucked up these 1" ball grinding bits i got off e-bay in my drill and started to reshape the muzzle.
Once i got the end all the way down to the shape of the ball grider i cleaned it up with emery cloth i believe they are like 800 and 1000 then i worked down with wet dry sand paper to 2500. I got tired of hand sanding so i just put a crown on the inside with a brass tool and lappying compund i also got off e-bay. I may clean it up some more but i think this is good enough it should shoot fine like this and the flash hider covers the end so it doesnt need to be a mirror finish.
Cost me $13. for 5 1" ball grinders off ebay (pink ones)
The crown tool came with lapping compound it was also $13.
I had all the other tools, hacksaw, dremel, drill and emery cloth.
Stock muzzle shape and crown
This is the new muzzle shape and crown. Ill find out how it shoots soon.
You can kinda see the difference 2" made? *shrugs*
