Started this today.. was looking at all the barrel drops next to the lathe, found a bunch of old Olympic AR15 45 ACP barrel drops when I was cutting down 16" barrels to 5" for suppressors. So far, I only have the barrel threaded for an extension, now just have to verify bolt gap and torque the extension on, ream the chamber and set headspace. I have a 5.56 bolt that I opened up to 45ACP dimensions years ago for another project that died. I also have one of the Bear Creek Arsenal bolt action uppers coming and should be here end of the week for another project. I am hoping a CMMG 45 lower will work with this upper. I am also thinking about making an integral style, reflex style or just a end of muzzle suppressor for it, then tuck it under the handguard.
