Just got my Omaha 45 k to the house. The only options I seem to have for mounting is a piston and fixed barrel devise. The barrel is threaded .578x28. I can get a asr mount in 9mm in 1/2x28, can I re cut the threads to the larger dia and ream the bore to 458 so I can use the ASR feature, I have several 300 blk out I wish to shoot sun sonic with the same can on occasion. So far I am Beto impressed with the can. It would be nice not to have to pull the van apart to move it around
