IIRC....the round was loaded at 2.41". It looks as if there is too much space, but that's not the case. There is a slight bevel inside the mag box that can't been seen in the picture. I know there is a minimum of 2.5" of usable mag space. I'll get a max measurement later today...


Just got a 16"-barreled Ruger American Ranch today. Jammed a long-loaded A-Max into the lands and it came out with COL of 2.525". Wonder if the Ranch has more freebore since it's chambered in "5.56"?? Should be perfect with the mag extension.

Member darrenk75b was kind enough to give up his extensions since he doesn't have a RAR yet. They should be in the mail now and I have a VX2 3-9x40 with CDS in the mail headed here also.

Can't wait to wring it out with the suppressor.
