Picked up a 12th model in .223 and love it, so now I'm considering one in .308. Current plans are for (an as yet unbuilt) 7.62x40WT and an AR-10 in one of the 6.5mm cartridges as well as having my Remington 700 .308 (5R barrel) reprofiled for the brake/collar. What kind of minimum diameter is needed to properly machine the step for the collar? The 7.62x40 WT barrel has a diameter of .740 in front of the gas block, the AR-10 barrel is as yet undertermined, and I don't have access to my 700 for measurements.
Thanks for the help.

You need a minimum barrel diameter of .920" according to my info from Ops Inc.
