Has anybody used the BAT Machine AR10 Barrel extension, or their AR15 Version? I know the reputation of BAT Machine as a precision bolt action producer, so I know they make top notch items. I purchased their AR10 Extension for use with a DPMS .260 stripped barrel that fell into my lap. Everything seems to line up perfectly when I screw it on the barrel, the feed ramps and the gas port, but I don't have a bcg yet to try and headspace. I was wondering if anyone has done this before, got a stripped barrel and used the BAT extension and how it worked out for them?
