If using a KAC spacer to make a 14.5” into a 16”, you’ll also need to use a fat stack of shims, equivalent to a crush washer. You need to take up half an inch of threads, leaving only like .2” of thread engagement. A better option is to use a 14.7” or longer barrel, if an A2 is desired, and you may still have to shim it out a bit. Or maybe a thread extension, but the shortest of those add 3/4”. More 15” barrels on the market would be great for the one-stamp A2 guys, since an A2/A1 with no crush washer only adds 1.1”.
When the Rotex can tightens and squeezes the BFA notch, what is opposing on the face of the A2? If it works similarly to Griffin’s NATO adapter, then no extended A2 is going to work unless the extension is at the rear of the device.
Edit: there’s a company that specializes in Colt or clone stuff, can’t remember who, that makes an extended A2 by welding on a longer threaded portion…they might be the thing you need.
