Considering putting together a 6" 300 Blk Out using the KAK mini mil spec buffer tube/brace.
Going for just a very short overall set up not using a can, at least in the beginning. Would like it to run on both subs and supers.  
Considering a CHEAP 6" upper that RTB offers and build the lower. Unknown gas port size and not using a can makes me think I may have to "tune" the gas system to work, or maybe not. I'm prepared to tinker if needed.
Anyone have pics or can share experience with such a build? Even if it is using another brand barrel.

Thanks

With my limited experience, with the shorter barrels, reliability will be poor. Most likely you will need an adjustable block to get it to run.

You’re in luck, I had that exact build. BA barrel. Ran supers and subs just fine with a can.

Yeah, they just won’t collapse flush like the SLM does.
