Does anyone know if the the AAC brake and M4-2000 will work on a 10.3 Colt barrel with FSB? Also does anyone know if Colt 10.3s are cut downs? I think I heard somewhere that they are but I'm not sure.
I'll tell you what I'm thinking about doing, sending a 16" Colt barrel over to ADCO for them to cut down to 10.3. Do they have to do anything to the port? I think its all included, I'd have to double check but just for my knowledge does shorter barrel = bigger port or is it the other way around or are they independent of each other?
