I noticed @ Bravo Company that they have both 10.5" uppers and then their own BCM 11.5" uppers - is there a practical difference in that 1 inch? I guess what I'm asking is if the standard seems to be 10.5", did Bravo have some kind of reasoning behind making their shorty 11.5"?
Also, as I'm building my first AR (intended for HD), would the 10.5" be a good choice? For now I'd have to pin and weld some kind of FH on until I could talk the wife into the extra $200 to SBR it, but it seems to me that a 10.5" barrelled rifle would be pretty handy indoors... or would I get more versatility out of a 16" or 14.5" rifle?
