I want to build a non SBR 629 clone with a middy barrel so there is no space between the moderator and the FSB. I think it lends a more authentic look. The faux 4.5" moderator "BRICK" makes has 1" of threading that when silver soldered to a cut down (12.5") middy barrel gives me my NFA free 16" barrel.
So will a 12.5" barrel cycle this thing? I don't want to sleeve the moderator over the barrel unless I have too.
You want "authentic?" Then don't put anything called "faux" on your rifle. Either go the NFA route, or buy a 14.5 with a pinned flash suppressor.
A middy cut down to 12.5 thankfully wouldn't work anyway.
why the attitude?
A 14.5" barrel + pinned FH sounds like a 653/655 which is pretty much a SP1.
I disagree with putting fake crap on a rifle, for any purpose. I failed to notice this was in the antiquated AR section or I would have let it go.
A 12.5 mid is less than ideal but it has been done.Quote:

Yes gas port sizing varies based on barrel length, gas system, ammunition and temperature envelope. I wouldn't use a 12.5 mid except in a 100% suppressed rifle.Quote:
