Top secret - sorry.

Anyway, somebody posted the numbers awhile back but I don't think the search goes that far back.

Yeah, I couldn't find anything on the search.  I have an idea of the numbers, I just wanted to see if they'd match with someone who has more experience with 'em..

I'm not really sure if the true SPR profile numbers were posted or the WOA version of the numbers were posted.  I am not sure, but I have a feeling there might be some subtle differences in the profiles.

are you sure on that?

can anyone else confirm the diameters of a bull barrel, h-bar, SPR, and life under the guards... ?



My 18" SPR contoured barrel from WOA is .850 under the handguards, .750 in front. I remember a vendor here having some earlier that were .825 under and .750 in front.

Forward of the FSB/gas block area, there has to be a step for the collar to seat on.  Not sure what the diameter is before and after, but I know that there is a step there.  I'm also not sure where exactly this step occurs on the barrel, either.
