Can anybody point me in the direction of where to purchase a exact clone of the MK12 Mod 0 Spr Upper. Any info is appreciated of course.

Adco.  They're in the Industry section.

ADco has them, cmmg has an 18 inch spr option were u can get some of the Mk 12 mod o stuff like pri  gen 3  free float n such, or you could start from scratch, buy a stripped upper add a noveske,dougless or kreiger barrel and just go from there. but if u want a custom one adco or mstn would be the perfect way too go

Careful on the barrel though.  Noveske and CMMG "SPR" barrels are not machined for the OPS inc barrel collar.  They are just 18" stainless barrels, so you won't avail yourself to a Mk12 "Clone" with one of those.  Novekse can do the true SPR barrel spec, but it's a special order item.  Adco and MSTN have the right barrels, but you need to ask for that specifically.

Unfortunately, "SPR" gets thrown around a lot with barrels, but real SPR spec they are generally not.  They are usually just an 18" stainless barrel.

If you plan to use something other than OPS Inc, then this won't matter.
