Cobracutter,
So you mean to tell me that the DPMS Mk. 12 isn't an actual Mk. 12?
I think these companies name some of these rifles after military rifles to put them into a category (DDM4, DDMk.18, DPMS SASS, etc...). Im sure DD, DPMS, etc.... don't actually mean to attempt at making a clone or convincing buyers that they are getting an actual military rifle. I could care less what people name their rifles. But, I also don't correct everyone that says clip and not magazine either. I know what they mean.
The DD MK18 is an actual MK18 except for the Auto/Burst trigger. I think DD would know, since they have one of the contracts for it. They should fucking know better than to play bullshit games with names.
