Please forgive the very silly question, but how exactly do you tell the differnce between the two models listed in subj line?

I saw a gun, advertised as Mil-Spec today, but it had the grips with the "US" on them. I just want to make sure I know how to spot the differences when going to look (at this one or any other).

Thanks in advance,

Easy and quickest way is to look at the barrel. If it is black, it is a GI, if it is Silver, it is a Mil-Spec. The GI has the lanyard loop and GI sights, the Mil-Spec has three dot sights. The ejection port is also different. The GI is standard, and the Mil-Spec is lowered.

Nice, thanks for that. Shouldn't be too bad.

GI serrations are straight, mil-spec are slanted.

.......Not to mention your wallet will be $50-$70 lighter if you buy the Mil-Spec. Either one is a very good buy. If your looking for a good base gun to build on, the Mil-Spec may be the better deal. You cannot go wrong with either, though.

The quickest and easiet way to tell is the slanted serrations on the Mil-Spec.
