Very cool stuff, better then some of my crap I filter out of my ass half the time.
The AWP is a version for use by law enforcement as opposed to military. Accuracy International AWP, with AWP standing for Arctic Warfare Police. The most notable feature is that the distinctive frame is black colored, not a light green colour. It also has a shorter 24" (609 mm) barrel in comparison to other models. It normally uses 7.62 mm NATO ammunition, depending on what source, though there may be other types of ammunition (such as 7 mm Remington Magnum, .308 Winchester, or .338 Lapua) it could be chambered for. The AWP should not be confused with Accuracy International AW AE which also has a black finish, but is a much cheaper non-military version of the AW series.
