Weapon acquired June, 2005. It was bought seccond hand from Blitzkrieg6. It's accuracy seems to be above stock VSR levels and it's power and ROF is still within reasonable limits for CQB play (under 350 FPS) and full auto supressive fire. Groupings seem adequate for semi-auto airsoft sniping. It gets about 1.5' groupings (minus strays) and for comparison, a stock TM P90 at the same distance got about 4' groupings (minus strays).
