ATN Corporation, quite well known for an outstanding collection of night vision options, now manufacturers several daytime-use riflescopes with professional specifications.
The 4-12x60LU was primarily designed as a big game hunter's device, but doubles as a highly effective varmint scope. The large 60mm diameter objective lens provides you with one of the brightest scopes made. Included interchangeable cams for the BDC (bullet drop compensator) lets you go after big game with rifles using .300 Win Mag or 7mm Magnums cartridges as well as varmint rifles with .223 or .270 calibers.
The reticle placement of the 4-12x60LU has been placed in the first imaging plane, which allows it to zoom in size along with the magnification-and quite importantly, does not allow the changes in magnification to affect the impact point.
