I bought this new, and never used it.  I am now cleaning out the closet:

"The P-223 Rifle scope is the perfect addition to any AR-15 and provides perfect balance of field of view for close range engagements and crystal clear lenses with the BDC reticle for long range precision. With 98% light transmission and fully multi-coated optics, you can easily engage targets longer than the completion in low light situations. The rugged design of the P223 was built to take on any abuse that comes along and then some. One outstanding set of features is the tactical Rapid Action Turrets which allow you to make positive, quick and accurate 1/4 MOA adjustments in the field or at the range. The P223 is covered by Nikon's limited lifetime warranty."
