Great, solid, clear scope. - Bushnell AR Optics 1-4x24mm 30mm Tube Second Focal Plane Rifle Scope

I put this on my S&W mp15 and I am very impressed with the eye relief, solid construction, and lens clarity. It is a heavier scope but well worth the couple extra ounces. Make sure you use a good scope mount. There are a lot of scopes with lots of cool features like lighted recticle etc. But I will take a solid no frills scope over that any day.
