The Predator 4 riflescope features an illuminated, second focal plane E3 reticle designed specifically for hunters! The E3 reticle is in second (rear) focal plane which allows your crosshairs to remain fully visible, regardless of magnification setting. The E3 reticle also offers 5 MPH and 10 MPH crosswind reference marks for every 100 yard increment; and provides BDC (bullet drop compensation) holdover marks for each 100 yard increment along the lower vertical cross hair. The illumination has 11 total brightness levels (5 day/6 night), and can easily be fine-tuned with a dial on the side of the scope.

Rated 5 out of 5 by from Best Glass that's Durable & Lightweight The most durable riflescope I own it's amazing it weighs so little. The glass is great and I love the E3 reticle it made my last 400 yard shot on a pronghorn in 20 mph wind a breeze.

What would be the proper ring height for a Predator4 2.5-10 42mm or 4-16 50mm on a Winchester model 70 Classic Super Grade 300 Win Mag? Thank you

I just purchased a Steiner Predator 4, 2,5-10X42mm scope for my Tikka T3 30.06 Sprg. I bought the H-Series Rings but the rings are too wide for the rail. Any suggestion on what rings I should use for this rifle set up?

Asked by: JJ73
The Tikka T3 uses a dovetail that is smaller than picatinny. You'll either need a picatinny adapter/base for the rifle, or Tikka specific rings. I'd try the base from Burris, item 410668
