Leupold’s newest tactical scope, the Leupold Mark 4 HAMR (High Accuracy Multi-Range), is aimed squarely at a product category dominated by Trijicon¹ . The Leupold HAMR is a compact, lightweight, fixed 4x power scope designed specifically for the AR-15 and similar 5.56mm chambered rifles.

Like many of the Trijicon ACOG scopes, the HAMR is available is a red dot sight mounted on top of it. This allows the operator to quickly switch from 4x zoom of the main scope to the 0x zoom of the Leupold Deltapoint red dot when engaging in close quarters combat, where a zoom scope if undesirable. The Deltapoint is available with a 3.25 or 7 MOA red dot.

The scope uses Leupold’s CM-R² reticle, ballistically calibrated for the 5.56mm round. Leupold’s premium Xtended Twilight Lens System and DiamondCoat 2 coating ensure good light transmission. The optics should perform well at medium ranges out to 800 yards.

The below table compares the Leupold HAMR with a similar Trijicon ACOG, the TA01NSN-RMR. Neither are a clear winner in terms of features. Both cost about the same. The Trijicon with its battery-less operation and a bigger Objective Aperture lens could make it the winner if you need these features. The HAMR, on the other hand, is lighter, shorter and has much better eye relief. Ultimately the decision to purchase one or the other will come down to personal needs.
