About the Delta Stryker HD 4.5-30x56

Delta Optical's Stryker HD is a MIL/MIL fully tactical scope made in Japan.

Delta Stryker HD 4.5-30x56 is well-made and exquisitely constructed, and you can tell it's a high-quality item. It weighs approximately one kilogram, and the battery that powers the illumination is the normal CR 2032. The riflescope has a side focus parallax, which goes all the way down to 23 meters, and up to infinity.

Stryker HD parallax was previously its weakest feature, but it has been improved on this model. Parallax with an extremely long travel allows you to fine-tune the precise settings at any distance.

The reticle subtensions are always in MIL, meaning they matched the click value of the turrets. The click is always one centimeter. There are three different variations of the reticle available with Stryker HD 4.5-30x56 scope: LRD-1T (Christmas tree type of reticle), L RD-1P (tactical reticle) and DLR-1 (tactical reticle). All the reticles are illuminated.

Illumination system has 11 settings and it's meant for low light use only. This is not a wide-angle CQB scope, it's a long-range riflescope. The only thing that is lighted with the DLR-1 reticle is the center dot, which is ideal.

Delta Optical Stryker HD 4.5-30×56 scope has improved turrets that feature a locking mechanism and have 10 MIL of travel per one revolution, 100 clicks in one turn. The first generation's turrets lacked a locking mechanism and had no zero-stop. The zero stop is one of the features that make this scope so appealing. It's a mechanical hard stop that stops exactly at zero. The total elevation range is 30 MRAD or 30 MIL, which is a significant amount.

The Delta Stryker HD 4.5-30x56 features a 56mm objective lens, a 6.6x zoom, and decent optics for this price range, especially considering its low cost in the category of MIL/MIL tactical scopes. The field of view is 8.3 meters per 100 meters wide, which could have been better, but it's not a major problem. It also features a fast focus with a diopter range of -3 to +3, which is great.

So far so good, turrets seem to track ok, they can still be moved without resistance in cold weather, no problem on the lenses with a wet and cold environment. Illumination is a bit on the weak side, but works in dusk or overcast situations. All in all, I like it. I would also like to the test the new Stryker HD 3.5-21x44.

First look, good job Delta Optical By
I only have it for a short time, but on the first look its an amazing optic, specially for the price. Tests in the mountains will follow and time will tell. I think this one is a winner! If something changes or I tested it enough, a follow up review or comment is likely. Thanks for the excellent service from the optics-trade team. Cheers from Switzerland

good optics, bad parallax By
Scope has good image but the parallax knob should have been better.

Decent scope, poor parallax knob By
Afordable MIL/MIL scope with most of the features I need. I miss the better turn indicator but for this price, this is not really a problem. I do think that side turret for the parallax should have been made better. It has way too little of travel and it is hard to set it correctly.
