1 MOA increment at 200 yards is 2″. 5 of those 2″ increments fit into the 10″ of adjustment needed, so a 5 MOA adjustment is needed. 4 clicks on the scope equal 1 MOA. So, if every 4 clicks equals 1 MOA, you will need 5 of those 4 click adjustments, or 20 clicks total.

The Mil Method There are 1,000 mils per radian so, there are 6,283.2 mils in a circle. There are 21,600 MOA in a circle, so a little quick division determines there are 3.4377 MOA per mil. At 100 yards, 3.4377 MOA equals 3.599 inches (3.4377 x 1.047). Rounded up, one mil equals 3.6 inches at 100 yards.

4.0 out of 5 starsits more of a 3.5 star than a 4 star, but definitely not a 3 star. its more of a 3.5 star than a 4 star, but definitely not a 3 star. For what you pay it works well. You have to use lock-tite on the screws that hold the scope onto the mount and the screws that holds it onto the rail.

It is similar in concept to the earlier commercial Weaver rail mount used to mount telescopic sights. The Picatinny locking slot width is 0.206 in (5.23 mm). The spacing of slot centers is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm).

Top positive review 4.0 out of 5 starsGood buy! Scope is as advertised. Great accessories and features on this scope, especially for the price. The scope is variable power and very bright for viewing as well as having a great field of view out the 50mm lens.

20 mm cartridges have an outside bullet diameter and inside barrel diameter of 0.787 inches (20.0 mm). Projectiles are typically 75 to 127 mm (3–5 in) long. Cartridge cases are typically 75 to 152 mm (3–6 in) long and most are shells, with an explosive filling and detonating fuze.

The Vortex Mil Dot reticle features subtensions that are based on the radian. The terms mil and mrad refer to a milliradian—a distance that equals 1/1000 of a radian. A radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle.

VMR-1 MOA Reticle You have purchased a Vortex® riflescope equipped with the VMR-1TM reticle. Designed to maximize long distance shooting and ranging abilities, the VMR-1 MOA reticle can be used to effectively determine ranges, holdovers, windage corrections and moving target leads.

You'll want the best clarity when shooting at distance and the best clarity will be when the mechanisms are centered. If you're going to be shooting much at 500 yards or more, go with a 20 moa base.

Scope ring width refers to the diameter of the scope's tube. Most scopes have one-inch tubes and, so, this is the most common ring size. A few scopes, particularly expensive, long-range scopes, have 30mm or 34mm main tube diameters. ... Most scope rings have upper and lower or left and right halves.

Simple, rugged and not very complex would be adjectives that best describe the IOR tactical line of scopes. Pros: ... A few times I forgot to switch back to 24x power and I was amazed how crisp a target looks at 200 yards with this scope even at low magnification. Good glass does make a huge difference.

The tritium illumination has a usable life of 10–15 years. Some versions of the ACOG have an additional daytime reticle illumination via a passive external fiber optic light pipe.

The 25 mm caliber is a specific size of cannon or autocannon ammunition. It has also been recently used for the Barrett XM109 anti-material rifle. Such ammunition includes the NATO-standard 25×137mm and 25×184mm rounds, Soviet 25x218mmSR, as well as the World War II-era French-designed 25×163mm and 25×193.5mmR rounds.

Same mag capacities with both, but the 40's longer sight radius (better accuracy) and longer barrel (maximizing velocity) give it a discernable edge. Haven't mounted an MRD yet, but there's obviously that factory-supplied option with the 40 that the 20 lacks ....

Top positive review 5.0 out of 5 starsVery good setup. I have had the scope for a few months now. I am very impressed with the scope and even more after the last firmware update. I have the matching rangefinder now which makes it even better.

At night, the reticle may dim some, but the reserved power from the day provides it with sufficient power for the entire night. The ACOG is also completely waterproof, which for the amphibious Marines, is a major advantage. The ACOG can submerse to a 100 meters, which is an extreme distance for a rifle scope.
