At what range is a 20 MOA base needed?

The scope mount cants downward at 20 MOA, which will allow you to zero your gun at a greater distance. We typically recommend zeroing a rifle with a 20 MOA rail at 200 yards. Most of the time you will not be able to zero a gun with a 20 MOA rail at 100 yards. At 600 yards, a 20 MOA mount will point the scope down .

What is Moa rail?

Technically speaking, MOA stands for “Minute of Angle” – a measurement of angle equal to 1/60th of one degree. In practical terms, MOA refers to how much the scope base is tilted relative to the axis of the barrel.

What is Mrad scope?

A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right).

Can I zero at 100 yards with a 20 MOA base?

A 20MOA base is not always the best base to use, depending on the rifle and its purpose. In some cases, the scope being used when being paired with a flat shooting cartridge, cannot dial the added 20MOA of elevation out to keep the gun zeroed at 100 yards. The rifle must then be zeroed to 200 or 300 yards.

How far off the barrel should a scope be?

Our recommendation is no less than 1/8th of an inch of clearance between the bottom of the objective and the top of the barrel. Your second choice (0.160) [for scope base height] will give you enough clearance.

Can a rifle scope be mounted too high?

Senior Member. Your scope is way too high. It’s the goal to get the scope as close to the bore as possible. I’m sure you will be able to find lower rings and get proper cheek weld.

What is better Mrad or MOA?

There are a few differences between the MRAD and MOA, but at the end of the line they do not have great advantage over the other. MRAD is somewhat easier to communicate with others. If you think in yards / inches then it is easier to deal with MOA. If you measure in meters / centimetres then you better choose MRAD.
