Standard Vs. HD

Standard Scope Mount

Standard Scope Mounts

Our standard scope mounts are perfect for a lightweight mounting option that ties the receiver together for more rigidity over two piece bases. The cross slots have a valley down the center to save on weight, but are not optimal for mounting quick disconnect rings (throw lever), because most quick disconnect rings use a center recoil lug. These mounts are perfect options for almost any calibers, even up to magnums. We recommend using square cross lugs with all picatinny style rings.
Machined From: 6061 Extruded Aluminum
Anodizing: Standard
Cross Slots: Not Full Width
Quick Disconnect Ring Compatible: No
Height: Most mounts ~ .4” (measured from the top of the receiver to the top of the rail)
Price: Starts at $29.99

HD Scope Mount

HD Scope Mounts

Our HD scope mounts are our premium line of aluminum one piece bases. They are machined from a heavier duty aluminum and the full cross slots allow for the use of quick detach rings. This mount is perfect for the heavy hitting calibers such as .338 Lapua, or for the shooter who has to have the highest quality for their application. We recommend using square cross lugs with all picatinny style rings.
Machined From: 7075 T6 Aluminum (80% higher yield than 6061)
Anodizing: Hardcoat
Cross Slots: Full Width
Quick Disconnect Ring Compatible: Yes
Height: Most mounts ~ .35” (measured from the top of the receiver to the top of the rail)
Price: Starts at $49.99

What does M.O.A mean/stand for?

M.O.A. stands for Minute of Angle. For example: 20 M.O.A. or Minutes of Angle is equal to 1/3 of one degree.

We recommend:
0 MOA Base - if shooting 0-500 yards
20 MOA Base - if shooting 500-1000 yards

Is my gun a short or long action?

Actions vary, based upon brand. For a detailed breakdown of actions please see our Short or Long Action FAQ.

How high is the base I will be purchasing?

Our Tactical rails measure in at .4” - .45”. Our HD rails sit lower at .3” - . 35”.
