These mounts are available in 0 or 20 MOA. 

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

When zeroing your rifle with a 20 MOA mount, we recommend zeroing at 200 yards.

Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. 

The channel in the center reduces the overall mass of the mount, weighing in at 2-3oz on average. 

Also, in many cases, it will not obstruct usage of factory iron sights. 

EGW's one piece scope mounts are the obvious choice for hunters and tactical shooters alike. 

Add EGW's Practical or HD Scope Rings to make it a complete overhaul! 

Available in matte black. Custom silver anodizing is available upon request, at an additional charge of $15 (there is also a 3 month lead time associated with silver anodizing. Please give us a call if you'd like to place a custom order). 

This mount is a Picatinny-style base and compatible with Picatinny or Weaver scope rings. 

Installation: EGW recommends 20 inch lbs of torque and a drip of blue loctite (loctite is available through our website and is sold separately).

Warning: This product may be alloyed with trace amounts of lead and other elements which are known to the State of California to cause reproductive harm and cancer. To prevent exposure, do not alter the product by welding, grinding, etc. For more information, go to

perfect fit and it works
I needed a picatinny rail base for a pre 64 M70 long action 375 H&H made in 1955 in order to provide correct ring placement and eye relief. This base fits the factory screw pattern perfectly. There is no other choice that provides anywhere near as much flexibility for choice of rings or ring placement, that is also strong enough, that I can find, for this action. Before I found out about EGW, I had tried a base marketed on ebay, made in China, designated for this action, that does not fit the screw pattern for this or any known M70. The leupold q.r. system has a base that fits, its plenty strong enough, but doesn't provide enough eye relief for most modern scopes, and one is stuck with one option for rings and ring placement. I contacted EGW, and the president of the company responded, directing me to this scope base. Great company and product if you ask me.
