EGW's bestselling Tactical Scope Rings are created by machining aircraft grade aluminum from billet one pair of rings at a time. They bore the holes to 30mm + 0.0014". When they machine the profiles of the rings they build in a 0.030" radius on all outside edges. Next they machine a 45 degree bevel around the entire ring and clamp. They clamp the pair on a 30mm mandrill with a 1/8" pin to keep the pair exactly together. They then thread form and tap holes in the ring. Thread forming is 40% stronger than cut threads.
The rings are serial engraved before they are separated. One ring and cap has a decimal in from of the numbers so the caps match exactly. i.e.., one ring will show "575" and its identical twin will show ".575".
We then sandblast them for a matte finish and anodize them in Eastern Pennsylvania.
The cross bolt is made from chromoly steel in our turning centers, roll threaded in house and heat treated and blued locally. The ring nut is beveled on both ends and an inset washer is used to keep the nut from scoring the finish on the clamp. The threads are roll formed for strength, fit (class 2a) and finish. The clamp is machined from billet and complete with radius and bevels, and anodized to match rings.
The rings are measured from where the ring sits on the top of the base to the center of the ring.
Rings are available in 3 heights:
If your scope has an objective greater than 56mm, the 0.990" rings or higher are recommended.
One set of rings weight in at approximately 4.8 oz.
Recommended torque of the crossbolts to 65 inch pounds and the top screws to 15 inch pounds.
1" machined Delrin Inserts are available and sold separately to accommodate a 1" scope tube.
