How To Install Scope Mount At AR-15

Before start installation, empty the rifle, unload it, and the safety is on. The bubble level will be necessary and important at every mounting stage to make proper scope installation.

Define the comfort distance from the scope to your eye.

  • Fix the firearm tightly in the shooting rest to ensure its stability. The mount should be placed on the AR-15 rifle top and tighten its screws: first by hand then with the torque wrench, controlling the parallel and perpendicular levels by loosening or tightening the screws. Don’t over-tighten them, check the torque limit in the instructions.

FAQ

What Is A 20 MOA Scope Mount?
A 20MOA base is leaned down in the front toward the barrel. Such base canting allows more convenient adjustment of the scope altitude and gun zeroing at a larger distance (at about 200 yards) One MOA equals 1 inch at 100 yards, so 20 MOA for 200 inches at 1000 yards.
How do you use scope rings?
Rings are circular clamps to attach the scope to the firearm. The inside diameter of the rings should match the outside diameter of the scope (typically 2 in or 30 mm). The ring elevation should correspond to the outside diameter of the objective lens, the scope length, the ocular bell size, bolt lift, eye relief, and barrel contour.
Do I need to lap scope rings?
The lapping is necessary for some scope mount designs to deliver the best performance. The surface contact between the scope tube and ring can be expanded due to the lapping, which allows due alignment between the scope rings as well.
What Is an Integral Mount?
Integral mount is a transmitter, which should be threaded right onto the sensor (U.S. style one: 1/2-inch NPT, better with a pipe union fitting).
What is the proper torque for scope rings?
Ring cap screws should be tightened to 15-inch pounds with a torque driver, but no more than 18 inch-pounds. The rings may need to be lapped if there are large gaps on the sides of the rings.

Conclusion

Reliable mounting system allows the scope to help the shooter make more precise shots. It’s better to choose the scope mount with an eye relief adjustable slide. The mount should be set up duly as well to prevent the scope from slipping. There are two types of rifle scope mounts on a Picatinny rail: one-piece and ring mounts. One-piece mounts are popular for the AR-15, providing dependability in any conditions. Cantilever mounts feature a smaller footprint, convenient to position the scope for optimum eye relief on the AR-15 rifles with short top rails. You can attach built-in elevation as well to enlarge the scope adjustment range.

My love of guns is in my blood, since childhood I have spent hours enjoying the beauty of guns and adored going through their parts.

Tactical accessories are another passion of mine that I could write about endlessly - my house and garage are full of tactical gadgets, luckily my family shares my interests.

I'm infatuated with traveling that's why work at one place with a daily routine and standard schedule is not for me. I prefer copywriting and English tutoring as a freelancer. I live in a male family among constant talks about cars, guns, hunting, fishing, and, of course, dinosaurs 😊.

My husband is an obsessed hunter, and my two sons are fans of «Demolition Ranch» of YouTube blogger Matt Carriker. They are my best consultants about weapon and all-around ammunition topics. All together we share a love for adventures. Every camping or mounting hiking trip is a "small survival", giving irreplaceable experiences. Nothing can be better than the satisfaction of observing wild nature.
