Trijicon TA31F 4×32 ACOG with Dual Illuminated Chevron. But for the price, you really can’t beat this humble scope. This one in particular doesn’t come with a rail, so you will have to pick one up for a few extra dollars to mount it on your AR15. 4x magnification, and a wide 32mm aperture come standard on most ACOG scopes. If it doesn’t look like the typical ACOG, that’s because it doesn’t have the fiber-optic filament running along the top. No battery, like most ACOG scopes, the ballistic reticle is illuminated by a nuclear source in low lighting conditions. If you want a bare-bones ACOG, this is about as simple as it gets. Here are our picks for the best ACOG scopes for AR-15 below: 1. In this post, we’re going to go over several of our favorite ACOG scopes that we think are best for the AR-15 rifle platform. If you’re not sure about what you should consider before buying an ACOG scope for your AR, skip down to our section on that. Most ACOG scopes also have daylight reticle illumination that is facilitated by an external fiber optic or a battery. You’ll find ACOG scopes in magnifications from 1.5x to 6x. ACOG scopes are manufactured by Trijicon and have reticles that are illuminated by phosphor.

Note that ACOG adjustments come in at 1/4 inch per click at 100 meters. Incrementally adjust the scope axis until the reticle’s center matches the rifle’s impact point. The recommended method is that of using a boresighter, but the use of live ammunition at a target range should work just as well. This is accomplished by comparing the reticle’s center to the rifle’s impact point. A 1/4-inch screwdriver is recommended, but this size is not critical. Finger-tighten the knobs, then include an extra quarter-turn. Note that the studs should be aligned within the rail grooves. First, locate the knobs at the base of the clamp assembly. When ready, simply look through the scope to ensure the reticle is illuminated.ģ. The reticle is nearly impossible to see in zero-light or extremely low-light conditions until your eyes have acclimated. This should take no longer than a couple of minutes. You will want to ensure the reticle works in a dark room, but let your eyes adjust. You will need to contact the manufacturer’s (Trijicon’s) Customer Service Department to discuss the installation of a new prism assembly, but it can be done.Ģ. First of all, realize that if you don’t like the reticle pattern, it can be changed. Thus, the aiming point is lit up even in zero-light conditions.ĭuring variable light conditions, fiber optics channel an adjustable amount of ambient light into the reticle, making the ACOG a sight for virtually all lighting conditions.ġ. That’s taken care of by tritium (hydrogen-three) illumination which has a lifespan of 10 to 15 years. It’s relatively lightweight and compact and doesn’t require batteries to light up its reticle. While most hunting scopes are fragile, the ACOG is built like the proverbial tank.

But for usability under low light or stressful situations, the ACOG (Advanced Combat Optical Gunsight) possesses some awesome advantages. A lot of rifles come with a moderately usable sight that works fairly well under good lighting conditions.
