Nikon M-223 Riflescope -
Nikon M-223 AR Riflescopes give you proven Nikon Monarch scope quality and performance for high performance AR rifles.  Designed specifically for AR rifles firing the 55-grain polymer-tipped .223 Rem NATO round, the M-223s are packed with the latest retical and adjustment technologies from Nikon to help you put your shot on target every time.  Rapid Action Turret technology allows you to dial in your elevation anywhere from 100 to 600 yards away in less than one revolution. This adjustment is controlled by zero reset turrets with side focus parallax adjustment. The Ultra ClearCoat optical system provides the shooter with a bright, sharp, incredibly flat sight picture and up to 95% light transmission. Eye Box technology delivers a 4x zoom range with a constant 4'' of non-critical eye relief and a large ocular lens for a huge, exceptionally bright, high-resolution sight picture. The M-223 scopes use 1'', one-piece main body tubes for maximum strength and durability with minimum weight. Nitrogen-filled and O-ring seals for trustworthy waterproof, fogproof, and shockproof performance.  Color: Matte Black. Manufacturer's lifetime warranty.

Nikon M-223 scope

I bought this scope after much research. It is specifically designed for the AR-15 rifle and loads. I think it is the perfect scope. Easy to use and zero in. It is the best scope for the money that I have found and perfect for my AR-15 application. Would buy another if the occasion arises.

I own an M 223 and M 308

I really like this scope as it is clear and has a good sight picture. It holds zero over and over. I have had no complaints or problems with the M 223 or M 308

Negative Reviews:

Great optics, but not for an AR or for long range.

Bought the 2-8 version, and the turrets don't lock. It's very easy to accidentally pull them up and lose your zero. But the bigger problem is the "rapid action turret" range markings. They do seem to be for a 55 gr. bullet, like a Vmax, at 3240 fps. But... with a 1.5" scope mounting height. That might be reasonable for a bolt gun, but on an AR, they are pretty far off, normal height being more like 2.75". This skews the numbers-- with 55 gr. in a 16" AR, they are very far off. Nikon should have included a normally-marked cap, but they did not. A piece of masking tape and a sharpy can customize it, but that's a tacky if effective solution. On my scope, the turret is marked for 200 yards at 1.5 MOA down, 300 3.75, 400 6.5, 500 10.25, 600 14.75. The markings out to 800 yards might give one a grandiose feeling, but the cartridge they calibrated to is subsonic by 675 yards. The optics are good and clear, but the turrets' lack of a lock make this unsuitable for hard use.
