magpul pistol


Best place for all your rifle need guys are great prices are better I will keep going back

Same MBUS new color


Good backup sights. Extremely durable in the closed position. Wouldn't be my first choice if you are using them as your primary sighting system.



Great product for the price!! Co-witness well with the primary arms optic and hold zero!

Best Bang for your buck sights


I love how light these back up sights are, they feel quite solid.

Rear back up sight


Sight works exactly as stated, above all, customer service, and hospitality is top notch.

Great back-up sights and they're gray....


This is my second set of MagPul MBUS Gen 2 sights, with the first being your standard black. I needed another set for my other AR upper, but most back up iron sights cost more for just the rear sight than purchasing front and rear MBUS's so I opted for them again. My first set sighted in easily, held a great group, and are just plain rugged. I'm a big fan of gray as it blends in with so much in both urban and rural environments. It is quite versatile. This gray is dark, really a charcoal gray and not too different from black. That being said it does make for a different look and if you're going for something other than black give this a go. Gray is the new Olive Drab, versatile, utilitarian, but also cool.
