best Iron Sight ever!
I was out of options after adding Leupold Optics to my M4, then a friend on a local City Swat team recommended these offset ar sights. Made of steel instead of plastic, they easily bolted on (front and back sold separately) and aligned perfectly with a laser sighting device without any adjustments. I was impressed by how comfortable these sights are to use - simply tilt the rifle 45 degrees to the left and you're ready to aim. They also fold neatly along the side of the weapon. I'll definitely be buying another set.
mbus 45 degree sights
I have been looking at these for some time. I initially bought a budget set, Chinese origin, to see if this old dog could adapt to this "new" concept of offsets. To my amazement, I changed rapidly and was quite pleased. Unfortunately, I stripped the mounting screw on the front sight almost immediately. In all fairness, it could have been my fault, over tightening, not sure. Then my buddy bought a set of these Magpuls, and I HAD to get a set. They are a pretty piece of design/engineering, slim and reliable with the excellent profile. I also like the positive lock feel when deploying. Very pleased with purchase.
Magpul offset sights
This, as with all Magpul products, is a must-have item for your SPR build. Attached amazingly tight, no wiggle holds zero very well. Great product. It comes in lovely packaging, almost too attractive to take out of.. almost! Adjusting the sight is simple and does not require any tools to adjust zero.
ar-15 offset sights
As usual, Magpul makes a great product. I am running this on my 16 inch DD that has a 1-6 scope on it. I wanted back up sights that I can use without having to remove the optic. This solves the problem. They are very accurate and easy to use.
Best BUIS Magpul mbus pro offset Sight
The Magpul offset sights are superb, especially when you have a scope mounted topside, but still, want "iron sights." They're Magpul, so you know the quality is there. They arrived as promised and at a lower price. However, delivery was the slowest. Even after prodding the seller several times, it took over three weeks to receive sights.
Magpul MBUS 45 degree sights
These offset Magpul MBUS sights are top-notch. Very low profile and doesn't take away the clean lines my AR has. Very strong and excellent quality... 3rd pair of Magpul pros, 2nd set of offset sights.
Magpul AR-15 offset sights
The Magpul mbus pro offset sights cannot compare to A.R.M.S. 40L. Width of Front and Rear Sights are too narrow. It does work as back up sights but not for precision work. It mounts out of the way and unobtrusive....so works well for what it was intended. Magpul BUIS are overpriced for plastic sights. But these are solid metal.
Magpul MBUS pro offset
Pricey, but very well made and designed, they lay very flat on the rifle and very compact. I'm very pleased with them. Magpul makes good quality add ons for the AR rifle, and these are top off the line.
Magpul offset sights
Excellent 45-degree option. Snag-free when down and are long enough to use when extended feasibly. Excellent sights.
The Best BUIS
Magpul MBUS Pro Offset Sight offers the Lowest profile of any BUIS I have seen when in the down position. These AR sights have a Solid construction. No extra metal or plastic-like most others. These sights are very efficient and effective. However I wish the finish was matte, but that's a small issue. I like that it takes up very little rail space.
Solid as expected
This Magpul MBUS Pro Offset Sight has exquisite craftsmanship, including the finish. Very low profile when folded, quickly acquired when deployed. Adjustments are a little stiff, but can be done with fingers only and I am perter sure that no amount of abuse will knock them off zero.
