Flip-Up Front Sight. MagPul did it again. Quick turn around as far as shipping.
Great back up sight
by M Regan
For the money you can't go wrong. Too bad they don't offer a tritium version.
by Steven Tabbah
Front sight went on easily and line-up perfectly through my Red Dot sight. All-in-all this product functions as advertised.
by Josh Gonzalez
Good as always these sights really suprise me for the cost they are unmatched . If you have multiple guns then u know it gets expensive putting troys on all of them this is a great lower cost alternative.
by Rodney Todd
Good sight but primary sent me 2 rear sights, instead of 1 rear and one front like I ordered. Called them and they sent me a front sight in the wrong color that I ordered, I plan on painting my gun anyway so didn't bother calling them again, but it would be nice if my sight was already colored.
Good sights for the coast, would of spend more on the Pro/ or Troy sights if willing to spend 100 on one sight.

Another quality Magpul product
by GEORGE GARVIN
I already had the rear flip up sight. This was to replace the fixed front sight on my Spike's Tactical AR so the sight picture on my EOTech red dot would be unobstructed. As with all Magpul products I own, it is great quality, appears durable, and works as intended. It co-witnesses with my red dot just fine and pops up with a firm finger press. I continue to purchase Magpul products because they work, and they are made in the USA by Americans.

I can't say enough about the MBUS. They are smooth operating, and durable as your favorite pair of underwear. The releases are very easy and intuitive to operate, but designed to prevent you from accidentally tripping them. All in all, amazing product. Magpul never disappoints.
by Elias Martinez
I have grown very find of Magpuls products after using them on several of my weapons because of the ease of use and durability. I am highly impressed with the quality of customer service at Primary Arms and plan to shop with them again. They have excellent communications and have one of the fastest shippin/receiving times I have seen. Their communication with me when I sent them an email about a product was phenomenal. I highly recommend them!!
Pop up site
by steve lewis
I love these sites! Pop up pop down, they hold zero on my ar. When down I have no problem with mounting a scope. I've had them on my 1st ar for a few years and still working great.
And this one makes 6
I now have 6 AR builds equipped with MBUS sights. They are likely the best folding lightweight AR sight for the money. They look good, work well and are much more durable than one would guess. Highly recommend.
If you plan to use these in conjunction with an optic don't think twice, they are g2g. As a primary sight they are probably fine but Id personally stick to metal.
Great back up sights
by Kelly Stewart
It's Magpul....what else can you say. I love the flip up feature and these are great back up sights for the money. They stay down out of the way until you need them, and then, instantly flip up for when you do need them.
by Matthew Farrington
Light weight and works like a sight should.

by David Phillips
