  1. Magpul Announces Their New MBUS 3 Iron Sights: “Constructed of our impact-resistant polymer”

    Not to be pedantic, but shouldn’t that lead read “MBUS 3 Plastic Sights”?

    • The term “iron sights” refers to any open, non-optical rifle (or pistol) sights. It is not a direct reference to the material the sights are made of. Who uses iron in a firearm these days, anyway?

  2. Made of polymer, and I’ll still see a bunch of pictures of guys bragging they bought them to put on those railed gas blocks. 😂

      • Call me retarded, but I wont purchase or use anything Troy because of the fact they hired the HRT killer. Not a fan of government baiting someone to do something then to kill their spouse, dog, anyone-just because a short barreled shotgun is the tool of the devil. Rant off. Troy does have cool stuff, just not for me.

  3. A lot of the metal sights are aluminum, so they are not “Iron Sights” either. I will check these out in person and may buy them if they seem functional and sturdy. I have a lot of Magpul stuff and have not been disappointed yet.

    • Agreed, Magpul has been reliable in my experience. I have taken their original MBUS on combat deployments, training and competitions, never had an issue with any of them.

      I will give these a try as well.

  4. These sights are No Good, all I can see is a thumb, oh that’s my thumb. “Tacticool hold yah got there.”
    Yeah , it’s minute of thumb.

    • I’ze prefer yer Marsupial Milradians. Yer Minute of Thumb provided larger groups. May have confused anatomy that looked like a thumb resulting in higher reproduction rates. Maybe should have stuck with hand loading. Anywho, the Marsupial Milradians work better with my front focal plane behind my bifocal spectacles.

  5. I fail to see the issue here. Backup sights in case your optic goes down. Seems like a nice way to get some sub $100 sights that are light and relatively strong. Don’t do upside down rifle pushups with them open. Problem solved.
