    A note on the Matech: The "line" on the elevation scale is for zeroing the 20" barrel M16A4 rifle at 25 meters. For a 14.5" carbine, use the "300" setting for zeroing at 25 meters.
    The same applies to the KAC sight.

    When setting up a combat zero on a 20" M16A2/3/4, we zeroed at 25 meters with rear sight set to 350m. This would set point blank range for 5.56mm NATO from 0 - 300 meters. With the 14.5" M4, the terminal ballistics for the same ammunition is a bit different. Zero on a 25m target is with the sight set to 300m. The 20" M16A1 sights were different and zero was done at 25m with the rear set to 300m. All of them set the effective point blank range from 0-300m. In general, until the advent of the red dot and ACOG, you set the rear peep sight to 300m and left it there as you'd be within roughly 8" vertically from the aim point from 0-300m, which was considered the effective *combat* range of the rifle -- which is not the maximum effective range. A number of studies from Korean War onward showed engagement of enemy combatants by an infantry solder with a rifle very rarely exceeded 300m. Trying to aim and hit enemy combatants while they're shooting at you and shelling you is a bit more hectic than laying prone on a range.

      @@Kosher_Slider Yup -- range targets aren't trying to kill you -- nor are they maneuvering to achieve tactical advantage -- something the range LARPers and Practical Shooting Sports dudes forget (or conveniently ignore). if you aim for center of mass in thorax and hit within 6 inches or so of it, that shot should be a severe wound, if not a "kill" for an enemy combatant not wearing a Level IV ballistic vest. Even with Level IV protection, it's going to put the hurt on with rib cage damage. That's the thing often ignored in the UA-cam ballistic vest videos. May prevent penetration, but it doesn't prevent the blunt force trauma.

      @@poolee77 Blunt force trauma? It's LETHAL well past 500 meters unless an adversary is wearing Level VI armor -- which is very heavy, quite uncomfortable and very hot in warm weather -- and yes it causes blunt force trauma. Soldiers don't wear it unless they must. Guerillas and insurgents don't have or use it. The issue beyond 500 meters is bullet drop and adjusting aim. The US Army has been repeatedly toying with alleged "future" rifles, all of which have been one failure after another. The current one being evaluated is too expensive, too complex, and heavier with fewer rounds in the basic load. I predict another failure.

    I have the Ma Tech rear sight. Mine is Army issue. I was impressed with it because it zeroed very easily at the 25 meter and qualified with it before installing my own ACOG 4X32. This was an advantage to my Joes because it can be co-witnessed with the Aimpoint M68 red dot Close Combat Optics. Before I left Iraq on my last combat tour I managed to get one out of supply before they put all their stuff into the conex for shipment back home. Fantastic sight to battle zero with and shooting steel with my Bushy M4. Now I want to find the Marine KAC. For a long time I thought the Marines were using Ma Tech BUIS on their M16A4s. Now I have to get one for those long range steel targets I want to bust caps on!! Oh yeah!!!

    Army here. nothing but Matechs in the armory. Still a little ingenious backup sight. so user intuitive with the easy range adjustments. Just wish it wasn't spring assisted and was more like the KAC. Would be perfect. No springs to wear out.
    AFAIK, the Matech and KAC are the only BUIS that can do elevation and windage. So mad props to those engineers for doing the wild math to get that elevation adjustments.

    One thing that I think is worth mentioning is that with the matech they do have a life span in that the detent that holds the sight down will wear out and the sight will stay in the up position. That was a problem with the rifles we had when I was in the service.

    Top 3 worst paint jobs I've ever seen on a rifle. It looks like you wiped you ass with your rifles, then put a satin clear coated over the shit.

    very nice site, also very good advice in reference to authentic vs. clone. list today's scam artist it took a lot out of authenticity and Trust. a simple comparison would be an authentic Indian Arrowhead verses some knucklehead manufacturing them with a Dremel kit. like I said it destroys Trust and authenticity. sincerely...

    Did you make those rifles look like shit? On purpose?? Holio fuck... I've got some old wore out shit I'll sell you... If that's your bag. 😂🤣
    Matech is the better of the two sights... Sand and dust will wreck the adjustment design of the KAC...

    What did you do to your rifle? I'ts all tan painted and looks terrible.
    Why do these guys play dressup??
    Ok....I'm going to paint my rifle green just to be difficult here. That way, I'll be a little like you guys, you know, getting 40% of what it's worth at the local gunshow, when I sell, because it's all F'd UP.
