US Army uses it for good reasons! Cav Trooper 19D does 2 awesome vids on these sights
Its a great military grade BUIS! One of the best. Its a single aperture, windage/elevation adjustable, easy to build training upon with new privates. If you want to know everything there is to know about these sights, check out Cav Trooper 19D’s YT channel. He’s a combat vet Army officer that goes into incredible detail about these sights. 2 videos actually. One covering the maintenance of the sight and the other how to setup and use it correctly. Really goes into the finer points as well as the Army doctrine behind these sights. Really makes you glad you bought a MaTech after watching. Probably the most underrated YT channel there is if you want to know real military firearm knowledge from all militaries from someone thats a current Army officer. Not even retired, hes still in the Army and doing vids. Wealth of information. I think a lot of people would benefit watching the vids on these sights to get the most out of them. I love this BUIS and work incredibly accurate. Ringing steel with ease at 400 yards and meters.Read full review

Ma Tech rear BUIS
Good enough for US military and good enough for me as a backup. Only downside is that the sight uses two spaces on the rear of your rail and requires a primary scope mount that can mount in a position that will allow proper eye relief for the optics platform used. The presence of clearly marked and easy to use distance adjustments is unique and valuable as a backup iron sight feature. The lock down is tight and the sight does not interfere with charger handle use. Finish is excellent on these used sights that are over 10 years old with no evidence of rusting. Cheaper sights do not have the fit and finish of these professional backup sights I have used other less expensive backup sights and find the quality of these sights to be far superior. The flip up is not " spring loaded", but requires a firm finger pull up into position with a lock in that is easily felt and gives confidence that the sight will not move until you physically push it back down. Highly recommended.Read full review

Real Deal
Retired 19 series here - Alpha, Kilo and Delta...
this is the real deal... i have compared it to the one i bought back at Ft. Benning in the day... they are identical...
bottom line: if you are using any other BUIS system you are wrong...
pro tip: these sights were designed to use with the stock fixed front sight on the M16A2 or M4... i know most of you have removed this fixed front sight... which is a mistake... plus you loose the bayonet mount...
many after market front sights are incompatible with the correct functioning of this rear sight... these front sights sit too high/too low or the post is too wide... magpul seems to be one of the worst offenders...
with a stock mil-spec front sight and this rear sight, shooting off a bipod 600m shots are easy... 300m are nearly guaranteed if you have any skill with a rifle...
follow proper 25m Battle Sight zeroing procedures and you'll be a rock star with this bad boy...
See y'all at the Green...Read full review

The best
Personally I think there the best. If you might or ever shoot long range at a variety targets at multiple ranges. Aka combat this sight is quick and easy. It's clearly marked and not confusing under stress. Quick to adjust different ranges and engage targets. Most people's rear sights don't have an aperture adjustment and it's very important to have that or you will hit way below your target at 300 meters.Read full review

Great BUIS!!
The Matech rear sight is a must if you are doing a Clone Build! Not only is it the correct sight to use but it's also very durable, easy to use functions great! All around great rear sight!

Genuine article and good shape overall.
This sight was cleaned up well by the seller. Being a used sight the finish on the corners was bright and there was residue of rust and oil in the hinge. Engraved code on the underside matches a Matech sight I had new from its OEM Marine Corp package. Fully functional and still in good cosmetic shape too. The parkerized finish on these are tough. The controls track well and the folding sight leaf stayed up and down as needed not showing much if any wear on the detent or notch. Would buy again without a second thought. Beats import sights and feels better than plastic. I have little need for dual aperture on a back up.Read full review

Terrific buy!
Arrived the day of expectation, brand new, not a mark on it. I have an ACOG & this is designed to flip up and through the viewfinder you see your fiber optic lit reticle on the ACOG perfectly. Would highly recommend for BUIS with ACOG!Read full review

Very Rugged BUIS
This sight is pretty awesome. Slapped it on my BCM M4. If it’s good enough for the military, it’s good enough for me. Nice being able to zero in at whatever yardage without wasting a ton of ammo, not to mention having the ability to reach out to 600 yards.Read full review

Professional Grade
Professional Grade Equipment. Easy to install and simple to operate. Well made and rugged. There's a reason the US Army uses this sight on their rifles.
