| Anybody use these? Would you recommend or pass, would be used for co-witness Eotech. |
I've never had either, the last one I had was a Bushmaster rear flip that I bought from them directly, I sold that weapon and setup. I have a new M4 and was wonting something different thats why I'm putting the trust to you guys on ARFCOM. |

I ran that set up for a while. (EOTech/MATECH) Many installers had problems with the locking bar and bolt snapping during install. This was an “operator error” due to the installer not following the enclosed instructions, and the natural human desire to over torque fasteners. If the mounting instructions are followed to the letter, then there should be no problems. I feel the MATECH is not one of the “best built” BUIS’s out there, but if you do not have a BUIS, and can get a new MATECH for cheap, I would not pass one up. I personally had problems with the aperture pivot pin on mine wandering out during firing. This would inadvertently deploy the aperture.

 Here's a pix of my Matech mounted with an EO Tech. It does the job well, but under constant amd hard use, I do envision it's failing at some point. The actual peep stem is somewhat fragile and there a number of small parts which could fail. One of these days, I'll change it over to a same plane Troy. |

Personally, if you want a plain simple BUIS, get a 300 meter KAC and pop out the insert. I have used both the KAC and Matech and have not had an issue with either. I personally don't like the Troy, specifically the front sight, but we are not talking about them. My personal opinion is the less moving parts the better, this is why I like the KAC sight best. I do like the option of the yardage on the Matech, but being a realist, I'll never use it. Just my .02 worth. BTW: I'm currently running the Matech on my duty rifle. |

Magreload, I was hoping that FMJ might share his insight, since he implied that he had tried both the Matech and Troy which he recommended. I have zero experience with the Matech, but did put a Troy on my last build, and am very pleased with it. The application is slightly different from yours however, as I needed something low enough to fit under the ACOG and NXS. What I like about the Troy versus the ARMS #40L on my other carbine [not SP, because they weren't being made yet at the time when I built it] is that you don't need to flip any levers to deploy the sight, and even though you need to push a button to retract it, I still find it more ergonomic than the ARMS. Another thing that I like about the Troy is that it deploys with the large aperture "active" versus the small as on the ARMS #40L or #40L-SP. It is also same plane for both apertures, which to me is appopriate for a BUIS. I don't have any plans to swap out the ARMS on the older build though, as it is entirely functional, and is a BU after all. Hope this opinion helps with your selection. |

I have 3 matech's, and I love them. I like the simple clean lines, the easy snap up and snap down. I've heard people say they are fragile sights, but I've used mine numerous times in some pretty heavy duty 3 gun matches, as well as some SWAT training days, and haven't been able to break them yet. |

Magreload, The only down sides I see to the MaTech BUIS are: * Inadvertant movement of the Range Lever if it gets tangled up in your LBE * Appature is designed for distance shooting, so it is "tight and not too bright" for close up & fast shooting especially in less than optimal light conditions. Some of the other sight options offer dual appatures (similar to A-2 with small appature for distance and large open appature for low light or speed shooting. My GG&G has the dual aps. * Be sure to follow the installation instructions and do not "Go Gorilla" when tightening the lock bar. Thread locker is your friend, rather than trying to crank it so tight it won't ever come loose. For the Resonable Cost, the MaTech is a lot of bang for the bank. The range feature is accurate, but can you really shoot Irons at 600? I like the KAC 300 meter BUIS as a super simple super rugged system. I run MaTechs behind E0Tech on GG&G quick releases on my 20"s, and the KAC 300 on my M-4 clones. Your mileage may vary!  BIGGER_HAMMER  |
Main reason I dont care for the BUIS is it made MOSTLY for LONG RANGE shooting |

<<Mod Edit>> 3rd Reply  LOLI like same plane APs I like to have the same POI with both APs Troy has a Large Ap for close range Troy has a small Ap for long range Troy is well made Troy has a good following For a Carbine/M4 range in the real world is 0-300M Im a civi and wont be shooting far out any way |

The official "Big Army" BUIS is the MATECH, and if you think about it for a second, you realize that it has the same adjustments as the detachable carry handle sight does, i.e. in Army logic (let's not comment, most of us know what that entails) it is every bit as capable of an iron sight as a carry handle sight. While I don't know the exact specs it was designed to, no doubt, there was a spec sheet attached to it, and I almost guarantee, that that elevation adjustment was attached to it. That said, the only times I've seen them broken are that first five minutes of sheer terror when installing it: "did I break it?!" Once installed, however, every one I've seen has been good to go. Yes, it's true, the elevation adjustment sometimes gets knocked around. But it's part of the ease of use, that makes it a non-issue to return them to the correct position anyways. They're often used as primary sights, as well. Iron sighted flat tops are not altogether unknown, though rare. In my experience, they're pretty damned rock solid, and installed correctly, they don't go anywhere, and work for their purposes. The elevation adjustment is just something that was spec'ed out, use it or don't, it's like many other features that the military has asked for, that it didn't really need. But the sight has proven its worthiness for combat, if that's what you're asking. Otherwise, BUIS are very much like stocks, rather a matter of personal preference. It's just a hole to look through. And LaRue, Troy, LMT, GG&G and MATECH all seem to make equally useful holes. It's just a matter of what style you want. Me, I've got three MATECHs and counting, four if you include my issued weapon. ~Augee |
I think i pay the same price off e-bay too. for 40.00, this MaTech is one damn awesome BUIS...... |
Got any more info' on them? Like folding or fixed, and rail mounted or barrel mounted? |
This is the Troy BUIS  It fits nicely under virtually all optics and is a solid build I also like the Matech, mainly because it is the issue BUIS for our fighting forces - along with the Knights and LMTs (different application for the latter) (The Matech below on a pic borrowed from Buddyhoohaw  )

Folding, rail mounted. |
