[ARCHIVED THREAD] - Matech BUIS questions

Posted: 7/3/2005 3:35:12 PM EDT

Hello all
I got this used (looks new) Matech BUIS and it didnt come with any instructions so i have a couple of questions.
#1 What is the line under the 300 Meter mark for ?
#2 Is it made for a std. FSB or F-marked FSB? I have a std. FSB and it zeroed in with the front sight not much higher than with a A2 upper on the same barrel. ( Or am i just lucky?)
#3 Any one have a way of copying me a copy of the instruction? I will be willing to pay postage.
Thanks for all the help E3

I may be able to help as I have one on my issue M4. If I remember right, the directions did'nt really address zeroing the sight, but installation which is pretty self explainatory. To zero we put the knob on the line below the 300 meter marking, which I beleive is 250 meters, and zeroed at 25 meters with the standard USGI M4/M16A4 zero target. The sight should be regulated for the "F" FSB on the M4 and M16A4 but you should'nt have any problem zeroing with a non "F" FSB as you noted. I may have some directions someplace but you probably dont need them, it was only 1/2 a sheet of text anyway. Its a robust sight and kept zero thruout my deployment to Iraq, although the little tab that holds the sight apature locked down tended to wear off on quite a few of ours. We fixed it by putting a rubber band around the sight to hold it down.

I woundered if that would be problem. The tab is so little for the job it has to do. I keep mine lubed and when i put the site up or down i push it away from the tab to put the least amount of presser on the tab. Thanks for the help also.

According to the directions I had, you use the "inbetween line" for the 20" and the 300 meter line for the 14.5", both at 25 yards.

Help! Help! Help!

I recently purchased a Matech BUIS and I am quite befuddled! How in the hell I do get the rear aperture to open (come up) from its locked down position? I do have the instructions that came with this item, but the instructions is just all text and tells me how to do everything except how to open and close (raise and lower) the rear aperture. Help!

Thanks

PS: I do have the instructions of anyone is interested in a copy.

Just push it up. there is a tit that sticks out all you do is push or pull the sight past it. Look at the pictrue i posted above it shows the tit. There is no lock or anything like that.

Got It! I am a part-time technical writer, and this is an excellent example of poor technical writing; how the author of the Matech BUIS Instructions just assumed knowledge on the part of his audience of how to completely use this item. The written instructions tell you how to: install, zero, and maintain this BUIS, but not the basic functionality of raising and lowering the aperture, so simple and basic that it is easy to overlook. I had tried several times to push up the aperture, but it was so stiff, at first I was afraid I was going to damage it; know I know positive force is needed.

Thanks for the help.
