Sight Help

Post by jmdavis on Sat Jan 31, 2015 1:40 pm

Does anyone know how to get the sight blade out of a Benelli MP95? Do I need to go at it from the left side? And, Any Idea what size tool to get to whatever is holding it. 

I have a new blade that I want to use, and thought that if I removed the adjusting screw and detent ball, I might be able to get it. No luck with that. 


Thanks, 

Mike

You got any pictures of it? Maybe I can guess =)

Edit: http://www.targettalk.org/viewtopic.php?f=4&t=26491 - a channel for the front sight, which allows the sight to slide back and forth?

It's proven impossible to get a photo. I have reached the conclusion that it is a metric Allen screw. I don't have one small enough to get at it, right now. It is small, like in the 1-1.5mm range. The limited info that I have found also says that it is locktited and may need some heat.

I think that I have read every MP90-MP95 post that contains "rear sight" on the internet in the past 9 hours. 

Thanks for the offer.

1.5mm is probably correct, since it's a European gun.

These are pretty poor quality, but would this help at all?:

I wanted to do this a number of years ago and had the same problem. I called Larry (importer) and he told me how to do it. Unfortunately I have since forgotten exactly how, but I'm pretty sure the tiny screw you mentioned is the way to go. It has IIRC a head that fits a 1.5mm hex wrench (there is a smaller metric size - 1.27mm I believe - but I don't have one, so it must have been 1.5mm). If you can get through to Larry you can get the complete instructions.

HTH,

Thanks Fred. It appears a little larger than my 1.5 mm. I will call Larry tomorrow and see what I might do differently.

I found that small metric allen head wrenches/drivers were easy to get at my hobby shop. You might have to buy a set but if your hardware store has nothing ........

The correct size is 1.5mm, but the head of the blind setscrew is now stripped. So a question for the gunsmiths/machinists. How would you try to remove it. It may or may not have locktite on it. I am not the first owner.

This most likely is a M3 usually a 2.5 mm tap drill. You can try a 2mm reverse drill (left hand flutes) McMaster Carr sells them as well as other places that sell to machine shops. Usually when drilling out the screw it gets hot and loosens up any locktite. Because the drill is going the direction of backing out the screw it usually catches it and unscrews it. Using a 2 mm drill gives you a little bit of error it you do not have it directly in the center of the set screw. The set screw might have been cracked from being tightened with out the top of the screw supported by the threaded hole or just over tightened. This should allow you to be able to clean up the hole and put a new screw in.

I'm going to pause because I am shooting on Wednesday. But I have ordered a new set screw and pin so I can cut it if I need to and mount the new rear blade. Thanks to everyone for your help. I really do appreciate it.

This evening I came home and tried a few things. What finally worked was the "wrong" bit from my Wheeler bit driver. It seems that none of the other allen wrenches went deep enough. But since the Wheeler has a bit of taper, it took the setscrew right out. The bottom of the screw was just fine (it's a deep allen head). 

So I now have a working fully adjustable windage, elevation, width and depth sight blade in the MP95. It sure seems to make it easier for my 50 year old eyes to focus on the front sight. I still need to relieve about 1/16 inch of wood on the grip, but that will wait for daylight and my woodworking files. 

Thanks again to everyone for your help.

Ready for practice tomorrow night. I had to open up the sight notch in the grip a little more that I though (probably 3/32), but now everything is good.
