Hello, everyone. I have decided I would rather have the standard A2 aperture on my ARMS #40 instead of that weird horizon line thingy. Looking at the sight, it looks like I could just buy a standard A2 aperture for about 6 bucks and disassemble the sight the same as any A2 sight system to put the A2 aperture on it. Will it work? The apertures look to be machined to the same specs. Thanks in advance for input.

Just did it last week.1/16" Punch and a screwdriver and about 10 mins on the workbench and it's Good to Go. I got tired of that goofy, horizon line, half ass, works like poo,can't get a good sight picture,what were they thinking, god awful design, aperture

Thanks, guys. I'll have to pick up a regular aperture and "git er dun". I am with you Harv24, I dont know what they were thinking with that whole horizon line thing.

What the were thinking is "ACOG clearance." I've got a TA01 in an ARMS #10, and the ARMS 40 with the regular aperature will not clear the bottom of the scope. With that little cut across the aperature, it clears the scope just barely. So if you are mounting an ARMS 40 under an ACOG, then you need that cut. At least, I needed it for my setup......

Thanks for the observation Scollins. I am planning on mounting a TA01 ACOG on a LaRue quick release lever mount. I hope the A2 aperture will work with that?

If you have a less aggressive stance you will need to mount the TAO1 all the way beck. In which case you probably will need the cut in the small apperature of the #40.



That would work. I'm not all that aggressive when it comes to "stock crawling" so I've got the ACOG mounted as far back as possible.

As for the Larue mount, I'm not sure. It may mount the scope slightly higher the ARMS #10. But, you already have the cut aperature, and it sounds like it is cheap and easy to swap them out. You could do the swap, and if it doesn't work with the normal aperature, you can switch back to the cut one....

Thanks for the feedback, guys. I guess I will have to try that when I get my LaRue mount and see what happens. If it doesnt work, I'll have no choice but switch it back. Thanks again.
