Got my TA-31A but haven't tried it out yet. Waiting for my upper to come from Bushy for the third time!
Anyway, there were some posts here last month giving the dimensions for their mounting screw but I cannot find the thread.
Any help??

10/32 1/2" length hex head (1/8") for the carry handle mount. I used the same screw for my #19S mount too; but some here have suggested that it is too long and the 1/4" length would be more appropriate. 1/2" worked for me... YMMV.

Did you find one that was stainless steel or galvanized? I found the dimensions but the local ACE which has about everything only has them in steel and obviously I'd prefer something that is rust resistant.

I wrote Trijicon for one and got a parked hex head machine screw. You can buy them for $15 including the special washer. They used to mail out just the screws for free but I guess they stopped that. I can also find it at a local industrial supplier (Allied Bolt and Screw) in the exact same match-up; but they have a $10 minimum purchase. Try contacting some of the industrial suppliers in your area and see if they can help you or direct you to someone they supply maybe.

Thanks Bart, I'll give it a shot.

The Trijicon comes with one screw. I mounted it on a ARMS 19S. After around 100 rounds,I took the scope off the gun and notice that the ACOG was loose and moving.I think that I will order one more screw to tighten it more. I think DSA sells it for $11. Does anyone recommend using Loctite on the screws to make sure it doesn't come loose? Also, I lost the manual to my TA31A. Does anyone have an online copy or know where I can find one.

I ran my Trijicon with just the one screw mount on both the carry handle and the 19S. On the carry handle, I did need to use the allen wrench aggressively with some blue loctite to keep it from working loose in short order. As a result, I used the same blue loctite with the #19S and just the one screw and never had any issue at all with the mount moving. I did eventually add a second screw just to feel good; but the single screw mount to the #19S never once shifted on me.
