Thread pitch/dia for M1A scope mount

[Brobee]

Hi there....

Seems I'm missing the bolt that attaches an ARMS#18 to the side of the M1A receiver.... Does anyone know the dia and thread pitch of the bolt? Will be taking a trip to Revy shortly.....

Thanks in advance....

That bolt is non-standard. You won't be able to get anything from your hardware supply store that fits. Your best option is to contact ARMS and see if they will send you a replacement. Send them an email and see what they can do for you: http://www.armsmounts.com/

I'm not sure on the thread size, but I got one from Wolverine for about $6 a couple of months back.

It is #12-32 UNEF chances are Revy will not stock it.

Smith Ent. or Sadlak has them. They cannot be found in any hardware store. These guys get them made by a machine shop. Price is $10-$12 US! Now that's a special bolt- so don't lose it or strip it.
