MK 85 missing screw - Need Help

[user 26080]

Can I get some help please? I bought an older MK85 in very good condition but have found a missing screw that holds the Hammer Assembly into the receiver. Can anyone tell me the thread pitch and length of plug screw needed for this? It might be difficult to carry the rifle into a store to find the correct size

Nope. he wants the set screw that goes in the left side of the receiver. Newer MKs ect use the o-ring on the assembly instead of the set screw.

That is correct GM54-120. Im sure I can find it. Just thought it would be quicker knowing the size of screw.

You might be able to just use the o-ring like newer models. Take the hammer assembly with you to the hardware store and go to the oring selection bins.

I'd get an O ring and not worry about that silly screw.
