Rainmaker bolt size

[Garyfu.70]

What size allen wrench do I need for the two receiver mounting bolts on the side of the Rainmaker? None of my wrenches fit, Metric or Imperial.

Are you talking about the ones holding the upper and lower receivers together? Those I'm not 100% on size, but they're definitely Imperial - they might be 3/32?

The two that hold the rear reg block on are 9/64.

Those be the two, and there's no 9/64 in my set. That explains it.
Thanks a ton.

No problem!
