I'm finishing up an 80% AR-10 lower.  My question is:  Where to spot the hole for the pin that holds the bolt catch?  If I  had to guess, I'd spot it in the middle of the bosses that it fits between, but it's a lot easier to post a potentially stupid question than to fix a hole that's drilled in the wrong place.  Anybody have a link to a dimensional schematic or blueprint?  

Many thanks.

I have a few PDF dimensional drawings, email me if interested.

Thanks Rick.   From those pics, it appears to be centered on the boss.  That seems to mike out about right too, so I'm good to go.
