Aforger?
 
Hi
Considerind doing an A forgery on a recovered drill receiver and was wondering if the front tapped hole in receiver ring is a thru hole or blind. If blind how deep is it?

Both holes are thru.

The front scope mount hole on an A4 when using the original Redfield Jr. type base is a blind hole. I'm not sure on the exact depth, but it's about a 1/4 inch deep. The rear hole is drilled through the bridge.

My notes say that the bridge is about 3/16" thick and the front hole is about 0.320" thru. At a minimum you need enough thread for your screw, and ideally you want those as long as they can be.

Yup . . . . Both forward holes go thru . . . .

In fact . . . .thatís how one can tell a fake from an original . . .

Originals will have the male thread of the barrel shank VISIBLE thru the forward-most hole in the ring . . . .something Bubba will not take the trouble to do.

He wonít remove the barrel, drill and tap, then re-install the barrel. The hole . . .after his work . . . will appear BLIND!

Not on my original 03A4 that I posted above. The forward screw is drilled into the thickest part of the rear of the front bridge, behind the recess for the upper bolt locking lug. It is definitely a blind hole as it does not extend all the way through that part of the bridge.

An 03A4 does not have two forward scope mount holes, and the hole it does have is nowhere near the barrel shank. Perhaps you are thinking about a different rifle.

then you have something lodged in the hole.
iv personally worked on, rebuilt and handled more real A4s then the average guy.
as well as built over 250 replica A4s..
on an original A4 the holes were drilled before heat treatment, all the way through.
when drilling an A4 replica. the holes are drill all the way through.
if your hole is not all the way through on a genuine A4, then likely. you have a broken screw in the hole.
