I'm putting together an A1 using a Rock River Lower. The problem I have is the lower detent retaining spring doesn't fit in the hole. The blueprints show the hole to be .094" but my spring is .099". Is this a common situation or do I just have an out of spec spring?hinking.gif

Alternatively, you may have an out of spec receiver. Ream the hole to 0.100 inches with a drill bit. Charles.

Its possible it could be flashing, but its also possible you aren't using the correct spring.

I would certainly look for a second set of eyes, and/ or another spring before I began to drill anything out.

I say chase the detent hole with a bit to knock out the glass bead that is taking up the needed space.

I agree, just make sure you use the bit in your hand, and not in a drill. Handpressure should be more than enough to check the space, or clear something out.

Looks like the culprit was an out of spec spring. I got another one and it dropped right in.

They must have sent me the wrong spring. I bought a fully assembled lower minus buttstock. I only had to install two springs.
