Can anyone take a pic of their RRA 9mm lower receiver? What I'm specifically interested in is the magwell area and how the block is held in.

Thanks.

I do believe the only difference between my 9mm and standard RRA lowers are the rollmarks... I don't have a block, I bought the 9mm b/c ADCO was out of the usual.

What I want to see is how the block is attached in the magwell of the ones that have it. The block on my Colt is held in with pins.

I'm clear, Rob. There aren't any extra holes on the RRA 9mm lowers. Nobody else is talking, but I thought the RRA block uses set screws.

The set screws are basically what I want to see. I have a Colt 9mm that looks like this, and I want to see how the RRA compares.

Some mag adapters are held in by the usual AR mag release and have a paddle release for the mag. I don't know if this is how the AR mag adapter works. I think it's an awful way of doing it.

My Hahn top load just won't fall out through the magwell. That's how it's held in. The mag release is a pass through design and uses modified UZI mags.

I wound up ordering a lower with a Hahn top load installed. The Hahn page (http://www.hahn-precision.com/armory/armory.htm) says it takes Colt & Colt-type mags.

Mine jams on every other round now. I think it's got something to do with how it's extracting- something's getting caught on the next round in the mag and the extractor is letting go leaving the casing in the upper while a round is being forced in.

I used to have a Hahn that you load from the bottom. There's a set screw that you adjust to get proper fit between the lower and the mag block.

My Stag lower now has the Colt 2 piece mag block (pinned).

Did Hahn make bottom loaders?

So it still requires removal of the upper though? Interesting...
