Stripped Rock River AR-15 Lowers

Have any 9mm frames

None in stock and no estimated delivery dates from RRA. My best guess is they are months from shipping more... everything they have is going to fill their complete rifle backorders. They are many months behind on that stuff.

Duh! My kingdom for a 9mm lower.. LOL just kidding with the cost of .223 ammo I should have jumped on the 9mm frame when I had a chance.

What's the difference between the two frames?? Other than the marking itself. I mean, I got a RRA 9mm upper and plan on using it with a 5.56 RRA lower.

I would say the mag well for one you wouldn't need the adaptor, there might be more but to me it would make for a cleaner frame. but that's me
