I'm only familiar with high (.210") and low (.151") profile flat top dpms profile lr 308's. The one I have (Delton dt10 which I believe is now called the Echo 308, can't find mention of dt10 anywhere except a couple of videos on youtube) has a tang that measures .181".
It's definitely not armalite pattern as it has a rounded rear (nice) mating surface. I had to purchase another upper as the original that came from the factory was damaged (by me) in such a way that I wasn't comfortable using. Specifically a damn near drill through of the receiver extension due to a handguard screw with a wrecked tool hole.
What I purchased was a high profile aero upper as a replacement and as a result the bolt catch isn't doing its job. That was at a time when I thought that I would be OK using the high profile. Wrong. Gotta wait until Monday or whenever for a response.
Anyway, ignorance aside, how common is this? Is it just a proprietary thing? A wonky in between profile? I seek your wisdom.
