As title suggests, I'm curious to know if an upper chambered in .50 BMG much like those made for the mil-spec AR-15 lower exists, only one made to mate with the most popular of the AR-10 platforms, namely the SR-25/DPMS GI/AR-308 lower receiver.

Many have suggested this to be superior to the current art of the AR-15 platform, due to the buffer tower being a probable suspect for crack formation over repeated use of the high-report .50 BMG round in an upper of its size mated to a much lighter (and smaller) lower.

Any examples out there of what I'm describing?

50bmg is too large of a round for an AR10 mag well

Noreen makes a 30-06 AR

Nobody asked if it has to go through the magwell genius

I'm referring to single-shot or side-fed uppers.





I wanted to know if one of those was made by any comp. to mate specifically with an AR-10 lower, much like those you see there mate with a mil-spec lower.

Ferret made an AR10 upper
