One of the pioneers in off caliber AR production is Mike Milli known on hunting AR forums as Dtech.
I know he has in the past done AR-10 builds, but he specializes is AR-15 chassis builds in big and small calibers.

Mike with Olympic Arms together put together the WSSM platform. Without Mike there wouldn't be WSSM AR-15's.

Unfortunately he has a large following as well as a high demand. Expected wait times for his work are at least a year out.
http://www.dtechuppers.com/ email is the best way to get ahold of him.

I know there are only certain days he takes phone calls (one man show)... but when you get ahold of him the wealth of knowledge of off caliber AR's is amazing.

BTW... Yes, I do own a gun he built for me. He guarantees 1/2 MOA on all his builds! Mine is almost 1/4 MOA from a lead sled.
