If anyone happens to have an SD billet upper handy, could you please measure the width when viewed from the front?
Imagine the brackets are the edges to measure and the circle is the bbl. hole.
Thanks to anyone who can help!
Sorry I didn't get your e-mail till yesterday, been out of the shop for a few days and things got backed up.
The dimensions are 1.5 side to side and 1.65in from the widest (corners) part of the receiver.

Thanks very much for the info!
This crazy idea just might work...
