I'd love to use my Class III AR-10

You have a full-auto AR-10? Mine's a semi. And yes, it's also legal for hunting in VA.

Yes; 3-round burst and silencer w/ BATF Tax Stamp. I also have several AR-15s which are also Class III: full-auto, short barrels and silencers.

Lots of fun at the local ranges. I always draw a crowd, and am happy to let them try them out.

Unfortunately, there's only one nearby 1,000yd range for my Barrett M82A1 .50cal BMG to *exercise* at; anything under 1,000yds isn't worth wasting ammo.

What kind of glass do you use on it?

I'm currently using a Leupold Mark 4® 1-3x14mm CQ/T® sight, but have several other LR units to install, if I want to reach out further than 250yds.
