For those who do .50 cals I just thought I would post a link to a couple of pics. I manufacture the UltraMag 50 - .50 BMG mag fed upper for the AR-15.

Interesting looking piece!

How long has it been in production?

Any user feedback?

Looks like a nice way to get into the .50BMG affliction.....

Just love those different types of Ultra Mags. I'm thinking about getting one for myself!
