    Was the Romeo included in the box when you bought it?

    Just another AR? And I got a E-mail notification about this article.. Who cares!? Show me something new.

    It looks like a nice rifle to add to my collection but does it come “left handed” ?

    Nice set up for the $800 price point. The Romeo is about $175 by itself. The only thing I’d change is the trigger but I’d put in a drop in trigger in the 4lb pull range.

    Do you have a layaway plan? I love this Beauty! I don’t own any rifles…yet. Plenty of handguns.

    Cool rifle. I much prefer a gas piston system. Faxon ARAK-21 has my interest. If you enjoy fouling the chamber area with gas residues that’s cool but for me the AK style action is much more dependable.
