Radical FA 1:7 Carbine 12" Keymode
I caught this assembled upper on sale. Came in a very safely packaged doubled box and was well oiled in the plastic wrapper. Shipping was very quick. Mated this up with all other Mil-Spec parts lower and could not be happier about the quality of this product. Fit and finish is excellent.
Radical quality, low price!

Super slim keymod rail is slick! Dropped this on a lower I had laying around, with a set of flip up sights, it makes a beauty bare bones set-up. Very clean look, and runs just like a high dollar upper. My third Radical upper and no complaints what so ever. Again, I really like this slim rail.
