Knights armament Mk11 front sight. Kac

[geistacwm]

Hello.

Snagged this for a friend, but he decided on something else. I don't have an immediate use for it.

Sight is super clean. Spring still stiff.
One knick on the front corner.

Looking for 300 shipped. I believe its under going rate. PayPal only.

Or, trades for the following:

Genesis cnc uppers
Armalite slick side carriers/bolts
Urx4 764 13.5"
Urx4 5.56 13"
6.5c or 6mmC barrel.
Armalite or kac generally.

Thanks for looking dudes.
