Had this mounted on my work gun for about a year but recently was issued a new shotgin with the extension included.
Three-shot extension for Remingon 20" barrels. Includes all hardware (mag spring, barrel clamp, etc.) in the Remington factory box.
Extension has scratches in the parkerizing but no dings or dents. Rode in a horizontal gun mount in my patrol car rather than in my trunk.
$35.00 shipped to you in the cotinental US.
No PayPal please.
Will consider a trade for a set of black Cav Arms C6 handguards (the mid length M4 profile HG's)
