I have a lightly used, fired to make sure it went "boom" Remington 870 Marine magnum.
12-gauge, 2 3/4" or 3"
Holds 6 in the tube, 4 in the SpeedFeed stock, (2 rounds on either side, see pictures) That's 10 rounds without hanging ammo from slings, etc.
SpeedFeed forearm is shorter and has deeper ridges for a better grip.
Solid steel receiver. Entire gun, inside and out nickel plated.
$590 + $25 shipping to your FFL
First picture is before I added SpeedFeed stock and forearm.
