I just bought an 870 with 18 in barrel and want to buy a 2 round magazine extension. Ive been looking at the wilson comat one but dont need a sling mount. Any suggestions?
I have the Remington and a Tac Star. Both work and attach just fine. The ONLY suggestion I would make is make sure it's metal. There are some plastic ones out there, and while they may function fine, I don't think they have the durability of a metal one.
Also, I'd suggest gettting one that is about .5" longer than the barrel when installed. The end of the mag tube makes a nice muzzle protector.
Oh, and don't forget to grind down the dimples in your factory tube.
I prefer the Remington extension, because I want that extra support, incase I 'bang' the barrel/extension against something.
I don't want the magazine tube, spring and rounds bouncing off the floor!
FWIW, those with TacStar extensions. . . . those tubes are great IF they work for you. They are the thinnest walled extensions on the market.
Good luck with them.
