Questions & Answers
Will this fit a GF3T 12 gauge pump action? Expert Answer

Sure Cycle does not list any of their magazine extension tubes as being compatible with GForce Arms shotguns. I would recommend reaching out to the manufacturer for more information.

Wiil this fit a Stoger P350? Expert Answer

The Sure Cycle Stoeger Shotgun Magazine Extension Tubes might fit a Stoeger P350. However, since the manufacturer doesn't listed that model as being compatible I recommend contacting the manufacturer to confirm compatibility.

Helpful Positive Review Works great by Dolls, June 30, 2020
I have the realtree max 5 5 round magazine extension tube and this works great. I only use 2 3/4 in shells and have had no issues at all with the cycling. I was turned off at first by another reviewer stating it doesn't work with 2 3/4 in shells bu...

Helpful Positive Review Works like a charm... by dustydog, September 11, 2020
Easy install & full-complement (8+1) flawless functioning. Just make sure to secure the *unloaded* shotgun so that the spring can't push it away from you when installing, and note that the nut for the barrel clamp is practically captive when install...

Helpful Positive Review Works great by Colt Wood, April 19, 2020
Built very well, very easy to install. Works well with Magnum loads but not 2 3/4 dove/skeet loads (they do not have enough power to cycle an inertia driven gun with the added weight of an extended tube magazine)

I got this extension for conservation snow goose hunting. I went with the plus 4 over the 5 or 6 because it was a little cheaper, but mainly because it was lighter than both. It added plenty of shots, attached very easy, and looked great with the max...

Most Recent Reviews Works and Fits Great by Jason, Verified Owner, May 21, 2020
Install takes about 10 minutes and is straight forward. Check the edges of your factory tube for burrs and rough edges and sand/file as needed before installing so it has a nice clean smooth path for all shells past the tube. This was the factory tub...

Product Info for Sure Cycle Stoeger Shotgun Magazine Extension Tubes

Magazine Extension Tube for Stoeger Shotguns. Featuring a 316L Stainless Steel Tube, a low drag red anodized follower, stainless steel spring and steel barrel clamp with sling swivel, The Sure Cycle magazine tube extensions are the premier extension for your shotgun. Utilizing a ratchet alloy collar, the Sure Cycle system allows for a very quick change by adding round capacity to the existing magazine tube. This allows the user to convert from normal capacity to higher capacity without alteration of the firearm or OEM tube.image

Great for waterfowlers chasing snow geese, 3 gunners and home defense applications. The stainless one-piece construction of the tube is coated in Black Cerakote making it virtually impervious to any rust or corrosion caused by some of the worst weather conditions.

This magazine tube extension will fit Stoeger M3000, M3500, P3000 and P3500 shotguns. Sure Cycle magazine extension tubes normally will not exceed the muzzle of most shotguns with 28" or longer barrels.

All of the Sure Cycle mag tube extensions connect to the existing factory magazine tube, therefore adding the round amount listed to the amount your firearm currently holds with the existing magazine tube.

(Example) If your shotgun currently holds three rounds in the magazine tube and one in the chamber, then adding a 6 shot tube will bring the total to ten rounds. If the shotgun holds two rounds in the magazine tube and one round in the chamber, adding a three shot tube will then increase the capacity to six rounds.
