Description: Sure Cycle 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. Realtree Max-5® magazine tube extensions come with matching camo barrel clamps.

Great for waterfowlers chasing snow geese, 3 gunners and home defense applications. The stainless one-piece construction of the tube is coated in either Black Cerakote or a Hydro Dipped Realtree Max-5® Camouflage making them virtually impervious to any rust or corrosion caused by some of the worst weather conditions.

Available in a 2, 3, 4, 5 and 6 shot capacity, these magazine tube extensions will fit Stoeger M3000, M3500, P3000 and P3500 shotguns. These 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.

Manufacturer: Sure Cycle

FAQ:

Q.) Why a stainless steel tube and not an aluminum tube?
A.) Utilizing stainless steel allows the inside of the tube to be machined to an extremely smooth mirror-like finish. This allows both the additional rounds, follower, and spring to operate smoother, and eliminates grooves from being worn inside an aluminum tube.
Stainless tubes can be more precisely machined to ensure an exact flush contact point to the existing OEM tube, resulting in a perfect smooth finish.

Q.) Can I use my existing magazine tube follower with the Sure Cycle System?
A.) Yes. If you wish to use the OEM follower you can. However, some manufactures have switched to plastic followers for cost saving. While they can be used, we recommend the aluminum follower.

Q.) The spring that came with my Sure Cycle System is much longer than the OEM spring.
A.) The extra spring length is needed to push the heavier payload of rounds down the tube.

Q.) Can I use a Sure Cycle Mag tube extension that sticks out beyond the muzzle of the gun?
A.) Yes. This is very common among thee gunners and competition shooters using Sure Cycle Tubes. You will experience a lot of buildup of powder and residue on the top side of the tube that can be easily wiped off. Do not add any type of clamp or accessory to the tube beyond the barrel length.

Q.) I ordered a shorter tube (2, 3 shot). It does not seem I need the clamp that came with it.
A.) We include a clamp with all of the tubes. The 2 and 3 shot tubes can be used without the clamp if desired.

Q.) After shooting a while, the clamp seemed to loosen and move. Is this normal?
A.) It is recommended that you cover the area of the barrel that the clamp tightens to with a small section of electrical tape. This will give it a firm hold area and usually avoid the barrel from having any type of mark, rub or scratch.

Q.) I lost the directions for installation. Where can I find another copy?
A.) Directions for install are available here: STO12EXT Installation Instructions

Q.) Can you Cerakote a tube with a custom color?
A.) Yes. If you are looking for this option please let us know. Pricing will only be quoted per request.

Got the six shell extension sticks out slightly past the end of the barrel but cycles decently and installation was a breeze only took 5 minutes or so. Just make sure you oil it very well.

I purchased the Sure Cycle Mag Extension kit for my Stoeger P3000. Putting it together was an easy enough, (only the spring gave me fits, LOL). I made sure the barrel was properly seated, followed the directions on how to adjust the mag-tube nut, and put the barrel clamp where it worked for me. Stuffed a bunch of shells in and racked the slide...100+ rounds later, not a single hang-up. I do suggest buying a better barrel clamp...to protect finish.

Super easy install on my m3000. Only complaint I have is the clamp. The instructions indicate there’s supposed to be some kind of silicon pad or tape that protects the barrel from scratches. Definitely wasn’t included. Other than that I’m happy with the purchase. Really a 4.5/5 stars.

I purchased 2 of these same models for 2 of the same gun. 1 came in correct the other had incorrect copper. Customer service was awesome. Called customer service and they overnighted. Received on Thursday for a snow goose hunt on Monday. The dislike of the product is the cerakote has come off on both. Now the aluminum shines through. For the $300 spent on 2. They should hold up better than they did.
Awesome

This extension tube was extremely east to install. I like that it comes with the sling attachment that doubles as a secondary support for the tube to the shotgun barrel. I got the camo version and although it doesn't exactly match the camo pattern on my Stoeger it still looks really good mounted on the gun. It also feeds shells perfectly!
