Product Description

Description: Sure Cycle Magazine Extension Tube for Mossberg 930 & 935. 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.

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 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 Mossberg 930 & 935 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.

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: MOSEXT 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.

I purchased the +6 mag tube extension. Midwestern Gun Works is without a doubt one of the best places to purchase your necessary parts. Great prices, only high quality parts, and the fastest shipping I’ve ever had. I think I had my order in the mailbox in Washington St. in two days. I jokingly told a friend that I think I placed my order and their guy jumped in his car and drove straight to my house.
