• Extremely Light Weight – 73g for a 500mm (+8rd) tube
• High Strength Carbon Fibre
• Impact-Resistant Polymer

These carbon 12g shotgun magazine extensions are designed to shed weight from the place it affects you the most, resulting in faster transitions and easier gun manipulation by lowering the moving mass. Just 73g on a 500mm tube.

Note: The extension tube will add to the internal standard capacity of the gun; for instance, a Benelli M2 has an internal capacity of 4 rounds, and a +6 extension tube will give 10 rounds total in the magazine tube.

High spec carbon fibre made to our specification with a premium matte finish. The one piece carbon magazine is bonded using cutting edge adhesives used in the automotive industry for sports car chassis.

To calculate the number of rounds, count 60mm per round and +30mm for the spring and follower. For example, for a +8rd tube, you need 8 x 60mm (480mm) plus 30mm which is 510mm. Cut tolerance is +/- 2mm.

For reference, a Beretta 1301 has a standard internal capacity (without an extension tube) of 5, and the Benelli M2 (all variants) has a standard internal capacity of 4. The total capacity of the gun would be the standard internal capacity plus the extension's capacity. For example, if you would like your Beretta 1301 to have a total capacity of 10 you would need a +5 tube. All known standard internal capacities are listed below.

• Benelli M2 (all variants) - 4 rounds
• Benelli M4 - 5 or 7 rounds (depending on variant)
• Benelli Nova - 5 rounds
• Benelli Nova SPEED - 5 rounds
• Benelli Supernova - 5 rounds
• Beretta 1301/Tactical - 5 rounds
• Breda B12i - 4 rounds
• Mossberg 940 / 930 - 4 rounds
• Mossberg 590 - 6-8 rounds
• Stoeger M3000 / M3K - 5 rounds
• Remington 870 - 4 rounds

For example, if you wanted an extended shotgun magazine to take your Beretta 1301 Tactical from 5 shell capacity to an extended 7 rounds, you should select a +2 cartridge magazine tube. Magazine spring is sold separately here.

Our telescopic shotgun magazine tube has been developed over two years of continuous testing and refinement, resulting in unparalleled reliability and is significantly lighter than anything else on the market. Designed to shed weight from the place it affects you the most, resulting in faster transitions and easier gun manipulation by lowering the moving mass. Just 167g on a 380mm tube.

High-spec carbon fibre made to our specification with a premium matte finish. Our tubes are bonded using cutting-edge adhesives used in the automotive industry for sports car chassis.

The tubes are supplied with a single telescopic spring, engineered for performance with all our supplied lengths. No cutting, modifying, or trying different strengths, ready to go out of the box. Your main magazine spring, from a fixed-length tube can be reused without any modification, resulting in the same loading feel as before. 

Length-restricting internal spacer sets are available here to tune the maximum extended length, ensuring your exact shotgun configuration stays within the required 1320mm overall length. 

Main magazine spring is sold separately here.

Additional telescopic springs are available here.

Standard Length

Designed for maximum capacity with IPSC standard division where there are no maximum length restrictions or when no muzzle devices are fitted to the barrel. 

These lengths are a stock option and ready to ship with no manufacturing lead time.

For Benelli M1, M2 (all variants Field, SP, SPEED ect), and Super Black Eagle models, the collapsed length finishes flush with the muzzle on a 24" barrel with a collapsed length of 380mm (15"), extending to 644mm (25.35") for a total additional capacity of +9 rounds, 13 rounds total. 

For Beretta 1301 and A400 models, the collapsed length finishes flush with the muzzle on a 26" barrel with a collapsed length of 325mm (12.8"), extending to 527mm (20.75") for a total additional capacity of +8 rounds, 13 rounds total. 

For Benelli Nova SPEED, the collapsed length finished flush with the muzzle on a 24" barrel fitted with standard extended chokes. A collapsed length of 350mm (13.75"), extending to 591.5mm (23.3") for a total additional capacity of +9 rounds, 14 rounds total.

All capacities are based on a 60mm unfired cartridge length unless otherwise stated.

Custom Length

Want a shorter collapsed length to avoid interference with a muzzle brake, or want a larger capacity? Our custom length option ensures a tube is made to your exact specification. 

Below is our length and capacity guide, we can either make your tube to a specific length (+-2mm) or capacity. Please leave a note on your order or email us when placing your order to confirm your required specification. 

Custom lengths must be a minimum length of 290mm or a maximum length of 420mm.

NOTE: 2-3 weeks for manufacturing custom tubes. Each tube is made to order! Please read the specifications above. As these are custom tubes, we will not be able to accept returns.

NOTE: The extension tube will add to the internal standard capacity of the gun. For reference, a Beretta 1301 has a standard internal capacity (without an extension tube) of 5, and the Benelli M2 (all variants) has a standard internal capacity of 4. The total capacity of the gun would be the standard internal capacity plus the extension's capacity. For example, if you would like your Beretta 1301 to have a total capacity of 12, you would need a +7 tube. All known standard internal capacities are listed below.
