Lancer’s carbon fiber LSX extended shotgun magazine tubes are the ultimate increased capacity solution for hunting, competition, and home defense. Designed to install in place of the factory magazine tube cap, these smooth-feeding extension tubes provide increased capacity for most popular shotgun models while adding considerably less swing weight than traditional aluminum extension tubes.
Includes an extra-long spring which can be cut to the desired length during installation. Extension tube clamps are available for tubes that extend beyond the end of the barrel.
Choosing a capacity…
Lancer LSX tubes are sold in a variety of capacity configurations, which are labeled according to how many additional shells they will hold in the tube. For example, if your shotgun currently holds 3 shells in the factory tube and you add a +5 LSX tube, you will now be able to hold 8 total shells in the tube.
NOTE: Capacity rating is based on standard 2-3/4″ shells. Measurements are OAL (Overall Length), and include the extension nut.
- Precision machined aluminum adapter nut
- Lightweight carbon-fiber tube
- Available for Benelli, Beretta, Mossberg, Remington, and Stoeger models
- Select from +2 through +9 lengths for most models
Compatibility has been confirmed with the following models. LSX tubes may fit additional models; please contact the shotgun manufacturer to determine cross-compatibility.
Benelli | Beretta | Mossberg | Remington | Stoeger |
|---|---|---|---|---|
M1 | 1301 Competition | 590/835 930/935/940 | 870 | M3000 |
+2 (5.6") | +2 (6.3") | +2 (6.5") | +2 (6.2") | +2 (5.60") |
DISCLAIMER
In some states, the same regulations that apply to capacity limits on detachable rifle and pistol magazines may also apply to shotgun magazine tubes. It is the customer’s responsibility to research the laws and regulations in their state and community prior to purchasing an extended magazine tube.

Fantastic extension for my Benelli M2. Light and strong, looks killer, easy to install, and works great.

Finally snagged a +4 for Benelli M2. (Thanks Midway.) This is the longest Lancer tube that won’t extend beyond the muzzle of a Benelli 21″ barrel. Installation is straightforward; the supplied spring has to be fitted. The LSX clamp adds 4-5oz or so, offsetting the exceptionally light weight of the tube proper. This might be a factor with inertia-driven guns, depending on whatever else is attached.. Constructively intended comment: At 10 1/2″ length, this +4 tube makes the M2 a 7-shell magazine gun. It could be an inch longer, thus accommodating five nominal-length shells before spring stackup, while still not extending beyond the muzzle of the 21″ barrel. It would still be +4 for slugs due to slightly longer unfired length of typical slug loads. (Or just plug in an extended choke tube and use the existing +5 tube… if we can find one…)

This is a great mag extension for a Benelli. adds very little weight and with the added capacity you can make snow geese fall like rain.

I got this for my Beretta 1301 Competition for 3 gun. It’s been running now for 2 years without problems and is flat out reliable and pleasing to look at. I almost hate chucking it into barrels for transitions to the other guns. Mine is a plus 5 and I do use a barrel clamp. With this setup the gun come in at 7 lbs.
