Adler A110 magazine extensions

For some shooters, the factory 5 shot version of the Adler A110 lever-action shotgun does the job. But others have found a need for a larger capacity shotgun. Particularly in primary industries, pest management, hunting or  competition such as IPSC.

We manufacture and sell magazine extension kits for the Adler. The kits can increase you capacity by an additional 2 to 6 shots, depending on the size kit you opt for.  They are designed as DIY installations and do not require permanent modifications (they are reversible).

Adler plus 2 and plus5 side by firearm watermark
The ICEng Adler +5 (10 shot) extension tube is aligned with the 28″ barrel, while the shorter +2 tube lines up with the 20″ barrel. Both kits can be fitted to either the 20″ or 28″ model shotguns.

How does it work?

We experimented with single-piece tube designs when the Adler was released, but we found the wall of the tube in single piece styles had to be thinned out too much and was at risk of splitting. We stand by our products with a full lifetime warranty, so that was not an option.

The answer was to create a two-piece magazine extension. This keeps the integrity of the extension tubes and gives greater flexibility in changing between magazine capacity sizes quickly and easily. It also gives greater control over the end length so you can tinker until its exactly in line with the end of the barrel.

Installation involves removing the factory mag tube (And putting it somewhere safe), screwing in the extension pieces and reassembling the foreend. Instructions are provided.

To change capacity, remove the clamp and swap over the extension piece for a different size one. Simple as that.

To go back to factory capacity, unscrew the whole kit and screw back in the mag extension. Voila!

Which size should I get?

Our kits can increase the capacity by an extra 2, 3, 5 or 6 shots.  The +2 extension creates a really nice weight balance, but the +5 can’t be beat if you’re looking for a few extra rounds while hunting.

The +2 style is recommended for 20″ barrel shotguns as its roughly flush with the end of the muzzle.

The +5 style is recommended for 28″ barrel shotguns as it sits roughly flush with the end of the muzzle.

These kits have been popular for hunting and local IPSC competitors looking to increase capacity while remaining under the competition’s overall gun length rule.

Lever action shotguns have been available in Australia since the late 1800s. Gunsmiths have been modifying them since this time, including class-appropriate capacity changes. Some states may have restrictions on capacity or magazine type. Please confirm with your local firearms authority to confirm your state or territory laws.
