Description

There's a lot to like about a short-barreled gas gun that doesn't overcomplicate things, and the Adler HT-104 keeps it refreshingly simple. This is a piston-operated 12 gauge semi-auto with an 18.5 inch barrel, a 4+1 capacity, and a plain bead up front. Made by Adler Arms in Konya, Turkey and brought in by Four Peaks, it covers home defense duty, tactical training, and casual range days without asking much in return.

What Makes the Adler HT-104 Tick

The receiver is machined from 7075-T6 billet aluminum, which is the stronger stuff compared to the more common 6061, so you get a light gun that still holds up to steady use. The barrel is 4140 steel with an oxidation-resistant treatment, and it's proof tested at the factory. The 3 inch chamber gives you room to run everything from standard 2-3/4 inch target loads up to full-power buckshot and slugs. Controls stay familiar: a cross-bolt safety at the trigger guard, a standard bolt release, and nothing fancy to slow you down under stress.

Shooting the HT-104 Semi-Auto

Gas piston operation does two things well here. It softens felt recoil compared to inertia guns, and it cycles consistently once the gun is settled in. Adler recommends a short break-in of about 25 rounds of stouter ammo, think buckshot, slugs, or 1-1/8 oz loads moving at least 1,300 fps, before switching to lighter target fare. After that, it feeds a wide range of shells reliably. The oversized rubber butt pad on the synthetic stock takes even more sting out of heavy loads, which matters when you're running drills all afternoon.

Where the Adler HT-104 Fits

At 18.5 inches, the barrel keeps the gun quick in tight spaces and easy to maneuver, whether that's clearing a hallway in a worst-case scenario or working a shoot house course. It's a straightforward, working-grade defensive shotgun that gives you semi-auto speed without the premium price tag attached to the big-name gas guns. Keep it clean, feed it decent ammo, and it'll be ready when you need it.

Frequently Asked Questions

Does the Adler HT-104 need a break-in period?

Yes, and it's a quick one. Adler recommends firing about 25 rounds of higher-power ammo such as buckshot, slugs, or 1-1/8 oz loads at 1,300 fps or faster before running lighter target loads. Once the gas system is broken in, it cycles a wide range of shells reliably.

Is the HT-104 gas operated or inertia driven?

The HT-104 uses a gas piston operating system. That generally means softer felt recoil than an inertia gun, which pairs nicely with the oversized rubber butt pad when you're shooting full-power 12 gauge loads. It also keeps cycling consistent across different ammo types after break-in.

What loads can the Adler HT-104 handle?

The HT-104 has a 3 inch chamber, so it accepts both 2-3/4 inch and 3 inch 12 gauge shells. That covers everything from light target loads to full-power buckshot and slugs. Just stick with the heavier stuff during the initial break-in for best reliability.

Who makes the Adler HT-104 and where is it made?

The HT-104 is produced by Adler Arms in Konya, Turkey, a region known for shotgun manufacturing, and it's imported into the US by Four Peaks Imports under the ATA Arms umbrella. The barrel is proof tested at the factory, and the receiver is machined from 7075-T6 billet aluminum.
