Firearm Forum Question: Review and Test Firing of the Geha Bolt Action 12 Gauge Shotgun

Ask A Firearms Question:
No question today ...
This is my personal 'Review' of the Spanish made Geha 12-Gauge Bolt Action Shotgun.
The Geha Shotgun is a strange designed bastardized conversion of an 8mm German Mauser.
Essentially they took an 8mm German Gewehr K98 Mauser, post WW1, removed the barrel, modified the magazine and part of bolt assemble converting it to a 12-Gauge Bolt Action Shotgun for hunting.
The weapon is surprisingly lightweight with a wood stock.
Recoil can be reduced by slipping on a padded butt pad.
It is a collectible firearm since approximately 40,000 were made and estimated 15,000 were sold in the USA.

Answer / Review:
Blog Administrator -
I had the opportunity to purchase two of these right here in Arizona.
They are a collectible firearm.
They have a current collectible market value range from $250.00 to $450.00, depending on condition.
I test fired my 2nd Geha 12-Gauge Shotgun at the Scottsdale Indoor Gun Range, see Target below. It shoots quite accurately with acceptable recoil using a butt pad, and is lightweight with on an old German Mauser wood stock frame.
More on the Geha 12-Gauge Shotgun can be found in the Youtube Video Below.

The clear downsides to the Shotgun are:
1) The bolt cannot be removed because the breach is larger than the opening. Most people try and remove the bolt breaking the bolt head off the extractor.
2) It is a Bolt Action Shotgun.
3) The Magazine had to be modified making it difficult for maintenance, but not impossible.
4) Limited Magazine capacity, one round.
5) Requires a 2 1/2 Inch Shell for safe shooting or have a gunsmith ream the barrel out to 2 3/4 inch. Most sold were European designed for 2 9/16 inch versus 2 3/4 inch American designed. Some were sold as 2 3/4. A good gunsmith can measure and adjust to 2 3/4 if needed.
6) The Bolt Head can come off the extractor by yanking the bolt back to far.  

The Upsides to the Geha Shotgun are:
1) Limited Production making it a collectible.
2) Value for dollar. If you acquired one of these early on the value for return is good.
3) Remarkable Accurate.

I Rate these Shotguns as a .... Novelty or Collectible, there are better choices for purchase. A NO BUY for Hunters and General overall Shooters. It is a BUY for German Collectors.

Attention Firearm and Ammunition (ammo) Manufacturers, and Makers of Firearm Accessories. I am now Testing Products and issuing reviews on the Firearms Forum (Ask A Firearms Question) site.
If you want your Product TESTED, Reviewed, and Posted here, please contact me.


  1. I would like to thank everyone who has provided Youtube Videos that enhance this Firearm Forum.

  2. I have seen one of these before.
    It was at a gunsmith when I was having my old Armi Jager Dakota Single Action revolver worked on.

  3. I see this as a method to screw up a perfect rifle.

    1. I am in total agreement.
      It maybe some kind of engineering marvel as one person indicated but who cares?

    2. A real idiot must have figured out how to screw up a well designed infantry rifle.

    3. Man do I ever so dittos on that

  4. One of the things I really like about this Firearm Forum Site is the topic posts of unusual guns and related items not found on most other sites.

  5. Owning this is of no interest to me.
    But still I enjoyed the read.

  6. I have never seen one but have heard of these.

  7. Never ever liked a bolt action shotgun. Sawed off double barrel works best.

  8. It's in Spanish made? But its a German Mauser.

    1. YES, the Spanish bought leftover German Bolt Action Mauser Rifles. Changed the barrel and the magazine and basically converted an 8mm Military Rifle to a civilian hunting shotgun.
