Frequently Asked Questions

What makes the Mateba MTR-6 unique in its design?

The Mateba MTR-6 is distinguished by its low bore axis, placing the barrel below the cylinder, which significantly reduces muzzle rise and felt recoil. This design also positions the cylinder above the shooter's hand for improved control.

How is the cylinder gap adjusted on a Mateba MTR-6?

The cylinder gap is set using a washer system located behind the barrel nut. The thickness of this washer determines how far the barrel protrudes, directly influencing the gap between the cylinder face and the barrel breech.

What are the challenges when disassembling the Mateba MTR-6 crane?

The crane on the Mateba MTR-6 is secured by two deep screws. Removing these can be difficult, and it may be necessary to gently bend the crane sideways after removing the rear screw to successfully extract it.

Can the trigger pull be adjusted on the Mateba MTR-6?

Yes, the Mateba MTR-6 features adjustable trigger engagement for both single and double-action modes. These adjustments are controlled by specific studs and hollow screws within the trigger group.
