Function of a complete extractor

The extractor is responsible for removing the case from the chamber after firing. The spring, insert, and O-ring maintain a constant pressure adapted to the specific geometry of 7.62x39 cases. On DB15s, an improperly adapted extractor configuration can lead to incomplete extractions or even case ruptures.

Adaptation to 7.62x39 caliber

Unlike .223 extractors, this model features a widened and reinforced claw profile , specifically designed for the taper of 7.62 cases. It is also reinforced to withstand corrosion associated with varnished steel or military surplus ammunition.

Materials and durability

The extractor is machined from high-strength steel , heat-treated to maintain its elasticity and hardness despite fouling or high temperatures. The spring is coupled with a rigid insert and a high-density O-ring, ensuring firm retention even with low-pressure ammunition.

Maintenance and replacement

Recommended every 5,000 to 7,000 shots, this kit allows for rapid reconditioning of the bolt. Replacement is simple: remove the pin, insert the complete extractor, and replace the pin.
