The extraction starts with the rotation of the bolt. Stuck cases are a thing of the past, easy removal and safe ejection of the case or cartridge is ensured under all conditions.

The cartridge is pushed under the extractor claw and held there during feeding. As a result, a safe and trouble-free feeding of the cartridge into the chamber is achieved in every possible weapon position.

The case is held in the ejection process by the extractor claw until it is ejected by the fixed ejector. Depending on the bolt velocity, the case drops or flies out of the action. This allows a situation-dependent ejection.

The safety has three positions: „fire”, “safe” and „safe + locked“. The safety acts directly on the striker therefor an accidental discharge as a result of a broken sear is impossible.

Robust and reliable locking through three load bearing lugs machined from special high strength steel. The resulting 60° bolt throw allows for fast and reliable operation under all conditions.

The match grade trigger can be precisely adjusted to your wishes. It has a outstanding, crisp characteristic for optimal trigger control.

All rifles of the JPR and UPG series feature a threaded muzzle.

The small opening angle of 60 ° allows fast cycling.

The stock of the UPG-1 is adjustable for LOP and comb heigth. Additionaly the complete Stock assembly can be removed and e.g. be exchanged with a folding stock.
