“TEC-HRO SGS” is a small, beveled rail that relieves or supports the wrist when shooting lying down/kneeling.
The name “SGS” are the initials of the Swiss national squad shooter Silvia Guignard-Schnyder”, who by building such a wedge in the belt disciplines and kneeling gave herself relief of her wrist and achieved great success with it.
The rail is mounted on the front shaft, directly behind the hand stop. As a result, the wrist bends less when shooting and ensures a much more comfortable hand position.
With less pressure pain in the wrist, the shooter can maintain concentration much better!
