Stems & Adapters
We have designed and manufactured stems and adapters for every conceivable application.
Our specialists will review your system, including the gun size and muzzle break dimensions, and then make suggestions based on this information.
Exotic materials used in special stems and adapter designs include carbon fiber and sintered carbide. Our long portfolio of custom systems and extensive design experience ensures quick processing and competitive pricing.
Close Focus Mechanism
When performing the collimation (or boresighting) process, the highest degree of accuracy is obtained when targeting at as long a distance as possible (typically 1500 meters). However, in some cases, this is not possible or practical. Therefore, we offer a permanent and detachable close focus feature in the 12X and a detachable part (only) in the 8X and 10X telescopes.
