Description

The Ataman M2 Tactical Carbine Type 4 (636/RB-SL) belongs to the M2R series of pre-charged pneumatic air rifles produced by Ataman. The rifle operates using compressed air stored in a high-pressure air reservoir, typically filled up to 300 bar (4350 psi) to provide stable velocity and consistent shot performance.

This model is chambered in 6.35 mm (.25 caliber) and uses a self-indexing rotary magazine, normally holding 8 pellets, allowing the rifle to function as a multi-shot repeater. Cycling the side-lever (SL) cocking mechanism advances the magazine and chambers the next pellet for quick follow-up shots.

The rifle features a precision rifled barrel (often Lothar Walther) designed to improve pellet stabilization and long-range accuracy. It also incorporates an adjustable two-stage trigger for improved shooting control and consistency.
