Beeman AR2078B Target CO2 Air Rifle (.177)
In 10-meter paper target disciplines and precision indoor practice, physical control and repeatable sight pictures outweigh brute kinetic force. The Beeman AR2078B Target CO2 Air Rifle is a specialized single-shot target platform built around the legendary QB78 architecture. Engineered specifically for precision target shooting, it gives marksmen a dedicated match layout without the heavy cocking force of springers or the high setup cost of PCP fill gear.
Recoilless Dual CO2 Power Plant
Driven by two standard 12-gram CO2 cartridges loaded cap-to-cap inside the reservoir tube, the AR2078B operates with zero mechanical recoil or spring vibration. This total absence of forward/rearward surge allows shooters to maintain absolute visual follow-through (*follow-through*) directly on the bullseye during every shot.
Extended Cocking Lever & Match Trigger
Unlike standard hunting bolt actions, the AR2078B features an extended, ergonomically angled bolt lever that dramatically reduces cycling effort. Combined with a fully adjustable match trigger (pull weight, stages, and overtravel), it enables fine-tuned discharge control for hair-trigger, competition-style breaks.
Velocity and Caliber: Chambered in .177 caliber (4.5 mm), the rifle pushes flat-head match pellets (wadcutters) at approximately 650 FPS (198 m/s). This velocity window is sweet-spotted for optimal paper punching at 10 meters and short-range precision targets without causing excessive noise or air turbulence.
- Match-Grade Diopter Sight System: Outfitted with an adjustable rear competition target diopter (peep sight) paired with a globe front sight accepting interchangeable aperture inserts for maximum target alignment flexibility.
- European Beechwood Thumbhole Stock: Features an ergonomic competition-style thumbhole design with an integrated cheek rest and rubber buttpad, stabilizing shooter fatigue during extended 60-shot target strings.
- Single-Shot Tray Alignment: Direct single-shot chambering ensures match wadcutter pellets enter the barrel rifling without any deformation from multi-shot magazine indexing.
- Optics Rail Flexibility: Incorporates a standard 11mm dovetail rail along the receiver, allowing easy installation of magnified glass optics if used outside diopter competition.
While the AR2078B provides exceptional value and accuracy out of the box, target marksmen should keep two key technical factors in mind during range sessions:
- Temperature Sensitivity: As a CO2 platform, internal operating pressure is ambient-temperature dependent (~900 PSI at room temp). Maintaining consistent indoor range temperatures ensures maximum velocity uniformity across target cards.
- High Shot Count: A single pair of 12g CO2 cartridges provides approximately 60 to 80 full-power match shots, giving competitors full match capability on a single gas charge.
