AR-Style Chassis and Adjustable Regulator

The defining feature of the Gunnar is its AR-platform compatibility. You can swap in components from the AR platform, including the textured pistol grip and the buttstock with a four-way adjustable cheekpiece . Moreover, the rifle offers multiple tuning options: an adjustable regulator, a 5-position external power adjuster, and an adjustable trigger shoe . The regulator came set at approximately 1800 PSI from the factory, with owners reporting optimal pellet performance between 1900-2100 PSI . Consequently, you can tune the rifle for different pellet weights and shooting scenarios. The sidelever action cycles smoothly, and an onboard fill gauge monitors the 500cc bottle .

Known Benjamin Gunnar Problems Owners Report

Owners report several consistent issues worth knowing. The front Picatinny rail bends under bipod weight and can impact the bottle, though this does not affect accuracy . Moreover, regulator adjustment requires draining the tank and removing the bottle, making tuning a time-consuming process . The stock receives frequent criticism for being flimsy and wobbly, with one owner noting “the stock is flimsy, wobbles” and recommending a traditional fixed stock . Accuracy can deteriorate after a few hundred rounds, with one owner reporting 4-5 inch groups at 40 yards after initial good performance . Quality control issues have appeared, including a sliding stock that was not assembled properly and a rifle that leaked air on first fill . The rifle also lacks a single-shot loading tray, making individual pellet testing difficult . Therefore, owner feedback suggests inspecting the stock and fill system upon receipt.

Accuracy, Pellet Choice, and Range Performance

Pellet choice significantly impacts the Gunnar’s accuracy. Owners report excellent results with JSB Exact King 25.39-grain pellets in .25 calibre, achieving sub-MOA groups at 25 yards . Moreover, one owner reported 1.25-inch groups at 100 yards with their Gunnar . The regulated system delivers consistent velocities when working correctly, with one reviewer reporting 890 FPS . Consequently, test multiple pellet weights to find what your individual barrel prefers. Heavier pellets in the 25-34 grain range generally perform best in .25 calibre . The Gunnar excels at small game hunting and target shooting within 50 yards, with the .25 calibre providing adequate power for varmints and pests.

FINAL VERDICT

The Benjamin Gunnar represents solid value in an AR-style regulated PCP platform. It offers a 500cc bottle, adjustable regulator, and AR-compatible components at an accessible price point . However, stock flex, regulator access difficulty, and quality control variability mean it suits shooters willing to tinker and potentially upgrade rather than expecting turnkey perfection. Purchase from a reputable European retailer with warranty support and knowledge of local regulations. Consider mounting your bipod toward the rear of the rail where it attaches to the receiver , and adding a pellet sampler pack to find compatible ammunition. Therefore, verify your country’s energy limits before ordering, as regulations vary across EU member states including Sweden, Finland, and Estonia. Shop at Airgun Armoury.
