Specifications and Performance

The Macavity Arms MA3 is available in Standard (18-inch barrel, 188cc cylinder) and Long (22-inch barrel, 265cc cylinder) configurations. The rifle fills to 3,600-3,625 PSI (250 BAR) and delivers up to 130 Joules (95 ft-lbs) of muzzle energy. Magazine capacity varies by caliber: 11 rounds in .22, 10 in .25, and 8 in .30. The LFA regulator adjusts externally from 600 to 3,200 PSI, allowing on-the-fly tuning without degassing. Weight is 7.2 lbs for the Standard and 7.6 lbs for the Long. The rifle includes a 3-year limited warranty for peace of mind.

External LFA Regulator and Tuning

The Macavity Arms MA3 stands out with its Linear Free Adjustable (LFA) regulator, accessible via a knob at the bottom of the stock. You can raise pressure by turning clockwise while watching the regulator gauge, or lower it by turning counter-clockwise and dry-firing a few shots. One owner reported consistent 860-862 FPS with 18-grain pellets once the regulator settled in. However, some users note that tuning requires balancing regulator pressure with hammer spring adjustments—excessive regulator pressure without hammer spring increases can actually decrease velocity. Despite this learning curve, owners report the MA3 “shoots great” once dialed in.

Macavity Arms MA3 Upgrades and Customization

The Macavity Arms MA3 upgrades options are extensive for a mid-range PCP. You can purchase spare parts directly from Macavity Arms, including different caliber hammer sets, valve cores, transfer ports, and trigger groups. While some owners found no velocity difference between .22 and .25 hammer sets, the ability to swap calibers and tune the platform makes the MA3 highly adaptable. The modular moderator allows you to add or remove baffle sections to tailor sound suppression and balance. M-LOK slots on the forend and a Picatinny rail accept bipods, lights, and other accessories.
