AEA Precision Airguns: What Sets Them Apart
Big-bore power
AEA's Zeus GEN 2 lists up to 1300 FPE in .72 with an 820 gr slug, and AEA calls it the most powerful mass-production air rifle in the world. The Challenger Standard Big Bore in .510 is listed at up to 650 FPE.
High-pressure rifles
The HP MAX MK2 fills to 480 bar / 7000 psi with a 150cc plenum, and AEA sells a matching high-pressure compressor.
Select fire and pump action
The SF Series switches between bolt action and semi-auto, and the Megalodon is a pump-action big bore.
Mid-bore power
The Challenger Pro (Gen 2) lists up to 135 FPE in .30 and 185 FPE in .35.
Which Brand Should You Choose?
- Benchrest and precision small bore: FX, such as the Dynamic, Crown or Impact M4.
- Do-it-all hunting in .22 to .30: either. Compare the FX Impact M4 and the AEA SF or Challenger Pro.
- Big game where legal, or maximum power: AEA Zeus, Challenger or Megalodon.
- You already own a 4500 psi compressor: avoid 7000 psi rifles unless you plan to upgrade your air source.
