I also own an AirForce pcp .308 and feel the same way but, I feel the same way about the AEA 357 challenger big bore side lever. Simple in design equals reliability. I have had the AEA 4 years and only replaced 1 O-ring and that might have been my fault when I put it back together from putting a bottle brush in the air tube. I hear a lot of people that have had bad luck with AEA pcp's but never the 357 big bore challengers. The .308 I have owned for 2 years and 0 problems.I can’t overstate the peace of mind that comes with owning only AirForce airguns. Every other brand I’ve owned had so many seals, I was constantly worried about leaks. My life’s too busy to deal with malfunctioning, leaky guns. Now, I don’t stare at pressure gauges or run shots over a chronograph to check if a regulator failed. No worrying about POI shift—I just shoot and don’t think twice.
