First Look: FX Maverick Compact 25 Cal. Overview

I have a 25 caliber Maverick with the 600mm barrel. One bit of advice I can offer you is it seems my 600mm barrel always prefers a slower speed when compared to someone shooting the more common 700mm barrel. So if you see someone shooting hybrids well at a specific speed with a 700mm barrel, I'd start at least 50-60fps lower with your 500mm barrel. My barrel shoots the hybrids well in the 925-950fps range, so I'd try starting in the 900-925fps range with your barrel. I'd suggest setting your rear reg in the 130bar area to start and you'll have to fine tune the hammer spring to get your target velocity. You really should get yourself a chronograph if you're going to be playing around tuning, it's an absolute must. I use a cheap $35 unit from Amazon that works great.
