The best I've found so far, for a PCP, Is the A&M Marksman.

I too have an A&M Marksman on my .25 Fac Rapid and it works a treat.

Always used a Sak on my Air Arms S410 Extra Fac and it was very good.

So have I, but a bog standard HW .22 mod was actually quieter when I used one.

OP, there's very little in it, different mods can work slightly better or worse on different rifles, I think your AA400 will need an adaptor whatever you choose, I'd always start with the HW regardless of rifle.
