The Donny FL "FX" moderator. The tanto is slightly skinnier than the diameter of the stock muzzle device. Using both in conjunction really hushes the gun to a high extent, if you don't mind the gap from the airmaks 3 chamber mod to the tanto, it'll be just fine. I'm somewhat neurotic and it ground on me. The tanto gave me great suppression at 90b running 10.3gr at 890-900 to 115b running 13.5gr slugs at the same or higher velocity. If you plan to shoot at 30 I'd personally leave the reg alone and shoot 10.34s and 10.03 slugs. The gun will be near silent.
I had a .25 tanto on a .177, which was louder than the .22's and .25's i tried the tanto on. really did a good job, so I think it's safe to assume at that velocity you'll get ideal results.
I am an AirMaks Arms dealer. I use a Yokozuna or Fat Boy II on my Krait and Katran (I'm also a DonnyFL Dealer)
Utah has the Airmaks 40 short and long moderators. Match up with and amplify the performance of the stock device.
The DonnyFL Fat Boy II is effective on the SC and compact. The DonnyFL Yokozuna has modules that can be removed, not only to reduce the size, but to further tune, the harmonics. While I am a stocking dealer for AirMaks Arms for their PCPs and most accessories, I have found the Danny FL products to be superior to any moderator that is currently available. That's based on my opinion in my experience using them every day on AirMaks Arms PCPs. Moreover, I have a 100% 60 day total satisfaction guarantee on any of my products except consumables.
By the way, currently there are only 4 authorized dealers for AirMaks Arms products in the USA. I am one of them stocking the full line of their PCPs.
