I would like to give high praise to Trenier Outdoors out of Wisconsin. I have purchased a mountain of ammo from them along w/ three FX M3 Impacts, two Snipers, one standard (600mm). Lots of accessories, scope rings, Donny FL silencers, extra barrel liners, etc. Always a smooth transaction.
I have also had excellent service with Ken Hicks from SPAW (Southern Precsion Air Weapons) in Florida, scopes (Element), rings, mounts, etc.
In my experience one can not go wrong with either.
