As always, Joe . . .
The new Air Venturi G4 pump arrived from Long "Guy"Land Airguns in good order. A quick snug of the fittings with a small crescent wrench and a small dab of silicone grease and it was "Pogo" time. It fills the smaller BSA Scorpion carbine quite easily. Haven't pumped the AA-S410 yet, but I have no doubt that it is a great back-up for my scuba tanks and that it will be a good option when I am hunting this fall and don't want to have to lug the scuba tank up to the mountain place.
Thanks
