thanks guys for the replies so far. To clarify, it doesnt have to be completely silent, i just want something that doesnt sound like im shooting some type of gun. It woudlnt see much backyard use, just when im tinkering with it or checking scope zero, it would mostly be for the squirrel woods.someone recommended the marauder, i have nothing against them but they are just too big and heavy for my hunting purposes. I currently hunt with a prod set up with an ar stock....so i was just looking for something similar but in 25cal with more airtank. I know i could mod my prod to 25 but by the time i was finished i could have just bought another gun so why not. I would like some type of bullpup but cant justify the money at this time, but i see used airforce guns as well as specials here and there that seem pretty reasonable for the money and the excellent ratings they get.
If I were buying another now, I would probably stick with the conventional bottle method so I could switch over to CO2 when wanted.I don't believe the spinlock arrangement can be swapped with CO2.I do like the spinlock for the gauge and fill port though.Tough decision, if I needed to make it.
what squirrel did you double tube your prod? What kind of shot count are you getting
