Looks like you've found your mate then..
Though I would still recommend a full metal construction for years of fun. They offer more scope for mods too. A laser can be mounted on any gun as long as you can get the mount.
As far as the number of shots go, dont go by the advertised numbers. Expect about 30-60 full power shots depending on temperature and other variables.
and you said--
"The powerlets are available all over bangalore too, albeit at a premium. "
would you plz throw some light on it.
When I said they're available at a premium, I meant, expect to pay 3-4 times the actual price. Maybe more! Definitely not worth it.
by powerlets you mean CO2 powerlets, right????
Well, I was referring to the Co2 Canisters. Powerlet is the name given by Crosman to their Co2 canisters. They invented it and decided to call it powerlets. The 12gm canister is called Powerlet and the 88gm one is called AirSource.
I'm not sure where to find em in mumbai. Never been there! lol.. Send a PM to Dev. I'm sure he'd know.
About BB's, I dont know whether you get Copperheads in India. But i'm sure you can find other makes. If you can source em, try lead BBs from Gamo. They're light as the regular BBs but safer since lead ones dont recochet as much as the steel ones.
