Newbie pre-purchase question

[jdausten]

I wanted your opinion on the Powerline 5693, nickle plated, bb pistol

I went to Walmart tonight and the kit (protective glasses, 350 bbs, 3 mini co2 canisters and targets) cost only $45.

I wanted to know if this is a good first gun to buy? It would ultimately become my backup weapon but for now I wanted to get someting affordable, yet not a waste of money.

My concern is if co2 guns are allowed in play at AA games and if they are good or bad to have?

Thanks in advance,
Jonathan
