lol I love these threads
Okay, never start out sniping in airsoft, believe me it's nothing close to what you think it could possibly be.
Your going to want to start off with a regular automatic electric gun, the cheapest and generally well regarded as a decent cheap starter is the kraken AK, and those are usually around 200$
You COULD play airsoft with a cheap clearsoft POS from walmart, but for 80$ you can't fix it, can't upgrade it, you have to buy a new one if it breaks, and the performance is just so far below what you'll find on the field, it's WELL worth it to spend the 200$ on the kraken.
By all means you can try using a walmart gun on a field, we're just telling you there's a very high chance your not going to have fun
