shootsoft doesnt have the best record around here anymore, and Id stay clear of clones of clones (this is apparently a clone of echo 1). I find this is an overpriced gun, id say its worth more around 300 or less. Its essentially the same as all clone l96 and bar10s. If your talking a TM vsr, thats much better. Good snipers cost considerably more, possible $1000 or more.
I wouldnt compare sniping in real life at all to airsoft. Your friend is better off trying out with an AEG first - most good AEGs can shoot the same distance or longer.
Best to try out a game first, if you or your friend are not already aware of the MAA check it out at
www.mb-airsoft.com and there is XT as well. XT has a 16 age requirement with parental permission. MAA games sometimes allow 16 as well - bringing parents along is always a good way to inch into the community.
