What I think will be better than that is to buy a whole kit custom. Like, I want a VSR-10 upgraded to 500 fps (no way would I let someone else upgrade my rifle), have it painted to your specifications, if you want a ghillie wrap and what style of camo, what style ghillie suit (full body, crawl ghillie {padding in the front instead of jute or burlap} or just hood), what style of camo you want for the ghillie, what type of scope you want, what type of bipod.
But that would be for the lazy asses and if they can't spend time doing things themselves, then they shouldn't be airsoft snipers at all.
