they might mean mod as in spending over 500$ to make it sniper worthy but ur might need to MOD the but plate so it fits ur style. word of warning! sniper rifles are a bad FIRST gun to enter the game of airsoft. stock airsoft snipers are just as accurate as stock aeg's. Some players may not like you to use a sniper rifle because of trust issues.
saying that you might wana watch out when hitting or bumping this gun because it looks flimzy but im not sure because i do not own the gun :P if u own the AWM version. If you own the other one then try and find a tight bore to make it more accurater
