My thoughts.
1. MEGA lowers aren't high dollar, and I don't know of any companies off hand that use them in high end builds. Doesn't mean it's not a quality weapon, but for 3k, i'd expect to see a "better" name.
2. "Snipers" don't generally use collapsable stocks. Think about it.
3. That may be a "match" barrell, but it's not something a "sniper" would use. Go on cheaperthandirt.com or some similar website, and do a search for "sniper" in firearm accessories. The catalog will be full of useless crap, just like that bipod.
4. Like Brian said, you could build that yourself for less than 1k, then throw a quality scope on for about $400.
People love to say "tactical", and "sniper" when they sell ****. Don't fall for it. Unless you're a trained long range shooter, any decent barrelled (20 or 24 in) AR with a scope will suffice for %99 of the shooting most of us want to do.
