Yeah I'm seeing someone there that thinks they built a great gun, and I'm sure it's pretty good, but for that price it should be LMT and LaRue through and through.
Go build it yourself and spend the left overs on ammo or an optic
The Masada is going to be all that and a bag of chips if you believe the hype (yup I feed into that

) but it's going to be around this time next year before we're getting our grubby little hands on them without paying through the nose. Not to mention, if you're going to drop $1600-$1900 on an AR and you don't get a Piston upper or a Custom Match gun... you're just plain silly and have too much money to toss around.. in which case I would insist that you adopt me and give me all the spare money so I can continue to feed my guns.
