Funny there is that over here in California I can order any REAL barrels, gun parts, etc, and ship stuff in the mail (as long as it's not the serialized bit, like an AR lower). Being an Aussie it's still unusual to get a full AR upper receiver mailed to you (but I am not complaining).
Anyway, taking us off topic, just glad people are getting their kits - I did the sharpie marker on mine to darken the grips and it looks great! Also put a cork washer in the front to get a tighter lockup on the bolt action, and bent the trigger spring a little to get a more consistent reset.
My hero blaster now sits right next to the functioning Logan's run DS blaser. Quite the combination.
