Excellent, slinder, DEAD eye

I had purchased this, and it came I believe on the 28th day from the day I ordered it, exactly what they told me it would take. Let's start with the packaging, the upper came inside a craft cardboard box with nothing more than a shipping label on it, discrete. Inside the craft box was the actual box; white, SpecOp's MFG Logo, large Made in the USA with flag, taped with a tamper sticker. Opening the box, there was nice bunches of bubble wrap wedged on each end of the box. The upper itself was sealed in a plastic condom. I ordered a Nickle boron BCG and milspec charging handle with the upper. The BCG was inside a cardboard tube sealed with end caps (it was beautiful and absolutely perfect inside and out). The charging handle was in a little plastic baggy. My receipt was signed by a lady and a happy face was left on it. Un-sealing the upper, i could tell it had been wiped down with lubricant, the lugs and chamber where silk smooth, the rifling was crisp and uniform (slight spec of rolled up lubricant down the rifling out of the condom), the flash hider was slightly off center, but it wasn't nearly torqued down on the crush washer, the forward assist works perfect. The alignement of the M-lock rail was perfect (I could see they used anti-seize at the locking points for the rail and upper receiver), the gas tube is nice and shiny with the matte black finish (anodizing is great). The brass landed in one place each time, so i suspect it is properly gassed. My first impressions: I was crazied over how skinny it was!! Felt so light, and really stiff. I can wrap you entire hand around the handguard and more. The barrel itself is nice and sturdy and the gas block is pretty damn small. I couldn't set it down when I first got it. With a complete rifle it is very light, very weildable and manageable. I am extremely pleased with this product, I am very please with the bolt carrier group they made as well, it is so nice... so smooth, and wipes clean with minimal effort. Great work SpecOp ,God Bless America, God bless us all, life is good.
