I picked up one of the brown M4A1's from them a couple weeks ago too, it instantly became my favorite gun. I fondle and practice dry firing it with snap caps daily, and even managed to hit the 200m gong at the range with just the irons on my second shot after sighting it in. Shoots like a dream...
I already want to get one of those V7 LW's now too and an MK18..... or maybe something from BCM, or a Barrett rec7 if I can save up the loot, all i know is I want more AR's ASAP haha. Wolverine was awesome to deal with, I got the Emtan folding BUIS from them and co-witnessed them with my Aimpoint T1, they're great and reasonably priced if your looking for some back up irons. Enjoy your new rifle man!
