Its a cool novelty, but shootability suffers from the light weight (think why national match guys will put lead weights in their guns, heavier is steadier. Don't be a retard and have a 15lb shtf rifle, but 7ish +/- 1 is good place to be) also Ian and Karl are fags, ian is a good historian and thats about it, Karl is a huge tool who can shoot decent at a club level but talks like he's a world champion. Also non captured pins is big ghey, Colt did a threaded takedown pin so it wouldn't fall out without having the need of a detent 20 years ago, and Colt couldn't keep a company that had the biggest reputation in America in the black. There's not even a hoke in the stock to be a poor man's hk. Will say good on them for keeping the price point they said they were, and the lowers themselves would be decent to play with, but they built a service rifle and ignored almost every update the army did to make carbines more effective, no provision to mount ir, limited railspace, the heavy barrels weren't for accuracy they were for sustained fire, and the scs is nice, but I'm sure its been tested, and passed over in favor of a regular heavy buffer system, or the a5. And no matter what they (Karl) says unless its exclusively kicking doors then then usasoc tends to like the highest ability to get a pid as possible, so red dots are a secondary sighting system in favor of lvpos. Ok done sperging, its a neat gun and they're pretty decent as far as components, but I wouldnt consider it a serious use in any sense.
