What do you plan on using it for? If just for a casual plinker, I'd also recommend taking a look at the Magpul Backpacker version. After going through this same decision recently, I received my backpacker pc carbine this week and put a red dot on it. I like the magazine storage compartment in the stock and the way the carbine stores into one piece, plus this version doesn't feel quite as forward heavy as the other models. It might not be as versatile for adding accessories like one with the M-Lok forend, but still has that capability. I also personally like the appearance of this version over the other versions, but that's just me.
