My hang up personally is that Magpul forces you to spend more money to get something up to the same capability as some other stocks, like the BCM Mod 1. Yeah, the stock is cheap and light but if I need to spend more money to get qd mounts that lessens the value in my eyes. I'm also not sure I'd fully trust a $10 MIC amazon qd mount but you can find some quality USA made ones around $15 or so. So in my head, it's not really a $40 stock, it's closer to a $60 investment now to get it to where I want it, possibly more, for a loose fit and weird molding pockets. $20 more nets me a BCM thats the same weight, has a tight fit, two built in QD mounts, a nice clubfoot, and a generous storage compartment.
Also during SHOT I believe I remember the Magpul rep in one of the vids saying they're working on a version that will have a tensioning feature and some other upgrades. It'll be interesting to see what they bring out.
