Excellent article! I completely agree. I've had mine a couple of months now and don't understand the issues some others have. Accuracy is totally amazing...just wait until you try reloads. I will add that I replaced the stock with one that slides on rear bag in recoil. Also agree with difficulty in mounting mlok...seems this could easily be improved.
I put a piece of skateboard tape on the toe of the SOPMOD stock to create a non-skid surface so the bag wouldn't slide around, seemed to work pretty good.
