I have the LMT SOPMOD on one of my non-SBR ARs and it's a dream to shoot. No, for real. It's so comfortable you could fall asleep on it. On my SBR I just have the standard LMT M4 stock. No issues yet, but I think I may move to a more shooter-friendly stock (maybe the SOPMOD) as I plan to hunt a lot more with it now that I've got a 6.8 upper and a Saker on the way too.
