To each there own. I own both the older and new variant hk stocks for 416/223 and they both are great and so is the Sopmod as well.I'll trade my slimline stock for a LMT anyday. For a $4000 rifle, I expected something better IMO. Even a Magpul CTR would be an upgrade. I don't get sucked into the HK coolaid. Don't get me wrong though, my MR223a3 is a heck of a rifle but the stock is a huge dissapointement
For the MR308 I only have the first version. I might get the stock when I get around to buying the MR308 A3 but that will be in G28 version first. I would like a 12.5 MR308 as well though.
