I have the Model 16 FCSS Weather Warrior in 6.5 Creedmoor (which I love by the way) and I'm looking to get an extra magazine for it, but I'm having a hard time finding one. I'm looking for just the same kind it came with (not one of the 10 rd aftermarket ones) since I'll be using it for hunting. I found item #53217 at Cheaper Than Dirt and it looks identical to mine, but it says it's for the Model 16C/12 and also it doesn't specifically say it's for the 6.5CM. Any guidance would be much appreciated!
