Actually, I plan on a carrier dedicated to the Grendel so I'm not always having to put one rifle out of service to benefit another. There's just so many different styles to choose from and I am seeing cheap prices on some of the more generic ones, modest to fair prices for other plated carriers, but I have read reviews that make me want to stay away from chrome. I have also seen some stainless carriers and a whole stampede of other special plated carriers and I have looked at Brownells, Cheaper than Dirt and Midway, Stag, Area 51, Gun Broker, DPMS, Natchez, and a few other sites. I planned on spending more on this build and I want parts that last, but I'm thinking stainless seems a bit soft for a carrier system that's going to be slamming back and forth. There are a few other styles and platings offered, but even those reviews are either vaguely positive or non-existant. Brownells has some fair priced carriers but I don't know anything about some of those models and have yet to read the reviews, (If Any), on a few that I liked. About the only carrier that got a good rating is a bit pricey but doable, is the Titanium. Has anyone had any experience with the Titanium carriers? But I did like your idea about the gas block. I will be tinkering around with that this weekend.
We may also be shooting some this weekend, so maybe we can get another video up soon.
