I will have the first batch of the Cro's Nest here next week. I've test fitted the first few samples and they are superb. These are investment cast and there is very little machining required. There is a lot more going on here than just cutting the ears off a stock clamp. I will officially start rolling these out in the store in the coming weeks and will give a full break down on specs. I am up to my ears with the BF4 build so with a few exceptions, I will not be filling orders on Cro-Bars till after Born Free when I can devote more time to parts development. Most of the first batch of clamps are spoken for, but if you are interested in more info or a future order please email email@example.com.
