I went with the sawtooth arca rail,and a warne skyline bipod, so far so good,shot a nrl match with it, did better than I thought I would but still had some manipulation of the bolt issues and just over all getting use to it,its really like shooting my centerfire rifles,without the boom,,,lol i think it's great, i just need to shoot it ,it only has about 300 rnds through it. I don't think I will be looking at a chasis system anytime soon, it just fits and feels like my other boom sticks. It is worth the wait and $$$ glad i did it, now my wife wants one.
