I have a JP trigger on the way and I was looking at their website. Does anyone have any experience with their heat sink, hand guards or barrels. I am in the middle of building a varmint gun and am still looking for parts. I think the blue heat sink under a black set of vented hand guards would look good. The heat sink would help to keep the barrel under the hand guards cooler, which I would think that would be good during a day in the South Dakota sun. Thanks. eagle308us
