I have a friend who is heavily involved in the firearms industry, engineering guy, knows his shit by a long shot. I was actually asking him about a rifle build when he turned me on to JP. He informed me that he had purchased two OBR's but he could not get them to perform like he believed they would. He said he attempted to address the concerns with LaRue, but that did not go as well he thought (this was a few years ago now). In frustration, he replaced all of the barrel and guts of both rifles with JP products and then obtained the performance he was expecting.
On my buddy's recommendation, I purchased a JP. I own an LRP in .260. It shot so well and I was so impressed with it's accuracy, I ended up grabbing a JP15 in 5.56. There is no doubt about it, they are precision rifles. The other awesome aspect of JP rifles is their gas system. They make it very easy to stay on target or make your own corrections.
I'm not saying this to talk shit on LaRue products, I think they make great rifles and I will own one or two at some point. After what I have personally experienced with JP's products, it is easy to recommend them for a precision semi-auto.
Grab the JP, if you're disappointed, sell it and get the LaRue.
