Same source claims LWRC lost their lawsuit against SIG. Any one have actual scoop on these statements?This from an insider. The 516 is a shameless and improved copy of the HK416. It was designed and built by the same people...many of them anyways...that designed and built the HK416. These guys were hired away from HK, paid more, and told to make the best rifle they could with all their experience, and without the working environment they came from. The result is in my opinion, the pinnacle of M4 development, as only the Swiss can make it.
