The night stalker is actually designed to be rear heavy to compensate for the additional weight of a forward mounted clip on. To acomplish this, the shell is designed to be very light, strong and rigid before hardware. Fully inleted before hardware is only about 20 to 22 ounces. Once the adj butt, cheek, efr rails with cups, 7" arca rail and dual pic rail are added, they will come in at about 2.9 lbs with a very rearward balance point. Thus is the same concept that we use on the big competition stocks like the king of 2 mile gen2 stock, by making a super light weight shell and adding the weight in the rear hardware , the overall weight stays lower, but the balance point is moved that will offset the additional weight of the night vision, or in the case of the big comp guns, a 34" long 2"dia to 1.1"dia super heavy barrel.
