Will these springs make ur rifle more accurate, no. Will they improve ir shooting skills or speed up ur time, no. But, this is definitely the kind of upgrade u wanna get if, like me, u pay attention to the smallest details & having the best quality in ur builds, right down to ur detents, matters to u. I love trying to make my builds as custom/unique, smooth & accurate as possible. & these springs definitely add a little extra quality feel to ur magazine realease. The movement is smooth as glass & I can tell a significant difference between these springs & Milspec. When u compare the 2, the 1st obvious difference is the finish, these being much smoother & made from different material. 2nd u will notice that these springs have much less side to side movement than a milspec spring when u compress it with ur fingers. IMO, these springs are a no brainer for the price. Plus u get 3 of em, so now 3 of my ARs have these smoother, upgraded springs.
