I just found a good deal on mini 14 series 583 law enforcement stainless rifles .I just read a review a guy did on series 583 and he had problems with the bolt and gas system .He rebuilt the rifle and added the stabilizer and got 1 inch groups .Has anyone had any experience with these 583 le models .Its a good deal if it's good but a lemon if it's bad .I read they were made in 2017 so it should not have fired a million rounds through it .
