ATTENTION BEFORE READING------ I am not an operator, I am not a police officer, I do not have plans on going into combat, I have general marksman skills, I plink cans, paper, junk and coyotes. I don't go to rifle courses. I fully understand there are better quality AR's out there. I dont make enough for a 3,000 dollar AR and dont put 3,000 dollar AR's on my credit card. That being said, this is my rifle and I love it. It makes a nice addition to my Smith M&P15 Took my recent build to the range today. Its a JD lower, PSA lower parts kit, Model 1 A2 stock with a DPMS 20" A2 upper. I built this rifle for about 670 bucks. Before the range it was cleaned, oiled and greased. I also leveled the front site post and midlined the widage adjustment. I put 140 rounds through it today including PMC 55grn FMJ, Winchester superX 55grn pointed soft point, and 50grn Remington UMC hollowpoints. It shot great. It started with a tight group 4 inches low and 1 inch to the right at 50 yards. It took 9 other shots in groups of 3 to bring it to zero. The sight adjustments were sturdy and solid when adjusting. I was very happy to see how tight the groups were for this gun. I did not do any special barrel break in procedure, I also did not rapid fire the crap out of the thing either. Not that this was some kind of torture test, but the rifle had zero stoppages of any kind. I do not shot 3,000 rounds a week, I shoot more like maybe 1,000 to 1,500 a year. If something goes down on the rifle I will upgrade the part, but right now I am going to shoot and enjoy this sucker. The gas key appears to be staked well from what I can tell. All the brass kicked out at the 4oclock positon about 10-12 feet away from me. Ok DPMS haters lets hear it.................... Wanna kill these ads? We can help!
