AR-15 Review of Olympic Arms AR-15 K16 5.56 Nato specifications are as follow:
Gas Operated Semi-automatic Action, flat top with picatinny rails, 16″ bull, button rifled, 4140 chromemoly steel barrel, 1×9 Twist rate, Crown muzzle, length is 34.375″, 7.47 pounds in weight.
I have been using the .223 round rather then the 5.56 Nato round. (A bit less expensive). It comes slandered with features like a bull barrel, flat top upper, free floating hand guard, rail gas block and A2 butt stock. With all that said this AR-15 is a blast to own and shoot. Using the .223 round you can not feel any kick. At least I can’t feel a kick. Mine came with 2 30 round magazines. Chambering a round is pretty easy once the magazine is in place. Pull back the receiver rod and push the button on the right side and you’re loaded. Changing out the bolt assembly and upper receiver to allow for a different size round is simple as well. My plans for the future are to get the 308 bolt, chamber and upper receiver some time in the future. The Olympic Arms AR-15 also has a safe and fire selection switch on the left side. With the selection switch, the need to pull back the receiver and push the cock button on the right, I would feel safe having this weapon out around young children. Also the fact that it ways almost 8 pounds on top of it sure does help.
