Purchased this rifle...
Purchased this rifle just for range use. The iron sights are a plus as most AR type rifles do not come with any. I do not use a scope so it was nice to be able to shoot right out of the box although the iron sights that come with the rifle are not the best I have ever used. May be swapping them out in the future. No issues with operation and cleaning is easy like most all AR styles. I have not used many different loads or brands of ammo but this rifle eats M855 without any problems.Fun and easy to shoot plus ready for any add ons you may want.

Great firearm. I have ran about 800 rounds through this of carrying weights and have had zero issues. Put JP reduced weight trigger springs in and it's fantastic. Buds was awesome, I will not buy a firearm from anyone except buds.
