Really, the only downsides of the rifle compared to a name brand AR are as follows:
-Crappy finish. Painted aluminum. Can be corrected with GunKote!!!
-Metric threading. Really only an issue for the barrel nut, as a collapseable carbine stock can be made to fit (why you'd want one on a 20" barrel is beyond me, but I digress...)
- 1/12" twist rate. Allows 55grn to be stablized, but really nothing larger. Not a problem if you shoot surplus 55grn like me!
- lack of brass deflector - really only an issue for lefties like me, but the brass usually JUST whizzed by my face... only caught one or two...
Other than that, they are a fine start to the AR addiction.
