I just seen one at a gun show - I wouldn't use it and M4 in the same sentence. It 'resembles' an m16, however the handguard is fugly, the grip is fugly, the finish is greyish/blue. In photos it looks 'ok' however up close and personal - I'd pass. Its the 50 year old whore of chinese AR's. Not my thing, but I'm sure some guys still love it.
I hear they shoot great though.
