I gotta agree with Grant here. Those M-4 cuts just look plain shitty. Functional perhaps but I'd never accept it. More importantly, that gas key way is totally unacceptable and stands a very good chance of coming loose.
To say that hey all these guys are just hobbyist who only shoot a few hundred rounds through their piece is a poor attempt to excuse a main line AR mfg. of shoddy workmanship. If we all said, hey my customer is just a hobby guy so I can slack on the quaility of my product, it would be a sad state of affairs.
