So what can you guys tell me about this spartan upper? Been reading reviews seems ok. Non reciprocate handle. Price is decent. Thinking about putting one on my next build maybe build my first piston driven ar. Would be shooting suppressed mainly, the piston driven would stay cleaner. Also they claim this side charging upper cuts down on gas back pressure from being as bad while shooting suppressed. I like everything about it except no dust cover. I believe this can be used with di or piston. Opinions please, what do you think?
