So if the piston AR is more reliable why isn't it in greater demand?
Can you buy an HK416 upper? I know you can't buy the entire gun.
What would be a comparable lower to pair it with?

Thanks for the replies.
Finding an HK416 upper is damn near impossible at times. They also are no better than the other gas piston ARs that are put out by various companies.
