AR bolt/gas-key question.
Can you use the bolt from a piston AR in a DGI gun?
I know that a common problem with DGI ARs is that the gas key can shoot loose. I see that the piston ARs have that part machined into the bolt as a single piece, and are therefore much more durable to endure the stresses of repeated piston strikes. Can I buy a piston style one-piece bolt and use it in a DGI gun?
