Whats the process to convert a LWRC Six8 to a DI Six8? I know you need the fitting for the upper. Does LWRC sell it? To make the change, I'm thinking you would only need the upper receiver fitting, a new bolt carrier plus a DI barrel, gas block and gas tube. But I'm wondering if the inside of their upper is milled where it would only work with their Six8 piston BC. I picked up a Six8 SPR that seems very accurate but will swap the barrel for an ARP barrel if needed and can be done. Just thinking outside the box.
