Guys, I need some input on this. I found a brand new MKII less the upper receiver and barrel, so really just the lower receiver, bolt, and mainspring housing. I got a Tacsol Paclite receiver/barrel and put it together without issue. It will not cycle at all with standard 'bulk' ammo such as the Federal and Winchester found at Walmart. I tried some CCI mini mags and it cycles fine.
Are these normally that finicky with ammo? Does it need some break-in before working with standard ammo? Comparing it to other MKIIs, mine takes a little more force to initially move the bolt rearward (unless the hammer is already back). I've cleaned everything, and tried running it both dry and lubricated.
