u/FabiusBill

I'm looking at buying a bore buddy upper to setup as a .22 AR-trainer for my family, that I'd like to also use for some precision shooting.

Both the Green Mountain and Lilja barrels are listed as sub MOA capable. Is the Lilja barrel that much of an upgrade for the additional $400? Is it worth paying more to "buy once, cry once"? Or am I unlikely to realistically see a difference?
