Pattern 14 subject to cracked barrels??

[Chuckindenver]

have yet to have to cut a shoulder on a 17 or 14. Criterion makes a nice P14 barrel, i have installed many of them without any issues..
never seen a cracked barrel, have seen several cracked receivers, all from damage other the crush pressure.
most likely using primitive tools to remove and install, or using the right tools incorrectly
