Lilja barrels out of spec ?

[olde sarge]

LRRPF52, thank you for your reply and the replies of all others. I didn't want to start trouble, just wanted to know the facts so I could purchase a barrel knowing the facts. I will ask for certification as you suggest and hope they will do it. Being new to AR type actions I have found all of this very confusing and a little overwhelming and am grateful to all that have answered my questions. I have read all I can find for the last week and there is so much on the web I am sure I have missed half of it. Thanks to you all I feel I can make pretty well informed purchases. John
