12-10 - Manufacture date

thx. gwp
is a 1-10 twist rate standard?
"I eat concertina wire and piss napalm and I can put a round up a flea's ass at 200 meters."
yep, for M1 anyway..
anything special to know about breaking in a new barrel?
i don't suppose they did anything special during the big one.

Goo,
I've installed two new Criterion standard M1 barrels.
All I did was swab them out with Hoppe's after each range session like I would any barrel.
They had me a little scared at first, not holding black at 200 yards, but after about 75 rounds they really settled in and are equal to or even better than a GI barrel.
Hope this helps.
Chris.
thank you much, crispy.
