Just out of curiosity, how many rounds did it take to start seeing signs of keyholing?Last time I was at the range shooting the Max11-15 I noticed the holes in the paper started looking oblong. What’s a good replacement barrell for this upper? Anybody have any advice or input on the process?
Good to know, thanks.I don’t know exactly…just a guess but maybe 10K-12K?
we are talking about 5.56 barrels. 10-20k is pretty good IMHO. I do have 9mm barrels with right at 100k on them and they are goodWoW little 9mm and such a short service life barrel smh?
Why can't they make barrels out of much better superior materials... I would pay far more for far better.
IMHO 100K 9mm barrels should be really possible WTF? Yes I understand about heat and pressure etc. etc.
