I have a question on barrel life for the Grendel.
How long will a barrel last for a Grendel?
Will the round eat it up?
See I shoot alot, not competativly (not yet al least) and my 223 barrels last forever!
I love everything I read about with the Grendel, just want to make sure it is not high maintance?!
A Grendel barrel will last a ling time. Possibly longer than your 5.56 tube. I'm sure some of the other guys will correct me if I'm wrong on that last, and they can give you more info as well.
Probably depends somewhat on the quality of the barrel, but ~5k+ seems like a reasonable expectation for the top-quality barrels to maintain respectable accuracy, especially if used primarily for deliberate shooting without heating things up with mag dumps.
Generally speaking, I don't think the 6.5 bore at Grendel velocities is terribly hard on barrels. Shrink the bore and increase the speed, such as the case with some of the 6mm Grendel-based wildcats, and life expectancy will likely decline.
If you go by the chart here http://www.accurateshooter.com/techn...ed-by-formula/, theoretically the Grendel should offer longer barrel life than the 5.56. Additionally, the Grendel runs at a lower pressure than the 5.56.
So no rapid heavy firing?
Not that I do that. That's for my MP15-22!
So look for a good barrel?
Any suggestions on an upper?
AArms? Do they math up well with other
Companies lowers. I was thinking of Rick river or a
Thanks for the link that is a good one.
wojo14, I like rock river lowers a lot, I am looking at a J&T upper but I have never used one, the price is right however, http://jtdistributing.net/store/page148.html
Welcome, OS. You wouldn't happen to be the same Old Sarge on the FAL Files, would ya?

Are they 6.5grendel bolts?
whichever brand you decide spend the extra and make sure the barrel is nitrided it will extend the life even longer,stay away from any chrome lined barrels
I just got my j&t kit fit and finish is good. They do use a 6.5 bolt not the 7.62 bolt.
