My first Grendel / AR Stoner barrel / range result

[Tedward]

The piston is good for short barrel lead slingers. The department he works with bought them in Rifle length and he had to remove all of them and go to DI because of the lack of reliability. All the short lengths worked fine but the gas needed seemed to be an issue.

Anyhow, nice gun. also you have listed as NE N.C., up near the tide water???I'm in VA and go down to the beach and Nags Head so just wondering....
