We are proud to introduce Bartlein 400modbb prefit barrels.
The material has been proven in lab testing and in outside real world testing to provide a barrel life that is 1.5 to 2 times longer than the standard 416 grade of material.
As always there are a list of things that effect barrel life and we cannot guarantee everything a 100% but for an example as I know it will be asked….in 6.5CM ammunition pressure test barrels are normally pulled from service at around 1700 rounds. The new material doing the same type of ammunition test work the barrel was pulled from service after it had 3500 rounds on it. We’ve had several 6mm’s in calibers that the barrel normally is pulled around 1500 rounds go 3000 rounds.
We offer these Prefit Bartlein Mod 400bb Barrels for Seekins Havak, Terminus Apollo, Zeus, Helieos, Curtis Custom Vector, Vector full thread, Helix, Lone Peak Razor, Lone Peak Arms Razor, Kelbly’s Atlas Tactical, Accuracy International AT/MC/AW Defiance Tenacity Ruckus.
