18” SS fluted ultra match 6mm ARC barrel
Rifle +1 gas length - I have an extra new gas tube I will include. 1:7 Twist
Replacement from Rainier Arms for another one that had pitting and shot 2-3 MOA.
Gun didn’t cycle reliably. I had to drill out the gas port from the factory because they didn’t drill through all the way. Ended up over sizing it and using an AGB to ensure it actually cycled.
Lapped receiver and bedded barrel with Loctite - shot 1.5 MOA on average. 2550 with factory 108 ELDM.
Always heard good things about these barrels - could never get mine to shoot well consistently. Maybe you will have better luck, I’ve given up on anything from Rainier Arms
