16″ Rifle Gas Competition Setup – Adjustable Gas Tuning
We have tested the following configurations to determine optimal port sizes with this barrel using the MicroMOA Govnah for various common competition configurations. All testing was done with little to no lube and in Florida during summer temps. Ammo used was green box Remington Value Pack .223.
