Barrel steel quality and hardness will be the main contributing factors to barrel life, all things equal. With the Grendel, chamber pressure is so low that we don't plasma blast the throat with converting propellant at higher pressures like a lot of other cartridges.
Mark will make you a concentric, very clean Krieger Grendel pipe and his uppers are one of the top billet upper receivers on the market. Receiver faces are square, and fit with his billet lowers are superb.
His ammo is really top-end as well. I was getting 7fps Extreme Spread with one of his 123gr Scenar loads years ago, which was my first exposure to his products.
