This durable 6.5 Grendel (6.5x38mm) magazine is built for long-lasting and reliable performance. The use of .020 gauge stainless steel combined with increased interior dimensional room enhances proper stacking of the rounds and reduces failure due to jams. The polymer anti-tilt follower keeps cartridges aligned while the high-quality chrome silicone springs ensure consistent feeding shot after shot. The finish is a durable matte black coating that is resistant to the elements and slightly self-lubricating. It also helps reduce glare for stealthy operation. For use in Ruger American Rifles® chambered in 6.5 Grendel only. Made in the USA by C-Products Defense. *Due to changes in the law effective October 1, 2013 Ruger is not able to sell magazines to CONNECTICUT residents.
