What began in North Carolina as a parts and accessories supplier for America’s modern sporting rifle, Del-Ton Inc., now supplies a full lineup of turn-key, semi-automatic rifles. The company’s Sierra 316L, subject of this week’s video preview, provides the versatility of a modernized AR-15 platform while maintaining a cost-conscious approach.

Del-Ton supplies 7075 T6 aluminum, forged upper and lower receivers that are hardcoat anodized for a matte black finish. The flat-top upper is configured for right-hand ejection, along with a forward assist mechanism and ejection port cover.

The Sierra 316L features a 15” handguard, and thanks to Magpul’s MLOK mounting system, users can simply accessorize as needed. Del-Ton supplies a lightweight profile, 16” barrel. A twist rate of 1 in 7” is supplied and the barrel is threaded and fixed with a birdcage-style flash hider.

The gun’s lower is configured with standard, no-frills controls; a two-position safety selector is found on the left and on the right side is a magazine release button. The gun’s mil-spec buffer tube is fitted with a five-position collapsing buttstock. Provisions for sling attachment are found here, too.

If the gun-control Left is to be believed, then the murder rate in the U.S. should be going up. After all, gun sales and ownership rates have been rising for the last few decades and anti-gun groups claim that gun ownership is the cause of violent crime. This, of course, is nonsense.
