Stag Arms is updating its Stag 15 lineup with a bunch of new rifles, uppers and rifle kits, including the Stag 15 Valkyrie chambered in—you guessed it—Federal’s 224 Valkyrie round, and the Stag 15 M-LOK SL handguard. Full presser below.

Stag Arms, LLC, will introduce its refreshed Stag 15 rifle series at the 40th annual SHOT Show in Las Vegas, NV. With more than 10 all-new right and left-handed series of rifles, upper halves and rifle kits.

The focus of the new Stag 15 series is the company’s newest handguard, the Stag 15 M-LOK SL, featuring a slimline, lightweight profile that offers increased ergonomics, maximum airflow, and modularity while continuing to provide the utmost strength and durability.

The new Stag 15 series, along with its latest addition, the Stag 15 Valkyrie, will make its debut at the Stag Arms Booth 20349.

The Stag 15 Valkyrie utilizes the all-new 224 Valkyrie cartridge, created by Federal Premium Ammunition, allowing for maximal performance from the Stag 15 platform.

Built around an 18” 416R Stainless Steel Fluted Heavy Barrel, the 224 Valkyrie cartridge provides less wind drift and drop than all other loads in its class and stays supersonic past 1,300 yards.

Stag Arms has also partnered up with Mission First Tactical and FAB-Defense to release two new Stag 15 Series, the Stag 15 Minimalist and Stag 15 TFD, respectively.
