The newest high-speed cartridge developed for the AR-15 platform was just released by Federal Premium Ammunition in the form of the .224 Valkyrie, allowing supersonic velocity out to 1,300 yards.
A quick review of 2017 reveals that it was the again the year of the AR-15. But, looks can be deceiving. Here are nine new ARs that fire something other than 5.56 NATO.
Fitting of its name, the Minimalist is a svelte AR with just enough features to make it eminently practical in the woods. Weighing 6 pounds, it’s lighter than almost any centerfire bolt-, lever- or pump-action rifle you’ll see at deer camp.
Chambered in .300 Blackout, the new MSR 15 Blackout from Savage Arms uses a pistol-length gas system, allowing users to utilize suppressors and reliably cycle subsonic ammunition without adding length and weight.
