Ruger SR-762 7.62mm NATO AR Rifle | Gun Preview
Piston-driven enforcer runs cooler and cleaner to deliver added, barrier-busting 7.62mm power!
Piston operated or direct impingement? This AR-centric debate will rage on for years, but Ruger has firmly planted itself in the piston-driven camp with its SR-556 series of rifles. And now the company has released a big-bore brother, the SR-762 in 7.62mm NATO. In the upcoming May 2014 issue of GUNS & WEAPONS FOR LAW ENFORCEMENT, author Richard Mann test-fires the new carbine and offers a full range report.
Mann writes, “The piston on the Ruger SR-762 is a two-stage affair that works behind a multi-adjustable regulator that has four settings. In the ‘0’ setting, no gas is driven into the piston and the rifle works like a single-shot, requiring the shooter to operate the action with the charging handle to extract and eject the fired case as well as to chamber a new cartridge.
“Ruger advises that the number ‘2’ setting will most likely offer the best functioning and reliability with most factory loads. The neatness of this design is that you can tune the piston system to work perfectly with the ammo you are using. If spent cases are landing well behind you (what is called ‘late ejection’), move the regulator to a setting with a larger number. This increases the gas port size and forces more gas against the piston.”
