Ruger Enters 5.7mm Carbine Race
Ruger this week expanded its 5.7mm offerings by introducing a lightweight carbine to complement the already popular 57 series pistols.
The new Ruger LC Carbine in 5.7x28mm is compact, with a threaded 16.25-inch nitride-treated steel barrel and a side-folding adjustable stock keeping it short. Weight, at 5.9 pounds out of the box, is kept low via an aluminum alloy hard-coat Anodized receiver and synthetic furniture. Logically, it uses the same 20+1 capacity steel magazines and ergonomic controls as the Ruger 57 pistol.
The company says that using typical 40-grain 5.7 loads, “this high-performing carbine’s felt recoil is comparable to a .22 LR.”

The reversible folding stock, with adjustable length of pull, is compatible with both AR-pattern and Picatinny rail-mounted aftermarket accessory stocks. Speaking of Picatinny, note the full-length top rail and adjustable flip-up sights.
