NEW from Ruger, the LC Carbine is the next step in their line of 5.7x28mm firearms. A lightweight carbine with a 16.25” barrel but an overall length of only 28”-30” makes for an extremely compact package.

Weighing only 5.7lbs, this carbine is feature-rich, including a folding adjustable stock, rapid deployment sights, full-length 1913 Picatinny rail, M-LOK on the handguard, and a 1/2”-28 threaded barrel.

The heart of this carbine is the bolt-over-barrel 2-piece bolt design allowing for a more compact weapon while maintaining enough mass in the bolt for the fixed barrel blow back design.

Fire control group is identical to the Ruger 5.7 pistol and uses the same ergonomics with a 1911-style manual safety. This also means the LC Carbine shares magazines with the Ruger 5.7, giving some much-appreciated cross-compatibility. 

Iain Harrison got to give the Ruger LC Carbine a little test drive and found the trigger to be a “long mushy pull with indeterminate break point, long, indistinct reset, and all the overtravel you could ever want.”

While it might not be a precision marksman's weapon, the telescoping bolt and compact design are practically begging to be SBR’d into an even smaller format. 

Ruger will be offering the LC Carbine in 3 models to start, but they are effectively the same. The main model is full-featured and comes with one 20-round magazine, the second model has a fixed stock and a 10-round magazine, and the last model is full-featured but comes with a 10-round magazine. If you’re in a more restricted state, hopefully, one of these models will be for you.
