Ruger LC Carbine: Lightweight Folder in 5.7x28mm

Check out the Ruger LC Carbine. Though a relative latecomer to the lineup of 2022’s new guns, the weapon has generated quite a response from fans of both Sturm Ruger and the 5.7 cartridge. It is chambered in 5.7x28mm and utilizes Ruger-57 pistol magazines, and it uses the same fire control unit as Ruger’s 5-7 handgun. This sort of cross-platform compatibility is becoming increasingly common among new firearm designs and will doubtless make both the carbine and its pistol predecessor more appealing. At least to those who might have been on the fence about the handgun anyway.

If you’re wondering about the magazine well, it doesn’t have one. The Ruger LC carbine uses bolt-over-barrel design with the magazine inserted via the pistol grip. It also features a folding (adjustable) stock and collapsible sights (q.v.).

The Ruger LC carbine is chambered in 5.7x28mm; Ruger calls it the "Perfect Range Companion".
The LC carbine has also been welcomed by the usual crowd of dissatisfied naysayers and disaffected critics, of course, but that’s to be expected. Someone could release a working version of the M41A Pulse Rifle complete with functional 10mm caseless ammo and there’d still be people who’d bitch. “The ammo color is the wrong color!” “No one can afford that ammo, I has disappoint!” “I’m nervous and my socks are too loose!” But I digress.

The new Ruger carbine uses a bolt-over-barrel design, thus the mags feed via the pistol grip vs. a magazine well.

Ruger tells us in their release, 

“The compact nature of this carbine owes to its bolt-over-barrel design and feeding through the grip.  The Ruger LC Carbine has a full 16.25” barrel, features a reversible side-folding stock adjustable for length of pull, and is compatible with Picatinny rail-mounted accessory stocks.  The stock and Rapid Deploy adjustable sights can be folded for storage.”

Ruger also avers that the LC’s felt recoil is comparable to 22lr, even when using 40gr 5.7mm cartridges.

They go on to say, 

“Like the Ruger-5.7 pistol, the LC Carbine utilizes Ruger’s safe, reliable and proven Secure Action fire-control mechanism that combines a protected internal hammer with a bladed-safety trigger that has a short, smooth pull, clean break and positive reset. The fluted, nitride-coated alloy steel barrel is durable and lightweight and allows for the attachment of standard muzzle accessories.”

Ruger's 5.7 carbine features a left-folding stock (i.e. inboard for right handed shooters).
