It used to be that the FN 5.7x28mm round was an exotic beast. Guns chambered for it were few and far between, and ammo was expensive and hard to find. A lot has changed over the years, and there are a lot of 5.7 options on the market now. With guns and ammo readily available, it makes sense to have a dedicated cleaning kit for the caliber. So that’s just what Otis did with the Otis 5.7mm Rifle/Pistol Kit.
The Otis 5.7 Rifle/Pistol Kit

Otis has made compact cleaning kits for various calibers for quite a while now. They come in a rugged, zippered nylon pouch and are caliber-specific. The kits have all the tools necessary to clean and maintain your rifle or pistol in the appropriate caliber. I carried an Otis 5.56mm in my patrol rifle bag before I retired from my county police job. Otis now offers a dedicated kit for the 5.7x28mm caliber.

They actually list two of them. A Rifle/Pistol kit and a Subgun Kit. They’re very similar with some minor content differences. My case says Subgun Kit, but the actual contents are those of the Rifle/Pistol kit. My only 5.7 currently is a Palmetto State Armory Rock pistol. I got a killer deal on it with the gun, 10 mags, and a soft case. I’ll eventually add an SBR or carbine to the mix, too. Either way, it was worth getting a 5.7 kit that I could keep with my 5.7 gear.

What You Get
The Otis 5.7 kit comes in a pretty nice reusable plastic case. Although the case contains a black, heavy-duty nylon pouch that holds the kit, I’m not sure you’ll really need the plastic case anymore. I’ll save it for something else. It’s a lot nicer than a cardboard box or plastic clamshell packaging.
