Originally founded by Ezechiele Chiappa as Armi Sport in 1958, Chiappa Firearms is an Italian-owned and operated arms manufacturer based in Brescia, Italy. Bringing a wealth of knowledge from his work with a manufacturer in Valtrompia, Chiappa's natural technical abilities gave him the skills necessary to form his own company, a company that would produce only one pistol for its first four years before growing into the respected industrial corporation that it is today.
Today Chiappa Firearms is just one component of the Chiappa Group, the aforementioned industrial corporation that includes Armi Sport (replica firearms, target shooting and defense), Kimar (blank, signal and small-caliber firearms), ACP (laser training systems) and Costa (metal surface treatment). It is still family-owned and reliant upon innovative design work and modern manufacturing, two traits that Chiappa believes are key to providing the world with high-quality firearms and components like the Chiappa M4-22 upper receiver.
As noted, the Chiappa M4-22 upper receiver ships as a complete conversion kit that allows users to easily convert their MIL-SPEC AR-15 chambered for either the 5.56x45mm NATO or .223 Remington cartridges into a rifle capable of firing the .22 LR rimfire cartridge without making any permanent modifications in the process. Developed as a cost-effective means for shooters to enjoy the AR-15 platform, the M4-22 upper receiver improves upon earlier drop-in conversion kits in terms of performance and reliability. This package includes everything needed for a full .22 LR conversion. Components include a flattop receiver, M4-profile barrel, bolt carrier group, charging handle and two 28-round magazines.
The Chiappa M4-22 upper receiver features, as noted, a 16-inch barrel (1:16 inch twist rate) with an M4 profile and is forged from 4140 chrome-moly steel. The barrel is joined by a flattop upper receiver constructed from polymer that includes a Picatinny rail that allows the user to mount his or her preferred optics for long-range or precision shooting. Combined, these components make up for a total length of approximately 34 1/4 inches and weigh in at just 3 1/2 pounds. The numerous other features of this assembly include an M4-style front site, a bayonet lug, a two-piece plastic hand guard and an A2 birdcage-style flash hider. As noted, the assembly includes everything needed for a complete conversion, including a bolt carrier group, charging handle and two 28-round magazines.
