The Chiappa Firearms company is at it again: here comes the MFour-22, a nifty rimfire replica of the current U.S. military issue carbine!

The flash hider on the MFour-22 carbine is simulated, but it can be replaced with a real one simply by removing a locking screw

The front sight can of the MFour-22 carbine can be adjusted, just line in the original M4 carbine

The polymer handguard consists of two halves, just like the original, but doesn't feature the classic aluminium heat shields

The carrying handle of the MFour-22 carbine is mounted on a Picatinny rail; according to the markings, this sample was not made at the Chiappa Firearms' plant in Italy, but at the Chiappa Firearms USA plant, headquartered in Dayton (Ohio)

The controls configuration on the MFour-22 is just the same as in the M4 carbine: only the hold-open lever is an inert reproduction

The forward assist button on the MFour-22 is also a reproduction, but it's spring-loaded, so it can be pushed to simulate the feeling of a real forward assist - for training, so to speak

Some small parts are reproduced with an utter level of faithfulness: that's the case for the cocking handle and the rear sight of the MFour-22, both made out of polymer

The MFour-22 upper receiver is a flat-top, featuring a reinforced polymer MIL-STD-1913 "Picatinny" rail

The Chiappa Firearms MFour-22 replicates the original M4 even down to the dust cover

Although it's polymer, the top Picatinny rail on the MFour-22 is sturdy enough to accommodate any gunsight - including this Leupold Prismatic

The pistol grip of the Chiappa Firearms MFour-22 carbine is just the same as found on any M4-type carbine, and can be replaced with any similar aftermarket piece

The magazine release system of the MFour-22 carbine is not of the "drop-free" type: as the mag release button is pushed, the magazine itself must be manually pulled out

Franco Palamaro

Magazine capacity for the MFour-22 may range between 5 and 28 rounds, according to laws and regulations of different jurisdiction

The fixed stock of the MFour-22 carbine is a simulation of a standard M4 collapsible stock, but with minor modifications, the rifle may be fitted with any aftermarket M4-type stock system

Chiappa's MFour-22 carbine is a bliss to fire, totally controllable albeit remaining very realistic to handle!

Stripped down to its main components, Chiappa's rimfire MFour-22 shows all the similarities with the M4 carbine

The die-cast bolt group integrates the recoil spring and guides, and frankly reminds us of the famous Ciener-Atchisson conversion system, particularly as far as it concerns the stamped steel guides

The lower receiver of the MFour-22 carbine is made out of molded reinforced polymer, and is a 95% perfect replica of the original - some differences have been retained on purpose to prevent it from being 100% compatible with a standard 5.56mm/.223 M4 upper receiver

Chiappa's MFour-22 carbine, seen from the left side: the trigger group on this carbine is basically a 100% faithful reproduction of the original M4 trigger group, and even the safety switch works in the same way

A right side view of the MFour-22: it's such a high-grade reproduction of the original M4 that it could be used for basic training!
