Chiappa Firearms Mfour-22 Gen Ii Pro 22Lr 16 Adj Stk 28R$281.24
Availability: In Stock
The Chiappa M4-22 Gen II Pro is a .22 LR rifle that brings AR-platform ergonomics and handling to a fun, affordable rimfire package. Built as a faithful semi-auto replica of the M4 carbine, it's purpose-built for shooters who want reliable plinking practice, budget-friendly range time, or training in facilities that restrict centerfire ammunition. The 16-inch heavy barrel and 28-round magazines deliver plenty of trigger time between reloads.
If you've run AR-platform rifles, you'll feel at home immediately—the controls, charging handle, and trigger guard work exactly as you'd expect. The adjustable six-position polymer stock lets you dial in length of pull, and the removable carry handle with A2-style front sight comes ready to shoot out of the box. The Picatinny rail accepts standard AR accessories, so optics, lights, and handguard upgrades from your existing parts bin will fit. Polymer receiver and steel components keep weight down to 5.7 pounds, making it nimble for younger shooters, trainers, or anyone building a .22 platform for high-volume target work.
The M4-22 Gen II Pro also accepts many standard MIL-SPEC AR components—grips, two-piece handguards, and trigger upgrades—so customization options are broad. Whether you're introducing someone to rifle fundamentals, running a dedicated .22 practice rifle alongside your centerfire setup, or just looking for a platform that doesn't punish your wallet or ears, this rimfire AR delivers the form factor and reliability shooters expect.

The M4-22 Gen II Pro is ideal for shooters seeking low-recoil, low-cost practice; facilities that restrict centerfire ammo; youth and new-shooter training; high-volume plinking; or as a dedicated .22 trainer that mirrors centerfire AR handling and controls.
