The Rock Island Armory M22 TCM is a bolt-action rifle chambered in .22 TCM. The 22.75-inch ordnance steel barrel with a 1:16 RH twist is designed for the cartridge's characteristics. One of the more practical features is magazine compatibility: the standard 5-round box is included, but the action also accepts high-capacity RIA .22 TCM pistol magazines up to 17 rounds.

Target Audience 

 
Shooters who already own or are interested in the .22 TCM ecosystem, particularly those with RIA .22 TCM pistols who want a rifle companion. Also suited for small-game hunters and competitive shooters who want a less-common caliber with light recoil. 
 

Usage Scenarios 

• Small Game Hunting: .22 TCM's velocity and energy are adequate for small game at reasonable distances. 
• Target Shooting: The adjustable trigger and long barrel support precision work. 
• Magazine Sharing: If you own a RIA .22 TCM pistol, magazines transfer between the two platforms.

M22 TCM owners tend to be enthusiasts who are already in the .22 TCM ecosystem, often because they own an RIA pistol in the same caliber. The magazine compatibility between the rifle and pistol is frequently highlighted as a practical benefit and a reason to buy.

Accuracy is well-regarded. Most owners report the 22.75-inch barrel and 1:16 twist deliver consistent groups for the caliber. The lack of iron sights draws occasional complaints since mounting an optic is a required first step, but most serious shooters see the receiver rail as the right starting point for a rifle like this.

Build quality gets positive comments on the whole. The Philippine wood stock is appreciated for its traditional look, and the steel receiver is considered solid. Minor feeding or ejection issues surface in a portion of owner reports, though these appear to be unit-to-unit rather than systemic.

Value is consistently rated positively relative to other bolt-action options. Price-to-performance discussion typically concludes that the M22 TCM delivers well for the cost, particularly for buyers who are leveraging the magazine sharing with an RIA pistol.
