Detailed Features 

The matte black steel barrel pairs cleanly with the walnut stock. The Active-Choke system includes five chokes (Full, Improved Modified, Modified, Improved Cylinder, Cylinder), giving the shooter real flexibility to adapt to different ranges and game. The crossbolt safety is positive and fast to engage. The fixed walnut stock has a straightforward ergonomic profile that suits right-handed shooters well. 
 
At 7.50 lbs., this is a moderate-weight shotgun. The semi-auto action manages recoil reasonably well across standard 12-gauge field loads.

Users of the CZ 712 G3 Walnut generally appreciate the wood-and-matte combination and the semi-auto cycling. The walnut stock draws compliments for its appearance and the solid feel it gives the gun in hand.

The semi-auto action is frequently called smooth and reliable across varied loads. The five included chokes get credit for making the gun adaptable for both clay sports and hunting.

Weight is the most common criticism. At 7.50 lbs., some shooters find it heavy for all-day field use, particularly compared to lighter over/under or pump options. A few mention that balance could be improved.

Overall the 712 G3 Walnut is well-regarded for its combination of classic aesthetics and reliable semi-auto function.
