Detailed Features 

The inertia-driven action is mechanically simpler than gas-operated designs -- fewer parts mean less to clean and maintain. It cycles reliably with a range of standard loads. At 6.8 lbs the gun is light for a 20 gauge with a 26" barrel, which helps on all-day hunts. 
 
The Realtree Max-7 finish was developed specifically for waterfowl and marsh environments, with a color palette suited to cattails, timber, and open water. The synthetic stock handles wet conditions without warping. The 5+1 capacity gives you six shots before reloading.

The lightweight handling is frequently mentioned as a real-world advantage for carrying the gun through long hunts. The Realtree Max-7 camo is well-regarded for its look and effectiveness in waterfowl environments.
