### Detailed Features
The vent rib barrel disperses heat during sustained shooting and aids in maintaining a consistent sight picture. HiViz CompSight fiber optic sights provide fast target acquisition. The length of pull is adjustable from 13" to 14.25", which lets the gun fit a range of shooter sizes without adding a stock. The synthetic stock is weather-resistant and light.

### Usage Scenarios
The 9+1 capacity and fast cycling action make this a natural fit for 3-gun competition. It also works for hunting applications where a lighter 12-gauge with a shorter barrel is preferred. The adjustable LOP is particularly useful when multiple shooters share the gun.
