This modification replaces the firing of shotgun pellets with rifle rounds. It’s important to note that this conversion results in a decrease in handling and recoil control.

The following attachments are selected to mitigate the drawbacks highlighted above to ensure that shots land on targets even with sustained fire.

Starting off the build is the ZEHMN35 Compensated Flash Hider, which is an excellent muzzle attachment for both vertical and horizontal stability, firing aim stability, and reducing radar ping duration.

Next, for underbarrel, the Bruen Heavy Support Grip further enhances recoil control, ensuring that follow-up shots remain accurate.

For lasers, the 1MW Quick Fire Laser is used to increase aim-down-sight speed, helping to counterbalance some of the negative effects of the previous attachments.

Lastly, the popular JAK Glassless Optic provides a slight boost in firing aim stability, completing the weapon build.
