Thisconverts the M4into a .50 Caliber battle rifle, substantially increasing its damage at the cost of fire rate and recoil control. The weapon’s visual recoil and gun smoke are adjusted to MW3 standards while this attachment is equipped, so the kit is surprisingly easy to use once you get used to the recoil.
In terms of stats,it’s an objectively better Sidewinder.It deals 101 damage per shot and fires at 245 RPM, allowing it to kill someone in two quick shots. The kit also reduces your handling and mobility stats.
This kit locks your magazine, ammo, and muzzle options.
