Available in 9mm, .223, and 300 BLK, the new X-15 SCU (Side Charging Upper) from X-Products is designed to improve ergonomics and allow the shooter to keep eyes on the target. The left-side charging handle is non-reciprocating and is designed to not interfere with standard controls and accessories.

The billet machined aluminum is Cerakoted and available in black or flat dark earth. It is a drop-in upper and works with MIL-STD bolts without requiring modification.

The right side of the X-15 SCU mounts a small rail where the forward assist is usually located. This can be used for close-in back-up sights with the rifle rotated 90 degrees.
