XYL Unicorn Yamaha Upgrade Kit

XYL Unicorn Modded Parts Introduction：

Use our XYL Unicorn upgrade parts and mods to boost muzzle power and durability — upgrade your XYL Unicorn nerf gun.

Specifications:

• Nozzle: After the update, retracting the nozzle no longer creates negative back‑pressure; the stock nozzle requires more force to retract. An added O‑ring improves the air seal. Compared with the stock nozzle, this upgraded part delivers greater and better airflow. Before installation, apply a sealing lubricant to the O‑ring to enhance airtightness.
• Cylinder: To prevent wobble, dab adhesive around the outside of the cylinder to fix its position and improve the seal.
• Buttstock extender base cap: Threaded—allows installation of an extended stock core.
• Breath-Groove Piston：Upgrade to a breathing-rib piston for better air seal and smoother movement
• 20cm Inner barrel: universal inner barrel with a standard outer diameter of 16 mm and inner diameter of 13 mm. Considering this blaster’s effective air volume, if you fit your own inner barrel, do not exceed 35 cm in length.
• Extended rail
