Laylax shows you how to install the P90 Stealth Upper Receiver from their Proto Gear Arts brand released on a limited run. This lightweight upper receiver features a bold top cut similar to the popular XF50 Tri-Rail, offering optimal sight height and side rails for accessories. A magazine guide slider improves reloading, and the construction utilizes lightweight, rigid nylon resin.

In this video, Laylax shows how you can install the Proto Arts Gear Hot Rod Style M4 Upper Frame . According to the company, this ultra-light M4 upper frame simplifies your airsoft game experience! Integrating key parts and shaving 580g off a KRYTAC TRIDENT MK2 PDW-M, it streamlines handling and allows for quick hook grips. Its low-profile handguard even lets you mount flashlights closer to the barrel for precise indoor aiming. Plus, the versatile muzzle accommodates various attachments.

An interesting addon to the Krytac KRISS Vector is the Proto Arts Gear Strike Rail System 2.0 from Laylax which unfortunately will be sold exclusively in Japan. The “Vector Strike Rail System 2.0” is an evolution of the aggressive design of its predecessor, featuring an integrated knuckle guard with the “Advanced Grip” that spikes all front parts. Its large spikes, inspired by a crusher motif, and thicker side rails contribute to an unprecedented, overwhelmingly massive look.
