The grip is noted for its lightweight construction and durability, with installation demonstrated on an AR-15.

This guide explains the proper use of threadlocker on firearm accessories. It emphasizes using threadlocker on fasteners for items like optics and flashlights to prevent them from loosening due to recoil and vibration. The video recommends using blue Loctite for most applications, as it provides a secure hold while allowing for disassembly with basic tools. Red Loctite is noted as requiring heat for removal, and purple is suggested for very small screws.

This guide demonstrates a simple, effective method for managing accessory wires on an AR-15 platform without using zip ties or tape. The technique involves folding wires neatly into a dedicated pocket or channel on the accessory mount, then securing the mount.
