Trajectory Arms focuses on the components serious builders actually need. Their inventory includes:

• •Proprietary melonite gas tubes (carbine, midlength, rifle lengths with roll pins)
• •Gunsmithing services including pin-and-weld muzzle device work
• •Specialized hardware: gas block set screws, roll pins, coiled spring pins
• •Armorer tools: Loctite threadlocker, armorer chem kits with refills
• •Tactical accessories: NAS switches for MP5 and MP5-K, VUDU LPVO swing levers

• •What sets them apart: They manufacture their own gas tubes rather than reselling commodity parts. Their armorer chem kits and specialized hardware appeal to builders doing serious work, not casual shoppers. The NAS normalized activation switches indicate they cater to precision-minded customers working with quality platforms.
