The RCM Shuttle Mechanical Mod is a new Semi-hybrid mechanical mod made of brass. The Russian Custom Mods Laboratory produces many years of weapon fittings, so the materials used are distinguished for their high quality.
Brass is characterized by high resistance to high temperatures, impacts and pressures. Mod colors and ways of dyeing are highly specialized and at high cost. All of this makes it one of the best mechanical mods in the world market.
