The Unicorn Airsoft brass inner barrel is a high-quality and extremely precise upgrade part designed to work with GBB platform airsoft guns.? The inner barrel is coated with Titaflon (a Teflon-like coating) reducing the friction from the BB as it travels.
This inner barrel's length is ideal for Hi-Capa, Night Warrior, M.E.U. and SIG AIR P320 M17 pistols.
