Competitive shooter Clyde Santos takes a very good look at the 4UANTUM Magnus Pro 2011 hop-up chamber, a piece of airsoft hardware designed for those who enjoy spending quality time with their tools. Clyde notes that while the packaging is neat and professional, the real magic lies in its adjustability. It is designed with a bit of "wiggle room" to ensure it fits a wide variety of pistol brands, which can then be tightened down for a solid fit.

Toronto Airsoft introduces a variety of airsoft products from 4UANTUM Industries they have available, including a custom trigger for Glock series pistols, a Magnus Pro Gas Blowback Hop-Up Unit for VFC and GHK gas guns, and Friction Pro Hop-Up Buckings for AEGs and gas guns.
