A MEC Spring may be small, but for reloading, it is just as important as the larger and more expensive items used. MEC began in 1972, when the first coiling machine was launched. Since that time, over 30 different spring machines have been manufactured, as well as replacement parts, like this spring. In addition to multi-axis spring formers, coiling machines for extra fine wire, spring formers, torsion spring machines, and extension spring machines, the company now has over 5,000 machines throughout the world. For people who do reloading on a MEC spring machine, this replacement part is imperative.
