DAA 13-Coil 2011 Mag Spring by Double Alpha Academy
The 13-Coil (170mm mags) DAA 2011 magazine springs are made from hi-quality spring wire, and carefully formed and manufactured to maximize reliability, capacity and longevity.
The coils are designed to collapse upon one-another, to allow the spring to compress shorter. The upper coils have a more elevated angle, to prevent “nose-dives” and improve feeding performance.
These springs can be used in all 2011 style magazines, in all calibers.
