Subject: RE: PMAG Question (Long-Term Storage)
Thank you for your inquiry. The factor that truly wears out quality springs is compression cycles, not constant compression. However, we use a high-quality stainless steel springs in our PMAGs and if one ever does happen to wear out any USGI spec spring can be swapped out for the factory one.
Regarding the question of how long, we’ve had magazines fully loaded for over four years now with no Impact/Dust Cover on and have experienced no feed lip or spring issues. With the cover installed storage life is considered indefinite. There have also been PMAGS reportedly tested to hundreds-of-thousands of rounds (military vetting), and we know positively of ones that have gone tens-of-thousands, so usable life is quite excellent too.
