I've owned the M93R NS2 for about a year now and here's something i noticed amongst the 3 magazines I have. The first one I received had an initial leak which I fixed when I took apart the magazine and re-lubricated the seals. The other two work flawlessly; I have never had a leak from them and I can get about 1.5 - 2 mags worth of shots out if I fire in semi auto at a paced rate. However, the first mag, even after re-lubricating the seals, cannot fire an entire mag. I can maybe fire about 10 - 15 shots before the gas runs out. I have checked for leaks by listening for the leaks at the various valves and release ports and can't hear anything definite. Anyone have any ideas to why the other two mags function perfectly while the first one does not?
NOTE: The fill valve o-ring actually fell out of the first mag which I then replaced with a nitrile -002 BN70 o-ring. They were just a little bit tight fit to get in but comparing them to the o-rings in the fill valves of the other two mags they are approximately the same diameter and thickness.
