"Ok so people will tell you not to use this or that just because of they're experience and I've been told that kjw mags are bad all together but I own plenty of kjw guns and used there mags and have had no problems with them no leaks so if you keep the orings lubed they should be just fine they have work perfectly fine

"I own 4 of these magazines. Only 1 held gas. The rest, even in their brand new condition, leaked straight out of the box.

When they hold gas, they work brilliantly, and do feel of good quality construction i've come to expect from KJW

Im always dubious when buying these mags, and often wait till they're marked down in price, due to the high chance of leaking.
