Submited By: Robert A. on 12/22/2012 Very impressed with my WE M4. I have about 2000 rounds through three of these mags. One was leaky when new, but stopped leaking when the seals got some silicone oil on them. Otherwise, I have not had any issues, other than screws and other threaded parts coming use, but that's pretty normal. Use threadlocker on screws and the nozzle if they come loose, and it should solve the problem. I ordered 6 more mags. | |
