Indeed
I have those very same mags but be careful when filing them down cause if you go a little to far with the file when you push the mag into the gun it will go up a little to far, so when you go to load the bullet when pushing the bolt forward it will catch the bullet at the receiver ..simple fix is when you load the mag pull down on it as if to try and pull the mag back out of the gun without releasing the clip - dont pull hard its only a few millimetres depending on how much you are off that you pull it down....
I have been using mine for about a year now and they are excellent value for money..they cost 10 dollars a pop though when i bought em...then delivery...
hope this helps...
