Just tried them in My Stock WOC. goes in and out without any problems!
One thing, looks like the rubber thing that seal the nozzle with the mag is a bit too high, so if your bolt is not lock backwards, you need to slap them in.
The pull of the bolt is also hard the first few time you try.

and so far, the mag catch works flawlessly! A first for me lol.
