What a beautiful high quality set of Magazines, I treated them with a nice quick squirt of silicon and add the BB's and they work perfect!

Well Worth the money.

"Using these in our Krytacs and seem to work well. Did have to run a few fills through them to break in. If I need more mags these are the ones I will buy again. A few misfires when cold but I would expect that from any brand. As with anything keep them clean and they work fine.
