yes sir! haven't used it yet, wanted to see how it worked before i got more.Not too shaby. Are those thermold mags?
If you want polymer mags, I would suggest picking up some magpul PMags. They are the best mags on the market.
They are great mags. The only problem is they don't fit in XCR's and the FS2000. Maybe even others. Check that they work in your gun before buying a bunch of them.
