YES! Awesome. A shroud is so much better than a bottle cap opener tool on the mag catch.
Makes me want to get UBB Tools to install on my mags now. I like how using a UBB on a mag with the AK BB shroud style is so much faster and easier than with an AR-15 BB.
Or like the Solar Tactical Tool in this video.

Probably won't be able to reload quite as smoothly as with an AK with Bullet Button, but it should be better than using a bottle cap opener tool.
Looking forward to seeing details on the Prince 50 Tavor Bullet Button. Thanks.
