Help identifying some gear/accessories

[PeyotZET]

I can describe a couple of accessories that I'm somewhat interested in, but I do not know their names. Can anyone help me?

1) U-shaped accessory that attaches to your vest. If your gun is on a sling it's supposed to catch the front handguard and lock it in place, so it functions almost as a holster.
2) Another vest accessory that holds your mags in a plastic shell, similar to a magwell. You pull your mags down and out of it in order to reload.

I am also wondering what hydration carrier/bladder is the favorite among airsofters, and why.

1.) Weapon catch, phantom makes one
2.) I think your talking about a fastmag
3.) I like hyrdastorm's carrier and I use BLACKHAWK speed clips to secure it
