ID of Mags required

[hicky1300]

Hi All
Can you id these two magazines for me please? Weapon & caliber
Fairly sure the large one is for 20mm?
The Rifle one looks a bit complicated to me with the catch on the mag as opposed to the norm of the mag release being on the weapon
Must have made the mag expensive to make?
Thanks in advance
