This is the exact same mag as the stock salvo mag. It looks great is made from hard durable plastic and has a lot of space for storage. It has a place for the 1/8 , 3/16 and 5/64 inch Allen keys. the clip that keeps it in the gun is tough and I have never had a problem with it, although it can make it a bit hard to remove one handed. The lock that keeps it together does a good job, but is a bit hard to grip with your nail. the clip is a bit flimsy side to side until it is clipped into the gun. It is a great magazine and if you lost yours, want it for your Alpha Black or are just wanting to mod you clip I would advise this clip.
