HK Army
An HPA tank is smooth aluminum, and once it's cold, sweaty, or you're gripping it with gloves, it slides out of your hand without a lot of warning. The Tank Grip 2.0 is HK Army's fix for that.
What it does. It's a pre-shaped rubber sleeve that wraps your tank and gives you an actual place to grab it. The rubber also cushions the hard metal against your vest in close quarters and adds a thin layer of impact protection for the aluminum body underneath. The Black & Blue colorway is straightforward styling on an otherwise functional part.
It fits everything. One grip covers the entire HK Army tank lineup: 48ci through 100ci. The stretch rubber conforms to each size, so you don't need to track down a different grip when you swap to a larger tank. Installation is literally just pulling it on.
What it's not. This is a comfort and handling upgrade, not a mounting system. It doesn't replace your tank sling or harness. It also only fits HK Army tanks — if you're running a different brand's aluminum cylinder, the dimensions won't line up.
