AK Gelblaster Electropolished 7.5mm Stainless Barrels

Hi Everyone,

Along with a couple of new hop ups from AK GB a 450mm stainless steel electropolished barrel arrived, thought I’d share a few details as I was fairly impressed. Not advocating for SS barrels being better in any way as modding blasters is still pretty new to me but hopefully this might be of interest to some people.

At first I thought Electropolishing was marketing jargon talk but apparently its a thing, whether that’s the process these barrels actually undergo is another matter, but they’re certainly shiny.

When initially looking down the bore I was pretty disappointed as it was incredibly dull, the inside of the barrel was incredibly dirty, assuming that’s from the electropolishing process. After about 20 minutes with a 7.62mm nylon brush, isopropyl alcohol and several patches the bore really started to shine.

Close up photography is not my forte so I wasn’t able to get a photo of how polished the bore is, but I was able to put a light down one end and the phone camera pressed up against the other to show just how much light is reflected inside the bore, hopefully that gives some indication of how polished it is.

Patches before and after

It also has a really nice bevel on each end

45cm is too long for my needs but I bought it with the intention to cut it down to make a 28cm and a 15cm barrel but given show shiny it is I’m thinking of trying a 33cm barrel on an SLR ION with a full cylinder.

I’m not expecting miracles out of this thing but looking forward to the experiment to see how it performs (or doesn’t)

I think the main benefit to stainless barrels was their rigidity, being a harder metal than aluminum, they won’t wobble/flex as much when shooting.

You will need a proper cutting disk or a hacksaw to get through it though obviously, and I had to use a pointed grinding bit to clean up and bevel the edge.
