Opinion on HK tanks. Debating on trying an hk tank. I HEARD (key word heard so idk) they’re made by the same manufacturer as ninja? Could be wrong but idk just want some input.

Positive Feedback

I fully understand that HK does not manufacture their own guns, but my problem all along was that they sent me pictures and videos showing me that they had worked on, and fixed my mini, then 2 weeks later when I finally got it back it had the exact same problem as when I sent it in.

What it does well!

Key strengths users can’t stop talking about.
Lightweight design for ease of use
“Opinion on HK tanks. Debating on trying an hk tank. I HEARD (key word heard so idk) they’re made by the same manufacturer as ninja? Could be wrong but idk just want some input.”➕
“Their basic regs are fine, people are just elitists when it comes to regs when it really doesn't make that much of a difference. Their pro style regs are manufactured by Ninja, so they're fine as well. I run an HK 80ci tank with an Immortal Air Ascent reg personally.”➕
“Mines great, I would get the adjustable reg so you can rotate the fill nipple to where it won't dig into your wrist.”➕
“I have a 77 and love it. It’s roughly the same size as a regular 68.”➕
Reliable performance with consistent output pressure
“Went from 48/3000 metal boi to 68/4500 aerolite with absolutely zero regrets.”➕
Satisfactory performance with no major issues
“Yeah. Nothing special, but by no means bad.”➕
Aesthetic appeal of the tank design
“The doom tanks are beautiful 😍”➕

Poor product quality control
“I fully understand that HK does not manufacture their own guns, but my problem all along was that they sent me pictures and videos showing me that they had worked on, and fixed my mini, then 2 weeks later when I finally got it back it had the exact same problem as when I sent it in.”➕
“Their elbow pads give me carpal tunnel, xl kneepads were way too small on certain parts, and the reg busted a pin valve seal and I can’t find an easy replacement.”➕
Concerns about regulator quality
“HK's regs are OK at best. In the $180+ price range, it's money best spent getting something with a solid reg.”➕
Concerns about the quality of regulators
“The reg is the important part. I don’t trust their regulators as they are just the large scale Chinese crap.”➕
