Mines great, I would get the adjustable reg so you can rotate the fill nipple to where it won't dig into your wrist.

Positive Feedback

Tank regulators have very, very little affect on modern markers consistency.

Core Power Plays

The specs and strengths that make it shine.
Discussion about tank weight and materials
what is the lighests tanks no hk army
Lightest non hk is probably an infamous tank
Anything carbon fiber is going to be light with the heaviest spots being the first and second stage regulator.
I run a 90/4500 carbon fiber ninja and personally feels lighter than a aluminum 48/3000
Discussion about tank sizes
Hk army alpha air Was not prepared for the actual size of this tank in person!
I’ve really been wanting to pick one up.
Discussion about the importance of regulators for consistency
So despite common misconceptions, your accuracy in your marker starts with the regulators.
Mention of Ninja's involvement in manufacturing regulators
It’s changed over the years. I know ninja made their aerolite 2 reg. It has the ninja logo on it.
Discussion about tank manufacturers
I think manufacturer that makes HK tanks do the Infamous tanks as well (someone please fact check me).
Discussion about air tank thread sizes being standard
Question about air tanks for beginners So I just bought a Tippmann Cronus paintball gun.
All paintball tanks use ASA threads. ASA stands for Air Source Adapter.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Brand perception as a lifestyle choice rather than quality
like all lifestyle brands, they are coasting on their early day vibes and selling mostly poorly made products with designs that are particularly appealing to teenagers and people who unironically use the word “agg”.
Marketed towards beginners but may not meet expectations
They definitely market themselves as being a good brand for beginners and I bought into that marketing, only listening to direct opinions from people I play with from now on
Comparison of tank sizes creates discussion
Big weight difference? I use an infamous 80 right now.
General consideration of the relationship between tank cost and performance
Get whatever is on sale in the size you need.
Discussion about thread sizes for paintball tanks
I am an air gunner who is looking to use paintball tank for my pcp project.
All paintball tanks use the same threads, 1/2" NPS - it's the only thing in paintball that has actually become an accepted universal standard.
The tanks themselves use 5/8"-18UNF normally to attach the regs.
it is a CGA-320 thread. 0.825"-14NGO-RH and standard for compressed CO2.
Discussion about buying used tanks as a cost-effective alternative
Buy a used tank. Jump one the Facebook BST pages, or /r/paintballbst and get a tank.
General chatter about tank longevity and maintenance
Only need to hydro vs throw out after 15 years.
General opinions on tank performance and pricing
The HK Aerolite is perfectly adequate for most casual players' purposes.
Debate on tank sizes and necessity for upgrades
A 68 cubic inch, 4500 psi tank has been very common for many years, you can go bigger, but it's probably unnecessary as you can refill the air tank after each game at most fields.
General inquiry about tank refilling methods
Can I refill my air tank with my air compressor

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Debate around tank manufacturers and quality perception
Opinion on HK tanks. Debating on trying an hk tank.
HK Army Tanks? Hey all, does anyone know anything about the HK Army Aerolite Extra Lite?
A carbon fiber (wrapped) bottle is a simple thing. They're all the same quality because they're all regulated by the Department of Transportation.
HPA Tanks and regulators What are some good HPA tanks? I’ve been looking at the first strike tanks with the Basic HK Army Reg.
Discussion about tank quality perception and alternatives
Alpha Air 77/4500 Absolutely terrible timing for this, given recent events, but these tanks are legitimately a game-changer.
Still a solid tank. Now might have to change the name from Alpha Air to Tiger Tank.
Coming up next, the 88ci tank, HK's final solution for big games.
