FNLite Means a Smaller & Lighter Bottle, with No Loss in Capacity

The Bunkerkings FNLite Carbon Fiber wrapped bottle line-up is engineered to be the lightest bottle you'll ever need. Simply screw your preferred 4500psi-rated HPA regulator on and get back to killing suckers. 

We've designed the the FNLite bottle to be up to 10% lighter and 9% shorter than the competition while still delivering the same number of shots with no loss in capacity? How do we do it? By using a proprietary DOT/ISO certified  carbon fiber wrapping technology around an aluminum liner, the FNLite shaves off weight and increases the inner volume at the same time.

With the FNLite, we've restored sanity to to bottle sizing that creates the perfect form factor and capacity for every player. Simply make your selection from four lightweight sized bottles: 60ci, 70ci, 80ci, or 90ci.

Super Low Quality/Unacceptable QC
Color: Black, Size: Wheel-6 Panel
I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.

Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.

Love it it was perfect for what I needed it for. Good quality!
Size: 4 Panel, Color: Black
It like a very dark chocolate brown/black. What I liked most about it is that you just pull it out of the box take the long plastic film off of it and it's ready to go. It has protective feet on the bottom. It's very attractive and it was so easy. It's so nice when you have a product you don't have to assemble.
