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.
