4UANTUM Friction Pro: High-Performance GBB Buckings & Nub Set

If you demand the maximum range and laser-like accuracy from your gas blowback rifle, the 4UANTUM Friction Pro GBB Bucking is an absolute essential upgrade. It's a simple modification that makes a world of difference. 

Why Choose the 4UANTUM Friction Pro?

Top-tier Performance

The Friction Pro is precision-engineered to provide perfectly centred backspin on every shot. Whether you are building a high-speed CQB build or a long-range DMR, the Friction Pro ensures your BBs track straight and true. 

Consistency

RIF to RIF, the fitment and performance output of a bucking can vary. From overall customer satisfaction, the Friction Pro has proven to be the most consistent bucking for custom GBBR builds. Contact us for more information on which upgrades would best suit your gas-powered airsoft gun!

Highly Effective, Low Cost

An essential upgrade to your RIF - a high-performance bucking is simultaneously the cheapest type of upgrade, whilst also providing the biggest increase to your guns effective firing range, giving them an incredible bang-for-buck ratio. At only £8.95, 4UANTUM's Friction Pro is actually cheaper than some competing aftermarket buckings. 

In combination with an upgraded inner barrel, it's a small upgrade package that will give any standard gun a strong performance boost. Take a look at our range of high-performance AEG and GBBR inner barrels. 

Complete Hop-Up Solution

This set includes both the Friction Pro Bucking and a custom-matched tensioner (nub), ensuring optimal pressure distribution across the rubber.

Easy Fitment

Fitting a new hop-up bucking is relatively simple; it's a far cry from opening up a gearbox. But for those less tech-oriented and new to airsoft, we offer in-house tech services that will happily fit new bucking to your airsoft rifle.

Socom Tactical Pro Tip:

"When installing the 4UANTUM Friction Pro, ensure your inner barrel is completely degreased. A clean barrel combined with the high-friction surface of this bucking will significantly tighten your groupings at distances over 40 meters."

Is There Any Reason I Shouldn't Use a Friction Pro GBB Bucking?

Though the 4UANTUM Friction Pro may be the most all-round consistent bucking on the market, there remains a small set of cases where a Friction Pro would not be a suitable bucking:

• Low-quality Gas Pistols: most cheap GBB pistols lack return springs that are strong enough to contend with the heavy amounts of friction that this bucking generates, causing them to fail. 
• Maple Leaf hop-up chambers: Maple Leaf design their hop-up chambers specifically around their own bucking designs. Friction Pro's do not fit properly in these - best to use a Maple Leaf bucking instead. 

Key Features & Benefits

• Precision Centring: The unique internal geometry of the 4UANTUM bucking creates a stable contact patch, eliminating "flyers" and inconsistent horizontal spread.
• Enhanced Airtight Seal: Manufactured with high-grade silicone compounds, it provides a superior air seal against the nozzle, increasing FPS consistency.
• Universal AEG Compatibility: Designed to fit most standard Airsoft GBB inner barrels and hop-up chambers.

• Material: High-friction, wear-resistant elastomer.
• Compatibility: Standard GBB Inner Barrels (TM Spec).
• Recommended BB Weight: Optimised UP TO 0.48g BBs for maximum lift and stability.
