Extreme Tolerance and Zero Jams:
G&G Armament BBs are globally considered the benchmark for precision in airsoft. Their manufacturing guarantees a flawless sphericity and a constant diameter, with a minimal production tolerance of only +/- 0.01 mm. This exceptional feature eliminates the risk of jams inside magazines and ensures perfect smoothness even in the tightest precision inner barrels (e.g. 6.01mm or 6.03mm), optimizing air seal in the hop-up unit.
The Balanced Weight (0.25g):
With its 0.25 grams, this BB is positioned at the point of maximum ballistic performance for the vast majority of replicas. It offers significantly superior wind stability compared to the classic 0.20g, sacrificing almost nothing in terms of muzzle velocity. It does not require extreme upgrades to be propelled efficiently: a well-adjusted hop-up unit is enough to obtain tight and precise groupings at medium distances, perfect for both woodland and urban engagements.
Competition Quality and Eco-Sustainability:
These BBs are made of 100% BIO material (PLA), a thermoplastic polymer derived from renewable sources that biodegrades naturally over time. Using G&G Bio Precision means not only being able to access all game fields and tournaments that require mandatory ecological BBs, but doing so by equipping your replica with a competition quality that in no way makes you regret the classic polluting plastics.
Main Advantages
Technical Specifications
The test bench for Mid-Cap magazines: Being perfectly smooth, G&G BBs are the perfect tool to test your Mid-Cap magazines. Very often, feeding gaps in bursts are the fault of cheap and rough BBs that get stuck in the feeding channel. If a magazine has feeding problems even when using G&G BBs, then you can be sure that the problem is mechanical (worn spring or internal dirt) and not the BBs!
Sworn enemies of humidity and heat: Being created precisely to degrade in the environment, BIO BBs fear extreme conditions. When you are not playing, make sure to always close the zip closure of the bag perfectly. Also, never throw away the silica gel sachet that G&G puts inside the package: it is used to absorb residual moisture! Also avoid leaving the bag on the car seat under the scorching sun: the PLA could expand and make you lose the magical tolerance of 0.01mm that you paid for!
