G&G BIO BBs, 0.33 g, 5600 pcs, Grey

G&G BIO 0.33 g are grey, biodegradable 6 mm airsoft BBs in a tub of 5600. The weight is heavy and aimed at upgraded AEGs, DMRs and HPA guns, where you want a stable trajectory at long range.

At high muzzle velocity, light BBs become sensitive to wind and over-rotation from the hop-up. A heavier BB holds its energy longer and flies more predictably, but also needs a gun with enough power for the hop-up to lift it. As a rule of thumb, 0.32–0.33 g suits guns from around 115 m/s and up, measured with 0.20 g. For most stock AEGs, a lighter BB such as Hank Tactical BIO 0.28 g is a better choice.

G&G BIO 0.33 g – what you get

What you need to know about these BBs:

• Tolerance 0.005 mm: G&G states a size tolerance of 0.005 mm, where many BBs are at 0.01 mm. The more uniform the BBs, the more consistently they seal in the inner barrel and hop-up bucking.
• 0.33 g weight: Heavy enough to hold a stable trajectory in wind and at long range. In a low-velocity gun, on the other hand, the BB will drop early.
• BIO: The BBs are biodegradable, so they can be used on the many outdoor sites that require BIO BBs.
• Grey colour: Grey BBs are harder for opponents to trace back to you than white ones. On the other hand, they are also harder for you to see when setting your hop-up.
• 5600 pcs per tub: The tub is resealable and lasts for many game days with a DMR or HPA gun.

Maintenance and safety

• BIO BBs can absorb moisture. Keep the tub closed and dry, and use the BBs within a reasonable time.
• Adjust the hop-up when you switch to 0.33 g, so the BB neither drops nor rises too much.
• Never use BBs that have been on the ground – dirt can damage the inner barrel and hop-up bucking.
• Always wear approved eye and face protection.
