Specification

Heavy-hitting precision ammo

These BLS Supreme Grade 0.40g BBs are built for high-power sniper and DMR replicas where every shot counts. The substantial weight resists wind and holds a stable line for confident long-range hits.

Consistency you can rely on

Held to a 5.95mm diameter with +/- 0.01mm tolerance, each round is uniform. That precision is what lets a well-tuned hop-up deliver the tight, repeatable groups marksman players demand.

Smooth feeding, clean flight

A seamless, high-polish surface keeps these heavy BBs feeding cleanly through hop unit and barrel without scoring. The bright white finish makes loading magazines simple.

Match your platform

Best paired with higher-power replicas that can lift the extra weight through a well-tuned hop-up, delivering the flat, stable flight these heavy BBs are known for. Find compatible gas, batteries and more in our BBs, gas and batteries range, or browse our full airsoft line-up.

Frequently asked questions

What are 0.40g BBs used for?

0.40g BBs are aimed at high-power DMR and bolt-action sniper replicas. The heavy weight gives excellent wind resistance and a stable, flat trajectory for long-range accuracy.

How many BBs are in the bag?

This is a 1000-round bag of 0.40g BBs. The bag is resealable, so any leftover ammo stays clean and dry between outings.

Can I use these in a standard AEG?

You can, but 0.40g BBs are best matched to higher-power replicas. In a low-power AEG the hop-up may struggle to lift them, reducing range and accuracy.

Why are these sold in smaller quantities?

Heavier BBs are typically fired in lower volumes by precision shooters, so a 1000-round bag suits sniper and DMR players who prioritise accuracy over rate of fire.

What quality standard are these?

These are BLS Supreme Grade precision BBs, measured at 5.95mm with +/- 0.01mm tolerance and a seamless polished finish for consistent, reliable performance.
