Choosing airsoft BBs starts with four details: the size your replica uses, the BB weight it supports, the type your field permits, and the cost for the quantity you need. Compare those details before comparing bag prices.
Shop all airsoft BBs, compare BLS .32g BBs, or view BLS .48g BBs for the exact products and current purchasing options.
BB diameter and weight are different measurements
The diameter describes the BB’s size; the weight describes its mass. A 6mm .32g BB and a 6mm .48g BB belong to the same nominal size category but have different weights. Check your replica’s manual for the required BB diameter and supported ammunition.
Choose weight using your replica manufacturer’s guidance and your field’s rules. The AEG, HPA or gas label alone does not tell you which weight to buy. If you already use a suitable weight successfully, compare replacement BBs at that same weight before considering other options.
Standard, biodegradable and tracer BBs
| Type | What to check | Shop |
|---|---|---|
| Standard / non-bio | Confirm that your field permits non-biodegradable BBs. Check the selected weight, color and package count. | BLS non-bio BBs |
| Biodegradable / bio | Choose a product explicitly labeled bio when your field requires it. Refer to that product’s documentation for material and disposal information. | Biodegradable BBs |
| Tracer | Match the BB’s tracer color to your tracer unit’s supported colors. Also check whether the specific BB is bio or non-bio. | Tracer BBs |
These descriptions are separate attributes: a tracer BB may also be biodegradable, but the word “tracer” does not establish that. Read the exact selected product description.
Tracer compatibility also varies by device. For example, ACETECH lists green-tracer support for its Bifrost and both green and red support for its Bifrost R. Check your own unit’s specifications before choosing a tracer color.
Comparing .32g and .48g BBs
.32g BBs and .48g BBs are different buying categories. Select a weight that suits your replica and field requirements, then compare like-for-like products within that category.
A bag of .48g non-bio BBs is not directly equivalent to a bag of .32g bio BBs. Differences in weight, material, color, count and tracer compatibility all matter. Use the selected variant’s specifications instead of a collection’s starting price.
How to compare the lowest price per BB
Cost per 1,000 BBs = selected package price ÷ listed BB count × 1,000.
This makes different package sizes easier to compare. For a multi-bag purchase, use the total item price and total listed BB count. If the package count is approximate, the calculated cost per 1,000 is approximate too.
A 1kg bag describes mass, not a fixed BB count. Use the count stated for the selected weight rather than assuming every 1kg bag contains the same number of BBs.
For the delivered cost, add applicable shipping and tax and subtract only discounts that apply to your order. Compare available products, check minimum quantities, and confirm the final checkout total. An advertised price for a sold-out variant is not an available purchasing option.
Before adding BBs to your cart
- Confirm the diameter and weight against your replica’s requirements.
- Match bio/non-bio and any tracer requirements to your field and equipment.
- Check the exact selected variant, package count and current availability.
- Compare cost per 1,000 and the delivered total for your intended quantity.
- Read the package’s storage instructions and retain its product information.
