KILO9 is a line of airsoft BBs produced and distributed by ASG — Action Sport Games — one of the world's largest manufacturers and distributors of airsoft equipment. ASG, headquartered in Denmark, has been supplying airsoft players worldwide for years, and the KILO9 line represents their precision ammunition offering: BBs for AEG, GBB, and spring-powered replicas, available in both standard and biodegradable variants. The KILO9 name draws directly from military terminology — KILO is the phonetic equivalent of the letter K (from "kill"), and 9 refers to the 9 mm caliber, a symbol of effective combat ammunition.
Manufacturer and Market Position
ASG (Action Sport Games) is a Danish airsoft manufacturer and distributor, founded in 2003 and headquartered in Copenhagen. The company has grown into one of Europe's largest airsoft distributors, offering both proprietary-brand replicas (Bersa, Beretta, CZ, H&K under license) as well as accessories, tactical apparel, and ammunition. KILO9 BBs are a line tailored to the demands of today's MilSim players and airsoft competitors who expect precision, consistency, and minimal environmental impact from their ammunition. ASG KILO9 BBs are manufactured to strict diameter tolerance standards, resulting in consistent hop-up engagement and predictable ballistics on every shot.
Specifications and Available Weights
ASG KILO9 BBs are available in several weights and variants, suited to different replica types and playing conditions. The 0.20 g weight (5000 rds / 1 kg) is the lightest and fastest option, designed for low-powered replicas and CQB indoor play where reaction speed matters more than range. The 0.23 g weight (4350 rds) is a versatile middle-ground for both outdoor and indoor players, offering better energy retention than 0.20 g while maintaining acceptable muzzle velocity. The 0.25 g weight (4000 rds) is the go-to choice for mid-range players running replicas in the 350–400 FPS bracket, and is especially popular on outdoor fields. The 0.28 g weight (3570 rds) is a heavyweight option for high-performance replicas exceeding 400 FPS, delivering maximum flight stability and wind resistance during field play. The Biodegradable (BIO) series is available in 0.20 g, 0.23 g, and 0.25 g — biodegradable BBs break down naturally in the environment, which is especially important for games played in woodland and environmentally protected areas.
Quality and Precision
ASG KILO9 BBs are manufactured with tight dimensional tolerances — the critical factor determining reliable feeding from the hop-up chamber, jam-free magazine performance, and repeatable ballistics. The standard diameter is 6 mm ±0.01 mm, placing them in the same tolerance class as premium BBs from other top manufacturers. The smooth, seamless surface of KILO9 BBs reduces the risk of scratching the hop-up chamber and bucking. BBs are packaged in 1 kg bags for easy round counting and compatibility with a wide range of loading systems, including speed loaders and box mags.
