Specification :

RAP4 Airfin for RAP4 Generation 2 Airsoft guns. The RAP4 Airfin is the first BB that is aerodynamically designed for long-range targets.

The RAP4 Airfin is 6mm in diameter, 11mm long and weighs .19 grams. Designed for Airsoft gaming, it gives players better accuracy and increased distance to engage opponents while you're safely out of their range!

Each RAP4 Airfin is loaded in a shell casing to feed into the RAP4 from the 20 round detachable magazine; the shell casing ejects out of the gun just like a real M4!

RAP4 Airfin BBs are designed for long-range shooting. Four fins stabilize each BB in flight, just like a torpedo, so they glide through the air for the maximum distant possible. The head of the RAP4 Airfin is oval to reduce wind resistance for increased accuracy.

RAP4 Airfin is the first of its kind, and gives Airsoft players the edge for wining battles! These fin-stabilized BBs take Airsoft to a new level of realism: realistic magazine capacity, shell casing ejection after each shot, and extreme accuracy.

RAP4 Airfin will change how Airsoft games are played, and take your sport to the next level of fun, realism, and excitement.
