Octarms 16 Tan from Amoeba range with Keymod CNC handguard proposed by !


The Hong Kong manufacturer has created a replica based on an AR-15 model, available in several handguard sizes: here, it is the 16 model.

With its Amoeba range, offers reliable but affordable airsoft replicas with a very good quality/price ratio! This polymer replica is nice and easy to handle and very durable.

Internally designed, the M4 Octarms embeds a programmable mosfet directly into the gearbox.

Add to that a high-torque motor and a full metal piston for a very respectable performance;
