Description
The GBBR M603 M16A1 COLT CGS CYMA Replica, a long gas replica in the classic M16A1 format
The GBBR M603 M16A1 COLT CGS CYMA Replica is a gas-operated airsoft replica inspired by the M603 M16A1 format, designed for players looking for a historically-styled long platform with Gas Blowback operation. It features a 20" external barrel, M16A1-style fixed stock, licensed COLT markings and full metal receiver, reinforcing its visual identity and realism when handled.
This replica combines several materials, with aluminum, zinc alloy and fiber-reinforced polymer construction. The full metal receiver provides a rigid base, while the M16A1-type fixed stock retains the ergonomics characteristic of this long format. Internal components are also in steel, notably the bolt carrier with aluminum buffer set. The barrel and gasket are GBB standard. These design choices give the replica a more realistic orientation, consistent with its GBBR operation.
Gas Blowback operation reproduces a firing cycle with perceptible mechanical movement with each shot. Feeding is by gas, with a 20-shot gas magazine supplied in the box. The replica features semi-auto, full-auto and safety firing modes, enabling its use to be adapted to the rules of play and the situation. The adjustable hop-up allows you to adjust the ball's behavior, while the quick-release hop-up chamber facilitates access to the adjustment. The GBBR M603 M16A1 COLT CGS CYMA replica stands out for its long 980 mm format, 20" outer barrel and fixed-stock M16A1 configuration. It comes with a replica and a 20-bbs gas magazine.
