Fusil Colt M4A1 Short Keymod AEG

I am selling this brand new COLT M4A1 SHORT KEYMOD FULL METAL AEG CYBERGUN replica rifle. I have never used it. I bought it 2-3 years ago to start airsoft, but it didn't happen. It comes with its charger, battery, silencer, ergonomic grip, and an RTI Optics holographic sight (which doesn't light up for some reason, so I'm not including it in the price).

Features :
- one-piece metal barrel guide
- One-piece upper and lower aluminum chassis
- Metal gears and mechanism housing
- Keymod machined handguard
- 3 Picatinny standard rails
- 350-round metal magazine
- Adjustable BAXS firing system
- Adjustable stock adaptable to all sizes
- NiMH battery and charger included
