Here's a bit about Saiga rifles.
Saiga rifles are chambered for 7.62x39, 5.45x39 or .223Rem cartridges and intended for hunting, competition/entertainment shooting and self-defense.
Saiga series is based on the legendary Kalashnikov AK assault rifle. This design utilizes a proven gas piston system and two-lug rotary bolt, similar to Kalashnikov AK. Saiga rifles have the same ultimate reliability, simplicity of design and operation, which made the AK-series the most known firearm in history.
The barrel, chamber and gas piston are chrome-lined to resist corrosion and extend the life of the rifle. It also makes cleaning easier.
Receivers are made of stamped steel, furniture is made of heat and shock resistant polymer. Manual safety is identical to Kalashnikov AK, but it has only two positions - safe and semi-auto fire.
Optical and red-dot sights can be installed using special side mounts or Picatinny adapters, which can be attached to the side rail on the left side of the receiver.
