The KWA M4A1 RIS LM4 PTR Gas Blowback GBBR Full Metal Airsoft Rifle in this complete gas and BB bundle delivers a highly realistic platform built for serious airsoft players and training applications. Powered by KWA’s Force Velocity gas system, this rifle features a reciprocating bolt that produces strong recoil and consistent cycling, closely replicating real M4 operation. Constructed with a full metal receiver, barrel, and buffer tube, the LM4 PTR offers a solid, durable build that performs reliably under demanding conditions. Shooting at 400–440 FPS and capable of 13+ rounds per second, this gas blowback airsoft rifle provides both power and speed for outdoor engagements. The adjustable hop-up system allows precise tuning for improved accuracy and extended range beyond 100 feet, while the 40 round magazine supports sustained gameplay. A 14.5 inch barrel, A2 front and rear sights, and full Picatinny rail system provide flexibility for mounting optics and tactical accessories to suit any loadout.
The Lancer Tactical 0.25g Streamline competition grade BBs are engineered for smooth feeding, tight grouping, and minimal jamming, ensuring dependable accuracy across extended sessions. Paired with Lancer Tactical 12KG high PSI green gas infused with silicone, the rifle benefits from enhanced power output while maintaining lubrication of seals and internal components for long-term durability. The retractable crane stock with sling loop and QD attachment, along with front sling mounting options, allows for versatile carry configurations across different playstyles. With semi and full auto firing modes, realistic field stripping, and robust construction, the KWA LM4 PTR stands out as a premium gas blowback airsoft rifle that combines authenticity, performance, and reliability in a complete, field-ready bundle.
