M4 & AR-15 Variant Airsoft Assault Rifles

If you're in search of an affordable, easy to master and fully upgradable primary, the NUPROL Delta Pioneer Recon M4/AR-15 AEG should be in your sights! This M4/AR-15 AEG replica is constructed predominantly from high density polymer and equipped with plenty of attachment interfaces, from its 20mm Picatinny railed receiver to its mock KeyMod handguard with pre-installed rails and 14mm CCW male threaded barrel. Whether you want to rock a red dot sight, rifle scope, tracer unit, suppressor, vertical grip or bipod, the M4/AR-15 Recon is ready!

Though it may be mostly polymer, this isn't the usual shiny "super-soaker" tier stuff; this is nylon fibre-reinforced polymer, the kind that may well outlast alloy when it comes to endurance. Inside, we are equipped with an alloy version 2 gearbox with 18:1 ratio steel gears running on 8mm ball bearing bushings and driven by a 21K RPM high torque motor; a competitive feature set for a platform at this price!

The inner barrel is also a 6.03mm tightbore paired with a 50° HOP-up bucking and rotary HOP-up unit, ensuring you can reach out and engage at longer ranges with an accuracy advantage using high quality BBs. If you need a cheap and cheerful beginner platform with plenty of upgrade and customisation options or a reliable, lightweight back-up platform to loan to mates or use when your arms get tired, the NUPROL Delta Pioneer Recon M4/AR-15 AEG is a fantastic option!
