The Definitive M16 Series: The SR-16 M4 Carbine
Developed by Knights Armament for US military special forces, the SR-16 M4 Carbine is a standout in the SR series of Stoner rifles. While the Knights M16 and SR-25 utilize 7.62mm x 51 bullets, the SR-16 uses 5.56mm x 45 bullets, making it comparable to Colt’s M4A1 carbine. Renowned for its meticulous craftsmanship and superior parts, the SR-16 M4 Carbine, also known as the "Black Knights" among elite special forces, is now available as an electric gun, faithfully replicating its real-world counterpart.
 
Key Features:
 
Metal RIS: The highly rigid die-cast aluminum RIS (Rail Interface System) features 20mm wide mounting rails on all four sides, complete with a vertical foregrip and handguard panel.
 
Authentic Knights' Lower Frame: The SR-16 M4 Carbine’s lower frame, distinct from Colt's, includes realistic details such as reinforced stock joints and the original Knights logo on a matte black finish.
 
Optical Device Compatibility: The top mounting rail on the upper frame allows for various optical devices compatible with a 20mm rail width.
 
Muzzle Customization: Removing the compensator enables the attachment of various muzzle options with a 14mm reverse thread, such as silencers.
 
Easy Hop Adjustment: Pulling the charging handle opens the port cover and retracts the dummy bolt, allowing quick hop-up adjustments via the dial-type hop-up dial.
 
Pressed Steel Magazine: The 68-round capacity magazine is designed to mimic the standard M16 magazine, although it is not compatible with next-generation electric guns.
