History of M4 Rifle, the Real World Predecessor.
The M4 is a compact automatic rifle developed in the United States based on the popular M16 assault rifle, with a focus on the need for a lighter and shorter version suitable for urban combat.
In the 1960s, the M16 rifle, developed by Armalite for the U.S. military, served as the base design for the future M4 rifle.
In the 1980s, the first M4 prototypes appeared, featuring a shorter barrel and telescopic stock, improving the rifle's maneuverability in confined spaces.
In the 1990s, the M4 was officially adopted by the U.S. armed forces as the standard assault carbine, replacing older models like the M3 and M9.
The M4 rifle is characterized by its ability to fire single shots and bursts.
It quickly became popular among soldiers due to its lightweight, compactness, and reliability.
It was widely used in conflicts in Iraq and Afghanistan and became an iconic weapon of the modern U.S. military.
Besides the standard model, many M4 variants exist, equipped with different accessories and upgrades to meet the specific needs of military units.
This modernized AEG rifle, the M4 CQB M-LOK RRA SA-P17, in the top tier Prime™ series from Specna Arms, boasts excellent body craftsmanship and is equipped with a M-LOK handguard that offers a more secure mounting system on the weapon while being easier to grip.
Specna Arms Prime™ is the top tier.
It represents the best, most refined, most upgraded, most perfect, and most reliable that Specna Arms has to offer.
Shortly said, Specna Arms decided to take the perfectly fitted body from the Edge 2.0 series with Nano Coating surface treatment, which boasts increased resistance to scratches and damage, and load it with high performance upgrade parts.
They started with the motor upgrade, specifically a brushless motor housed in a new QD grip for quick access to the motor.
The replica also features a completely redesigned ÆTHER gearbox, capable of handling AEG springs up to M140.
Inside, you'll find a Bluetooth ASTER II ETU processor unit, CNC gears with a 16:1 ratio,
CNC cylinder and piston heads with CNC nozzle, 8mm ball bearings on the piston and motor gears, and a slide bearing on the sector gear.
Accuracy is ensured by a 6.02mm inner barrel, fitted with a Helium Flat hop up bucking in the redesigned MAGNUS™ hop-up chamber with TDC pressure system.
In less than a minute, thanks to the ESA2 quick spring change system, you can install diferent spring.
