XM177 Assault Rifle and Its Successors

XM177 is a weapon developed in the United States during the Vietnam War as a compact version of the M16 assault rifle. Officially known as Colt Model 610 and Model 629, XM177 was designed by Colt in the 1960s. The main goal was to create a lighter and shorter variant for special operations and units that needed greater mobility in jungle and urban areas.
XM177 used the 5.56x45mm NATO cartridge and had several key features that distinguished it from the standard M16. The barrel length was shortened to 10 inches in the Model 610 and 11.5 inches in the Model 629, making it a much more compact weapon. Due to the shorter barrel and reduced weight, which was approximately 2.6 kg, XM177 became popular among soldiers who needed a lighter and more maneuverable weapon. The firing system was a gas-operated rotating bolt, similar to the M16.
The development of the XM177 had a significant impact on the later development of assault rifles, particularly the iconic M4. The M4, which began to be used in the 1990s, incorporates many design elements and concepts that were first tested on the XM177. The shorter barrel, telescopic stock, and overall compactness of the M4 are directly inspired by the XM177, demonstrating the long-term influence of this weapon on the modern military arsenal.

What Does the WE GBBR Gas Rifle XM177 Offer?

With the GBBR rifle WE XM177, you will experience an authentic shooting feeling that provides a more realistic and engaging shooting experience.
The replica was manufactured as accurately as possible according to the real model, and inside you will find fine-tuned internal parts for excellent performance and reliability without the need for immediate investment in upgrade parts.
Control elements mimic their real counterparts as closely as possible, making it perfect for practice handling the weapon or tactical exercises.
GBBR gas rifles from WE boast excellent ergonomics and offer shooters a real experience.
All external parts are well-made for comfortable and intuitive control, prepared for intensive use in games, training, or sports shooting.
Therefore, gas guns from WE can rightfully be considered among the most widespread and popular among beginners, garden recreational shooters, and advanced hardcore players who customize their replicas to perfection and modify their rifles according to real service weapons.
WE GBBR with a metal moving bolt
 are suitable for medium-power gases. We recommend using gases such as Green Gas or Red Gas in colder weather.
Besides a realistically moving bolt, which provides blowback by hitting the rear part of the weapon, WE rifles have a metal trigger mechanism, functional bolt catch (the gun stops firing after the last BB is fired from the magazine) and an adjustable hop-up chamber, allowing you to shoot even heavier ammunition to fully utilize the potential of gas guns and significantly increase accuracy.
