If you're shopping for your first sidearm or a cheap base gun for a custom Hi-Capa build, the Golden Eagle 3304 Hi-Capa 5.1 Desert OPS GBB Pistol is one of the best options out there. Based on the Tokyo Marui Hi-Capa 5.1 design but treated to a full metal exterior, the GE Hi-Capa Desert OPS is a simple yet functional piece, offering harder recoil and a more realistic feel than the original ABS polymer TM build with the same vast aftermarket of upgrade options.
Inside, this affordable package is equipped with a 6.02mm tightbore inner barrel, enhancing accuracy potential with high-quality BBs while providing a slight FPS boost thanks to enhanced gas efficiency. If you're looking for an affordable gas blowback sidearm with competitive out-of-the-box performance, the Golden Eagle 3304 Hi-Capa 5.1 Desert OPS GBB Pistol is as cheap as they come!

Description
Whether you need a cheap Hi-Capa base gun for a custom project or a solid beginner sidearm with plenty of upgrade potential, the Golden Eagle 3304 Hi-Capa 5.1 Desert OPS GBB Pistol is one to watch. A full metal clone of the TM Hi-Capa 5.1, the Golden Eagle version brings harder recoil and more realism to the proven Hi-Capa formula.
Inside, we're even treated to a 6.02mm tightbore inner barrel for an accuracy edge with high-quality BBs, a very generous pre-upgraded inclusion in this bargain package. If you're after a full metal beginner sidearm with plenty of aftermarket customisation options and solid performance straight out of the box, the Golden Eagle 3304 Hi-Capa 5.1 Desert OPS GBB Pistol is a solid choice!
Starting at the front, we can find 11mm CW female threading at the tip of the 5.1-inch aluminium outer barrel, allowing a tracer unit or suppressor to be fitted using an 11mm CW female to 14mm CCW male thread adapter. If you're planning on rocking a tracer with the 5.1 Desert OPS, we recommend the Eshooter Flare-M, as it is supplied with the correct adapter in the box.
The outer barrel itself is finished in gloss chrome silver, providing a glimpse of its glamorous colour finish through the mock ejection port on the right side. The slide is a modern, squared-off design inspired by STI 2011 pistols and, of course, the Tokyo Marui Hi-Capa 5.1. Slide serrations can be found at the rear, providing extra traction for ease-of-use in wet weather conditions or when wearing gloves.
The sights of the Hi-Capa 5.1 Desert OPS can be found on the top of the slide, a set of open sights with a fixed front blade and an adjustable rear notch. The rear sight can be adjusted for elevation by turning the screw on the top, and for windage by turning the screw on the right side, using a flathead screwdriver. The rear sight is a serrated "anti-glare" open sight, making the sights easy to acquire, even in bright sunlight.
The slide release catch can be found on the left side of the pistol, just above the trigger, and is a slightly enlarged design to enable those with smaller hands to use the control effectively whilst remaining tight to the frame to prevent snags. The magazine release can be found on the left side of the grip and is a standard profile, giving you a perfect happy medium between speed and security.
The grip itself is constructed from high-density polymer and features crackle texturing on the sides, with pyramidal texture on the front and rear. This provides the gripping qualities necessary for use in all weather conditions, with or without gloves. As a part of the Hi-Capa design, the trigger guard is integrated into the polymer pistol grip module, a squared trigger guard with a flat front face. On the front face, we're equipped with gripping texture for the support hand, allowing you to keep the muzzle flat during rapid fire using the "European Grip" technique.
At the base of the grip, we can find a low-profile magazine well flare, integrated into the grip module. This part is intended to help speed up reloads by providing a widened route to the magazine well, allowing for "eyes up" reloads and easier reloads on the move. While this isn't as wide a flare as competition-style Hi-Capas, it still does its job while maintaining a more military-esque aesthetic.
The manual safety catch can be found at the rear of the pistol, and is mirrored on either side to allow for left or right-handed use. This manual safety can be activated whether the pistol is cocked or not and will lock both the trigger and slide when pushed upwards. When not in use, the safety does double duty as a "gas pedal" style thumb rest to encourage a consistent grip and assist with controlling muzzle rise during rapid fire.
At the rear of the frame, we can find our secondary safety device: the "beavertail" grip safety. This safety prevents the pistol from being fired unless it is pressed in, ensuring the pistol will not fire when dropped and allowing you to safely carry the Hi-Capa, "cocked and locked", with its legendary light trigger. The beavertail present on the Hi-Capa 5.1 Desert OPS is an extended design, featuring texture on the rear surface for additional grip and an extension to ensure the safety is disabled as soon as the pistol is gripped.
Just above the grip safety, we can see the hammer, which is a low-profile skeletonised design intended to reduce the chances of "hammer bite" and prevent the hammer from snagging on your gear as you draw. The angular design of the hammer sits right in line with the visual language expressed by the rest of the pistol, and also includes linear texture on the upper surface to allow for greater control if you need to de-cock the Hi-Capa.
If you're looking for a solid sidearm to fill your holster or a bargain backup with plenty of upgrade options, the Golden Eagle 3304 Hi-Capa 5.1 Desert OPS GBB Pistol is a fantastic choice. A full metal version of Airsoft's most popular sidearm for a price which is hard to believe, the Hi-Capa 5.1 Desert OPS makes a great value starter sidearm!

Joule Charts
Special Instructions
These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
