||I have had this gun for about 4 months now and I am very happy with my purchase.
External Build Quality:
The upper receiver is very high quality machined aluminum as is the outer barrel. The top rail is machined directly into the upper receiver. The bottom rail is machined aluminum, while the side rails appear to be steel. The lower receiver is a VERY tough plastic The folding adjustable stock is made from the same plastic as the lower. The stock has a bit of play in it, but is very durable and servers its purpose flawlessly. The flip-up sights are also very high quality and fully adjustable for windage and elevation. The ambidextrous selector switches are metal and give a positive click in each position.
I disassembled the gun to install an m120 spring. I noted the following regarding the gun's internals. The gearbox is full metal, and can only be removed by carefully prying the lower receiver open after removing it from the rest of the gun. The selector switches are mated to the gearbox with small gears rather than a shaft all the way through (this makes it tricky to remove/replace the gearbox). The gearbox has full metal gears supported by ball bearings resulting in very good durability and low resistance. It features a metal cylinder, polycarb piston, aluminum piston head, and a metal spring guide with bearings. This gun comes standard with many internal parts that would normally be after market upgrades.
The gun performed very well stock with a muzzle velocity around 315 fps with .2g BB's, and good accuracy. After upgrading to an m120 spring and a 9.6 volt battery, it fires at 350 fps with .25g BB's with significantly better range and accuracy. After the upgrade I can consistently hit a plate sized target at 120 ft. The included hi-cap mag also performs very well, feeding flawlessly on both full and semi-auto firing modes. This gun has gotten a lot of use with probably about 8000 shots fired. It has been banged, dropped, soaked in water, and had its barrel plugged with mud and through it all it has always functioned flawlessly. The only thing that could make this gun better is a precision barrel to improve long range accuracy.
High Quality Gearbox
Easy to Upgrade
Only fits mini sized battery.
Gearbox is a pain to remove / replace.
This gun may be expensive, but it is absolutely worth it for a durable, high performance, highly upgradeable gun. If your serious about airsoft and can afford it, you should definitely buy this gun.
