Optics shown in images not included. The R-Series is the next evolution in Apexs mission to bring you a feature packed AEG at a surprisingly good price. The R-Series is centered on a new aggressive receiver design, one that instantly differentiates the Apex brand from the multitudes of M4 clones on the market. The R-series receiver combines practical function with updated combat rifle styling. All controls are fully ambidextrous.

Internally, the R-Series uses the same gearbox as the Mark 13 series, but with the electric blowback function removed for better battery performance and piston lifespan. A 6.03mm tightbore barrel and metal rotary hop up unit comes standard. Every carbine length R-Series shoots approximately 400 fps, and every CQB length R-Series shoots approximately 360 fps.

The new GEN2 builds on the R5 platform and incorporates numerous enhancements to the internal function of the gun. All gearbox polymer parts have been replaced with a high heat tolerant polymer, including the trigger switch and piston. The gears have been upgraded to a wirecut steel gearset for superior durability over powder metallurgy or casting techniques. The low resistance wiring now features a MOSFET circuit which bypasses the trigger switch, resulting in superior battery efficiency, trigger response, and heat management. A high efficiency Dean's plug is standard, although a mini-Tamiya plug adapter is included to provide maximum flexibility for battery types.

The Apex R-Series builds on its tradition of being Always Predator, Never Prey.

"I'm disappointed in this gun, for a $300 gun it should not have the design flaws this has.

Firstly, the barrel is WAY heavier than the back of the gun, resulting in the gun always wanting to tip forward. It appears, they chose a very heavy metal for the front, very bad choice, instead they should have used a lightweight polymer to even out the weight of the gun.

Secondly, the trigger feels cheap, I mean come on, the trigger is where the user uses the gun the most, the least they could do is add a good feeling trigger. Instead, it's not smooth, clicks, and sounds and feels cheap.

Not only does the trigger emits a cheap sound, but the gun itself does too-- a loud one. It sounds like the internals are completely made of plastic.

Very sad.

If I was to rate the accuracy on a 1-10 scale, where 10 is Bullseyes at 100 feet and 1 is not even hitting the target, I would rate this a 6.5.

Hand grip isn't the best either.

In the end, I returned it for a refund and got the G&G Predator
