APEX R5 M12 Carbine GEN2 AEG




APEX R5 M12 Carbine GEN2 AEG

The R-Series is the next evolution in Apex's 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 tight bore barrel and the metal rotary hop-up unit come 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 wire cut steel gearset for superior durability over powder metallurgy or casting techniques. The low resistance wiring now features a MOSFET circuit that bypasses the trigger switch, resulting in superior battery efficiency, trigger response, and heat management. A high-efficiency Deans plug is standard, although a mini-Tamiya plug adapter is included to provide maximum flexibility for battery types.

Please note: the original R5 M12 has been discontinued.
