Strike Planet gives an overview video on the G&G versionn of the H&K M27 IAR, the G&G GC4-16 IAR AEG... "This is an airsoft replica of the increasingly popular M27 IAR, which is essentially a heavy-barreled version of the HK416. This copy in the unsurpassed performance of the company G&G just copies the machine gun version of the 416, which was intended to replace the US Marine Corps, oddly enough, light machine guns M249. Externally, the drive is made of high-quality aluminum alloys, on the face of high quality processing, no burrs, flash, streaks or other flaws. Inside there is a gearbox of the second version with a good filling, confidently holding 130+m/s, which is very worthy for an emka out of the box. The drive is equipped with a high-speed motor, which is ready to meet with stiff springs. The telescopic buttstock with a spacious battery compartment allows the use of high-capacity batteries, nunchuck-type assemblies are ideal."
