Reapers Airsoft review the Gas Blowback HK416D Made by KWA and it is fully licensed one carred by Umarex... "Hello people, in this Review/Test we look at the KWA HK416D Gas Blowback. Since the differences to the HK417 are not very big, we have kept it a bit shorter this time. Also with this model the processing quality and the circulating gas system could convince. The internals we find out of steel ensure a long service life. Even the magazine which unlike other GBB models like a whopping 40 shots, but does not seal 100% to Nozzle, which can lead to smaller gas clouds again and again. Unfortunately, the 416D comes without NPAS, but you can fall back on a Nozzle LM4. Since this model was also recalled by Umarex, we did not include the shot test in the conclusion! As with the HK417 A2, the HopUp Tenisioner would have had to bend a bit to get better results."
