in green gas


Yes, another low end Gas Blow Back rifle. This time it’s from Jing Gong. It’s based on the WA system. First impression is that it’s like an improved AGM. Everything seems sturdier and a little refined, at least not worse. The bolt stop is spring loaded. There’s a realistic looking gas tube and the mag is tremendously lighter (ca. 300g less) and has a stiffer spring than the AGM. Bolt stop action works flawlessly and always locked the bolt back after the last round shot. The body is made of decent plastic. How long it’ll last on green gas I don’t know, but it didn’t make a weak impression. The trademarks on the body look cheapo. The fps test was conducted at around 22 deg Celsius with green gas. The first couple of shots were around 410fps, the rest averaged at about 390fps. If you plan to replace the body anyway, then go for the JG.
