Viken Airsoftspill gives his take on the APS UAR 501X AEG, the airsoft gun used as gun prop in "The Expanse", one of the best sci-fi TV series ever made... "This is an honest review of the APS Urban Assault Rifle Black 501X.

If you choose to by the APS UAR 501 make sure its the X version. XB or XT. Reason is the gearbox is Lipo ready, improved and has a mosfet. It has an excellent trigger response for a Bullpup, and a great price tag. Is it the best Airsoft Bullpup on the market? At this pricetag it is.

I've tested it indoors, speedball outdoors and a two-day milsim game.

It chronos stably around 1.17 J with .25 BBs. Same as 350 fps measured with .2 BBs. APS has done a good job with this."
