Just bought an Xisico XS-B20 for £50. Stripped it down for maintenance, having just done an HW 99S I was able to compare the build quality. On the internet the B20 is often compared the HW 95, but my 95 is a much bigger rifle, it is definitely a clone of the 99s. Has a high quality polyurethane piston seal, a good fitting metal piston sleeve and a nice cocking shoe on the cocking lever. The transfer port looked rather small so I opened it up to 3.2 mm. The trigger is a Rekord with the automatic cross safety. Do not know if it is a genuine Weihrauch, it is identical except for some levers finished in oil black instead of the silver finish on the HW. Perhaps some experts out there will know. Left the original spring in and with the transfer port opened it is on 11.6 ft.lb. Very easy to cock, and a smooth action on shooting in a light package.
