Well there is a FAS 604 kit up in the sales section right now for £290.
Ad' text here:
The 604 is a great pistol but look for a Mk2 with the anatomical and adjustable grip. You also want one that has been recently re-sealed and had the felt wiper replaced to ensure good lube distribution internally.FAS604 in very nice clean condition,
Comes with 3 different size balance weights, sight extender, tools, manual, FAS Stickers (unused), FAS embroidered patch (unused) and case (originally Pardini) with combination lock.
Nice complete kit, shoots lovely
£290
Will add pics ASAP
If the seals are degraded, power drops and the pistol fails to punch clean holes at 10m. The pistol I sold on was giving about 370 fps after a reseal. The FAS 6004, the new version has had a poor take-up due to
bad reviews from reported quality issues.
