Converted the 410K into a 400K on Sunday when the magazine operating blade snapped after 2 years and several thousand cyclings.
On line order to Chambers on Sunday afternoon and the part arrives first post today, the 410K is ready for rabbit within 40 Hours of breakage...
The bad news? You have to buy the whole post assembly but at a total cost of £9 including P&P, I can shoulder that burden.....
They were very good in providing a service kit for a thirty year old Crosman air pistol that I have. Went to some trouble for bits that cost a few coppers - ok - well a few quid, but not really worth their time.
