That's a pretty common issue on the FWB match guns. The carrier gets brittle with age and just breaks.
There used to be an ebay seller that had those, but haven't seen them in a while. Pilkington won't sell parts, but they likely have them. Maybe try Champions Choice? And there used to be a fella somewhere here in the states that sold parts too but can't remember his name.
So this post was absolutely zero help, sorry about that 🙂
AH!
Here you go, I found the guy I was thinking of, Neal Stepp. Be sure to CALL him and see if he has one. I had no luck with email last time. Good luck.
i wrote on this a few months back there are no carriers Neil has none FWB has none the Ebayer in Cananda has none on one is making them
and my point in my post was to state as these trigger carriers fail your rifle will become a wall hanger
Knibbs Chambers Protek Waffencenter the factory I.S.S. not available
could there be some laying in a box or draw somewhere i guess there could be and if so you will have one hell of a job finding them
all FWB 300 owners have a problem and that is the complicated plastic part called the trigger carrier someone needs to tool up and make some out metal, so these old rifles don't end up on a wall collecting dust
it could be done but at what cost would need to be CNC machine made and you would need a new carrier to scan off of or a damn good one
good luck to all that own FWB 300's and believe me i did my research of course one or two could show up but there are thousands of FWB 300 out there and i own zero i was looking for someone else
