I knew the old MPR FT action would fit into a s400 series stock but I didn't realise it's new replacement would.

Looking at the different trigger guard the HFT500 has would the S400 stock need modifying in any way, or would it be a straight swop?

Is it possible for a private customer or RFD to buy an action from Air Arms without the stock?
