Air Arms S300 .177 mag conversion?

[SJC]

Afternoon all first post so here goes.
I have recently bought the above rifle and have been trying to source the .177 mag conversion kit but unfortunately it seems that they are only available in 22 calibre (Rowan Engineering), however I’m sure I have seen/read somewhere that the s400 conversion kit will actually fit, now before i shell out £70 odd quid for one could someone please confirm this, i also wondered if the s200 may fit also.
Any help or information would be very much appreciated.
Thanks in advance
Steve

The airarms S200 kit won't fit, Rowan should be able to sort you out, they do .22 and .177 for the S400 give them a bell. Rog

Welcome to the AAOC.

The S200 won’t fit and I’m sure the s400 will.
There’s also two different bracket sizes.
Give Dave or Derek a ring at Rowan Engineering and they will advise.
They are a great bunch and well known to myself and the AAOC.
