Rapid stocks-which ones fit which actions?

[Rapidnick]

Getting a bit of a headache here ladies and gents. However it is an important subject for those of us of the 'Rapid' persuasion so here goes! The following is NOT guaranteed.

A Rapid 1 action will fit the following:
A Rapid 1 stock- without modification
A Rapid 2 stock provided the bottle is moved forward by using some form of spacer such as a Theoben Pressure Guage (rare to find one at all let alone still working) a regulator or a threaded tube.
An MFR stock would need a lot of cutting at the fore end. Probably not worth it in money terms as a R1 stock is usefully cheaper and the value of the MFR stock would be reduced.

A Rapid 2 action will fit the following:
A Rapid 2 stock without modification.
A Rapid 1 stock provided that the R1 stock has 2-5mm of wood removed from the inside of the back of the stock so the securing bolt hole lines up correctly AND the bottom of the stock is inlet to accomodate the circular cover found on the underside of the R2 action-easy to spot AND some wood is removed from the trigger slot. There is an issue also with the trigger guard as the R2 action is not supplied with one.
The R2 action with 400cc bottle will NOT fit an MFR stock without substantial cutting of the fore end. OK with 280cc bottle though.

An MFR action will fit the following:
A MFR stock without modification
A Rapid 2 stock without modification. This will leave more space between the (smaller) bottle and the fore end wood.
A Rapid 1 stock assuming it is cut as if a R2 stock was to be used.

Please note that a R2 stock designed for the Anschutz trigger-with safety cut out on the right side of the stock-which was fitted to the first few R2 actions made, is effectively a R2 stock for the purposes of this guide.

Please feel free to confirm, correct or add to the above statements. I think some kind of permanent reference would be very helpful as this topic comes up quite often.
