Planning to make a Ruger Mini 14 in .300 Whisper

[Buckshot]

Hello.
I am planning to buy a cheap second hand Ruger mini 14 (Ranch) rifle.
This should be converted by aplying an adjustable gas tube.

The barrel should be replaced by a Lothar Walther 13.5 inch barrel.
Stock should be replaced by either a original Ruger folding stock, or a Ramline type.

Does anyone here have any experience with converting a mini 14 to .300 Whisper?

I also would like to get in contact with someone who does have an original stock for a mini 14.

Since they are hard to get, I am considering to build one by myself.
(At least ,I hope this will be possible)

If anyone has got any usefull info, please let me know.

Sincerely.

Buckshot
