You had the first in the world March 2012, done legit by an RFD and three barrels.
First time anyone saw the second was 2013.

Bit late but thats them horrible probe type Sven that constantly pack up and its bad p[ractice to rely on inferior guage built in. Op asking for whats the most common in US the Fosters or early AA style over here. Steyrs are drilled out of solid, theres no end plug to swap over and idealy need machi...

From memory you can enlarge to 14mm and just about get away with existing arm.

Will need a new cocking link as well the one with serrated edge. Heres one done earlier sold in 2003. https://pic20.picturetrail.com/VOL15/728921/1313294/132412740.jpg Theres one in this one from 2002, taken out 2004 and sent to Sweden. No benefit https://pic20.picturetrail.com/VOL15/728921/1313294/...

The Diamond are made or should i say assembled in Japan, same factory that produces Sightron S3 and Falcon X50.

Yes its been around since 2005 with the 8002 S1

2002, 2020, 2025 stocks were different.

9015 same stock just a colour change to grey.

Best stocks were the 2004 9003 but the grips who ever designed them wanted sacking as said in 2005 to the factory.

Its what we call caggy handers Adrian.

Kahles wheel upside down?

My thinking Sven as is yours done that way.
Why bother with a tool or even change the power adjuster for another and have no access unless remove from stock = stupid idea.

All mine well over 100 have hacksaw slots in rear.

Seen loads of them Sven, no matter what you do baring in mind to retain guarantee 1 in 3 you will not get above 771ft/sec. First one encountered pre release would go to 840 ft/sec. Nothing changed just the different German parts made at same time drives you round the bend. Just a dirty cheap way of ...

10M to sub 12ft/lb the only difference is the factory pulled a fast one and just turned some of the standard 10m reg body away to 14mm dia. Not bad $200 for 3 minutes work, i'll be a millionaire before the years out there again it wouldnt carry my name. Hammer spring wont make a scrap of difference ...
