What´s so special with this ??

It´s good to pull the handle from time to time.
Anyway – i´ve said all along – and i still stand behind it – that i don´t want no MS. The Cricket has it but now i´m looking for a good SS tray. I need to get one made out of Delrin or aluminium. It´s in the works.
I really liked the first R3 SS concept and the ease of use. Even the updated R3 SS feels worse – for me. The big problem there (as well as with the new MS) being the PULL HANDLE /load handle being located too far back for my taste. Imagine shooting fast repeated shots ; You´ll look like a moroon trying to swim one-sided crawl on dry land. I can´t have that …

Check one of the solutions for that hard pull: Replace the recessed hex head with a longer M4 to get it more AR 15-esque and ease the pull.

And how to make the mag index 200% smoother. Little patience and a little round file goes a long way …

Aluminium. The action is much rougher than the original, steel breech single shot and will never get to be as smooth. Dr. Evil has polished,tweaked,lubed and relubed it to a umpteenth degree and has indeed got it much smoother but still…
The best of them all , IMO, is the “original” R3 steel breech,bar none.
There´s also an attribute i don´t like on that MS; The breech handle is located very far back. That too makes it feel like the pull is heavier than it necessarily has to be.
