Spring Upgrade
Posted: 23 Jun 2012 00:03
I recently made an attempt to install the spring kit from Brownells in my new Rossi 92 20" in .357 Magnum.
All went pretty well until I tried to install the Ejector Spring which is at least twice as long as the stock spring. In my experience, this long spring makes reassembly virtually impossible, as it must remain compressed in order to install the bushing and slide the bolt into the chamber. Yes, I used a dummy round.
I put the other springs in as well as some modest stoning of the channel in which the trigger is installed to remove drill burrs.
I used the video from Steve's Gunz and it was quite helpful but I worked out the following additional techniques:
1. When installing the new mainspring, it would require Hulk-like strength to compress it enough to get the paper clip back in. Answer: Slide the spring onto the shaft, install the clip between the windings, and rotate the spring to, in effect, screw it in under the pin. Done in seconds.
2. After installing the lever and locking bars (don't mess with the screws, it's unnecessary and they mess up the head-space adjustment which could be dangerous), when you install the pin, make sure it's driven securely and all the way in or you will find you can't open the bolt. This pin MOVES WITH THE LEVER, so it must not protrude into the receiver assembly.
Neither Steve's Gunz or any other procedures I found on the web addressed these issues.
If any one has experience with the ejector spring, I sure could use some pointers.
Thanks,
Jeff
