Bolt spring ,Sight rail and Dry fire.

The bolt spring was cut from an old hand saw.
It was so easy to do, up until I had to drill it. I killed my 3mm and nearly killed my 4mm drill bits.
Ah well I will have to buy some more!
The Sight rail which is dovetailed was straight forward, except
It took an age to recess the underside to hide the bolt spring body, I used a 5" grinder with a 1mm disc to remove the material.
It does not look pretty but its all hidden under the rail.
The Dryfire is a straight forward, gravity pin, which does the job.
I was very pleased with the results.
