DIY Laser Colliminator
I have been researching on the web for DIY laser colliminator plans, all seem to use keyring lasers but point out that the laser itself is mostly spraying out and not central....... HOWEVER most gun shops have laser bore sighters, they are machined to a half of half a hair to be chambered in the rifles chamber... ie they are a precision laser..... if not then no gun owner would consider using them.
Just think of a hollow nosed bullet but instead of a air chamber in the nose, the bore sighter laser emits from there.
They cost $35.00.
Just bought one am am now heading for the workshop.
