Muller Modified 4-MI
CYA accuracy fool friends:
The RFBR barrel of the future is the Muller Modified 4-MI....
That is...............
If we can get them....
CYA accuracy fool friends:
The Muller Modified 4-MI is the RFBR barrel of the future, because it can be properly taper lapped without washing out the breech end.......
Because the lap is guided exactly to the same degree on both the forward strokes as well as the rearward strokes..
This means that not only is the breech end not washed out, but the lands are not narrowed at the breech end..
And the proof that the Muller Modified 4-MI is the RFBR barrel of the future, is this:
The most accurate RFBR contraption on Earth, by actual record, uses one.
By actual record I mean, sub 10 MM, 40 plus round test center results...
That's not a misprint......sub 10MM
