Matchguns?

[Lefty]

Has anyone tried mounting the sensor to a Matchguns MG2? No place for Picatinny! Some folks are very critical of the barrel mount, but I wonder if it might be okay. Is the part that goes in the barrel made of metal or plastic?

Hi, I own an MatchGuns MG2E and I am using Scatt's barrel insert to my full satisfaction.
I think the part that goes into the barrel is made of a hard type of plastic. The barrel will not be damaged by the insert, and remember as always do not overtighten

Excellent! Thanks!

I will clarify that on the unit that I received today, the barrel insert is made of brass. The pin that expands the barrel insert is covered with tiny brass shavings, as are the threads of the screw that moves the pin. I cleaned it as well as I could with barrel cleaner but some shavings are still present. I highly recommend cleaning your barrel after using this insert, before live fire.

It is made out of soft metals (to eliminate any chance of the mount damaging your steel barrel)
It's usually aluminum and sometimes brass (like the one that Lefty got).

And yes - if you get some shavings/tiny imperfections, feel free to clear it all up with polishing (micron) sanding paper.
Don't be afraid to remove the black oxide whatsoever and leave the metal showing
