Thread: KG 12 copper remover

Same here, tend to use a foam cleaner most often.

Non toxic, easy to use and good results.

Here is a not-so-good barrel. Looking down with a normal torch it's not possible to see anything untoward and in fact it looks clean and in good condition. But dig a little deeper with the videoscope and you can see its pretty ugly.



Here is something else that's ugly, just for a bit of fun:

What the Turbine Blade should look like in service...



... and what it shouldn't look like in service...

No amount of KG12 is going to bring back that turbine blade!

One good point from those photo's is that even the crappy looking US barrels shoot ok even if they look bad through a video scope.

I agree 100%, Mooseman. I have a good friend who keeps telling me I need to re-barrel one of my old favourites because - as he says, the rifling is completely f**ked. Yet it continues to put cheap factory ammo into a 1" target at 200 metres. I for one would not want to stand in front of it, even at 500 metres.

Theres hope for my project yet then.

Great pictures.

After closer inspection (below) The Doctor believes that aqueous ammonia could also be considered as an effective & inexpensive alternative for copper removal as long as it is not left in the barrel for hours on end. A clearly visible Tardis colour from fouling. Available in most advanced civilisations.

I use the MPro-7 line of products. I have always found them really good and I can normally clear out a few hundred rounds of copper down to the steel in a couple of runs through. I let the copper remover sit for about an hour and then clear it with gun cleaner and then reapply copper remover.

I agree with the borescope, often you can find things that aren't really an issue or get upset that your brand new barrels rifling has tooling marks in it etc.
