I agree about factory barrels.
It is if you don't want to spend more money on a gun.
I never said anything about lapping not being good. It is beyond my skill set and
I did not want to go through the process.
Whatever the UBC adds, it made no difference in my loads.
Your dads car is not a jet engine and cars have many other problems to wear them out. The point is that it works as advertised and so does the UBC in my experience, that is all.
I don't have a bad barrel, it will shoot sub moa with about any load I put in it. I don't think I am going to get a more accurate barrel.
And finally, the whole point was that the UBC makes the fouling lighter and more easy to clean, and that is a plus and a cheap solution compared to a new barrel.
It works as advertised, period. For me.
Prehaps you should get some experience with something before you blather about it. By your own admission you don't use it. What exactly are your credentials? Probably better then mine, but I am not shoving mine down anyones throat.
You seem to be the type to want the last word, so go for it. I won't respond. I have made my points without trying to sound like a know it all. It is up to the readers to decide. Back to silence for me.
