Having run the CETME thru HK thru PTR variations for years, my conclusion is that that the PTR is not only better than the factory rifles as far as fit and finish is concerned, it is the best...period.
That might explain a milk carton I saw with a picture on it of an empty 7.62NATO casing with the words "Have you seen me" above it.Yes it beats up the brass but its not an issue since it lands in the next county anyway. I had no idea that the firing and extraction process could be so violent.
PTR needs to make an MP-5 semi version.
They would sell a ton!
