"NA BEAN DON CHAT GUN LAMHAINN"
Believe it or not these work quite well. Some have used them on the M77 in .308. I have only used them on AKM's and AK74's with medium sized scopes etc.
Worth a try for the price.

"If they’re going to come here illegally, apply for & receive assistance through a corrupted Government agency encouraging this lawless behavior, work under the table & send billions of dollars each year back to their families in Mexico, while bleeding local economies dry, protest in our streets waving their Mexican flags DEMANDING rights, while I have to press ’1′ for English, then they need to be shipped back to where they came from!" -Chad Miller
