SA80's were on the Market in the 80's, Pat Walker guns had them (Advertised in Guns Review) , Although there are a few who don't like to see these adverts, I'm sure a few who have posted regarding the bayonets will testify to this. A few of the old adverts, the last one I love regarding the Sherman tanks........ I don't know what £10,000 in 86 would be worth now, but if anyone ever invents a time machine let me know.
