To my knowledge there are no Sample LL's. I got it from Robert Brown at R&R Exotic Machines, was my first machine gun purchase. Since then that weasel has conned me into 10 more this year. =(
Glenn, wherever you found a Sturmgewehr 57/Sig 510 parts kit I will never know. I am jealous, next time there is a shoot I'm bring some Swiss and Kurz for the 44 as well.
Yeah its pretty slow. Im gonna do a gunners vault vid on it in a few months. I just got in an MG08/15 for repair that the owner has given his permission to use on the vault once I fix it. The thing is awesome! Also got a maxim Im building up.
