I have a Proto SLG '08 and am having problems with the feed neck and rail.
I haven't found a single hopper that will fit in the stock feed neck. Anyone have a suggestion for a new feed neck that will fit the SLG?
Also my rail keeps on coming loose, anyone else having that problem?
buy a new feedneck
look at sig for upgrade thread
as for your asa coming loose, read the manual, it tells you how to tighten it
