Here's a list of changes you have to make before the g/l will work:
In ADDONINFO, change the cyrillic entries to these:
"40 ìì" -> "40 mm"
"40 ìì (ðóñ.)" -> "40 mm (RUS)
"12 êàëèáð" -> "12 caliber"
"40 ìì (ÐÏÃ-7)" -> "40 mm (RPG-7)
And while you're at it, change this as well:
"ÑÂ98" -> "SV98"
to get the SV98 to accept the intended bipod.
As for the burst fire, I have no solution. I suffer from it as much as you do. If I come across a solution for it, I'll let ya'll know.
Good luck and don't forget to save often
