You can bypass the trigger contacts completely and also introduce other features such as trigger sensitivity and precocking - potentially at least. Depending on what other upgrades your SVD has, there are other areas you could address but I have to confess I haven't seen much information out there regarding compatible upgrades. As far as I know it's a lower-quality clone of the Classic Army SVD and also has some proprietary parts in the gearbox but please, don't take my word for it - do some research on other forums as there must be some end users posting. Hopefully!
May be worth considering the CYMA SVD, it's a much more well-regarded replica and is based on the Real Sword platform. There's a great deal more information out there too but in either case, good luck.
