Yes, I am a purist when it comes to the collectible guns such as my '52 Russian SKS. Even my all matching Chinese letter series C&R SKS I consider a piece of history and won't alter it, same with my run of the mill Mosin Nagant 91/30. That said, this is my SKS Sporter that I have indeed tinkered with. I often refer to it as a M just because it no longer has the Sporter thumbhole stock but it is a Sporter. Here is what I have done with it:
1. Ditched the thumbhole stock and replaced it with a regular SKS stock that I modified to accept the metal mag well liner from the thumbhole stock. I painted the metal stock hardware black. I sanded and refinished the stock but I may strip it and do it again as it came out too red for my liking.
2. Sent trigger group to Murray for his made in USA hammer/sear/trigger set and trigger tuning (it's really sweet now too).
3. Added a Scoutscopes scout mount.
4. Added a Sightmark green reticle reflex sight.
5. Added a custom rail that fit into the spike cut bayo slot on the stock.
6. Added a rail extension to the bottom rail.
7. Added a cheap light/laser combo to bottom rail (came with a remote switch but my off hand puts my index finger right at the switch on the back of the light so I'm just using it that way for now).
8. Added a made in USA cheese grater hand guard.
9. Added a 1 inch rubber stock extension.
That 40rd mag is not mine, it belongs to my friend. I only have 5 and 10 rd mags because I didn't want to register any high cap mags in CT so I gave them all to my brother in Utah. This gun is 922r compliant and is not only legal in CT it doesn't even need to be registered like ARs do because it only has the detachable mag, no other evil features. If I can prove it was manufactured in 1992 like I think it is then it qualifies under CT law as pre-ban and I could then have a pistol grip, forward pistol grip, flash hider, etc. I may pursue that later. Take that CT!
Here are the pics, enjoy!
