It's not compatible with VSR parts, except for the hop-up rubber and possibly the barrel. I'll be opening mine next week when my replacement hop-up rubber comes in, so I'll be able to confirm then.

But know that it works very well stock. The hop-up is weak, so you would need either a bigger nub or a new hop-up rubber to shoot heavy ammo. Otherwise it's pretty consistent for a stock gun (+- 4 fps with MadBull Bio 0.32g BBs with the one I have, +- 6 fps with horrid Valken 0.36g BBs). It sits right around the usual field limits with 1.55 joules effective with 0.20g BBs (408 fps average) and 1.44 joules effective with 0.36g (293 fps average, it seems like it's a bit undervolumed, maybe a better hop-up rubber would help, I'll know soon). I'm pretty satisfied with the stock performances, and seriously only plan to change the hop-up rubber.

With that said, TNT makes upgrade parts for it. They make a complete spring, piston, spring guide stopper, spring guide, cylinder head and sear set (https://www.switairsoft.com/product-...8k-upgrade-kit), they also make an upgrade hop-up chamber (https://www.switairsoft.com/product-...powered-kar98k, which is probably useless) and a hop-up chamber and barrel kit (https://www.switairsoft.com/product-...m-retrofit-kit).

The reviews on upgraded S&T/Snow Wolf Kar98k show great accuracy, reports from some experienced players put it right in VSR10 territory for performances. It's doesn't have the air volume to deal with extra heavy ammo like a VSR10, but it's still performing very well with weights around 0.36g-0.40g (according to reviews, and once upgraded). I can't report on long range accuracy right now because I have yet to field it, but in my basement at around 12 meters, I get a 100% hit rate on 2.5in/6cm popper targets. The rare times where I miss, it's always my fault.

I've been recording stats with it, for fun and giggles, I made a Google spreadsheet with it :https://docs.google.com/spreadsheets...it?usp=sharing

I'll update the spreadsheet when I get 0.40g and 0.43g BBs later this week, and will probably test it again with a Maple Leaf Autobot rubber to see if there's any performance difference, and if a tighter rubber helps with the limited air volume. This might also be one of the rare bolt action rifle where a 6.01 tight bore barrel is actually a good idea.

So overall, a greta gun so far. The fake wood is the best I've ever seen in Airsoft. The best part is that the bolt doesn't close when your mag is empty, so no dry fire. We'll see how well it holds up in a few months/years. But knowing that TNT makes upgrade/replacements parts gives me some peace of mind.
