New pics up on first post. Notice the new "super-cool" flash hider at the muzzle, (I wouldn't want to ruin my night vision with it's
massive muzzle flash

when shooting zombies at night...)

and the extended mag release. Unseen (of course) are the VQ bolt buffer and VQ extractor.
A bit of a note on the extractor:
There is a sticker on the baggie that the extractor and new spring comes in that says "Use factory spring when installing in a MkII/MkIII".
I didn't know that there
were different Mks of 10/22's.

So I went online to find out which I had. I figured I'd be able to tell by using the serial number maybe...? I didn't find anything useful except that maybe there are entirely different firearms called MkII and MkIII. (I'm sure someone will fill me in on this)
Anyway, so I'm not sure what to do. I examine both springs and I notice that the new one is quite a bit smaller. I go with my gut and leave the original in. No workie. It grabbed the rim ok when I stuck a shell in it before I re-assembled it, but once I got it back together, it wouldn't load. It just jammed the shells in at a really steep angle.
So I took it all apart again and put the new spring in. It was kinda doing the same thing at first, but at least the shells were loading if I gave the handle a little nudge.
I took it out to the range to see how it shot and the very first shot stovepiped!

I was not impressed. I figured I'd burn off a few more shells to see if it would keep malfunctioning, but that was it. Just the first one. I fired off over 100 rounds without any other sort of malfunction whatsoever.
I was able to keep 5 shots inside 1" @ 50 yds without too much trouble. I wasn't trying very hard and it was kinda windy. I had a few groups with 3 holes out of five touching, so I'm betting that, with a higher-powered scope, a less windy day and some concentration on my part, I'll be able to shoot 1/2" groups @ 50 yds. Not bad for a plinking and rabbit rifle.
