I bought the mount, I think maybe from Centerfire Systems, but it was back around 1990. Don't know if it's still available. Only bad thing about it is you can't field strip the bolt with it in place, but yeah, those replacement hoods rattle around and there's just no way one's gonna hold zero. The one I bought bolts down on four corners, two on either side of the action. I drilled and tapped it myself, not that hard to do considering the cheap Chinese steel it's made out of. LOL It came with a proper size tap and bit for the screws and I have a tap and die set out in the shop and a drill press with machine vice. The gun has held zero for a long time now and it shoots 3moa which is pretty normal for an SKS.
And, yeah, I lengthed the stock with a slip on pad because the scope won't mount much further forward, but then, the stock was a little short anyway, though longer than the chinese stock that came on it. It's not a perfect set up, a little tall, but I can see the irons underneath it which is kinda cool.
I bought that light back in the 70s from Gander Mountain catalog and never actually used it, lol. It's a 6 volt, have to carry a big lantern battery in a coat pocket when I use it. I'm stand hunting, not moving. It's at night, can move with it, but I bait hogs. I'd like to see if I could find a halogen lamp for it, but the lamp that's in it is good for about 100 yards and at night, heck, that's decent. I set my feeder up about 50 yards.
What I've added to the gun:
Choate stock.... $75
Ambi safety.......$18
vented heat shield w/ bolted on ... $18
case deflector
five round flush mount mag....$24
scope mount....$35
Lighted reticle 3x9....$40
I also cut that bloomin' useless bayonet lug off it. I was using it as a brush gun locally when I first got it and that thing kept grabbin' brush as I walked. I carry it with the front sight pointing backwards when it's slung, so that doesn't bother me. I haven't hunted with it since I got my .308 Remington M7, so I thought I'd stick that old light on it and maybe I'll get the energy to go sit and wait on a hog some evening. I've used that light a few times on coyote hunts, but not on hogs, yet.
I only gave 75 bucks for the bloomin' gun! ROFL! I got a little carried away dressing the little useless POS up, I guess, but it does look kinda cool if nothing else. That scope is sorta impressive, too. I shoot the thing at the range a lot and it's pretty rugged and has quite clear optics. I don't worry much about recoil with the SKS, wouldn't put it on a 300 mag or something, but it's great on the SKS. It's about a bazillion times higher quality than a friggin' Simmons, anyway, ROFL! So far, it's been well worth 50 bucks. It even has the Euro style focus adjust. I had a 1.5x4.5x20 Bushnell on it originally, but it wasn't a real bright scope for low light. This 40mm cheapo is pretty danged bright! Amazing, just bought the thing at this Homier traveling tool sale they had in Victoria some years ago. Didn't expect much out of it, but got a lot more than I expected. Could hardly see putting a 400 dollar Leupold on a 75 dollar SKS, but then, a 75 dollar stock don't make TOO much sense, either, LOL!
