Although I'm somewhat of a purist when it comes to preserving or restoring milsurp rifles, I have been known to let loose every now and again. For example, after owning several variants and examples of SKS rifles, I felt the design might lend itself to better accuracy if a few (ahem) modifications were done to the basic rifle. Nothing exotic, just some of the same things that folks do with other rifles to tighten up their group sizes. So when a friend offered me a neglected Norinco SKS for a good price, the wheels were set in motion. The kicker was that he had replaced the receiver cover with a scope mount version that just plain didn't move, meaning that particular variable could be factored out. So I jumped in with both feet.

My aforementioned friend had ground off the bayonet lug, which I considered to be a good start in the barrel harmonics scheme of things. The cut-off disk on my Dremel made short work of the remaining front sight barrel sleeve, leaving a smaller-diameter portion of the barrel hanging out there in front of the gas block.

No big problem there. I've had this Capco, Inc. SKS muzzle brake for a while, waiting for the right time to make use of it. It's made to be sweated on or Loc-Tite mounted to a naked SKS barrel after the front sight barrel sleeve is removed. Voila'!

Since the Dremel was already set up to carve things, I removed the side sling loop off the gas block and cleaned things up there for some touch-up blueing. Of course, that leaves no place to mount the sling on the front end of the gun, or does it? Piece of cake. The cleaning rod hole in the forward stock ferrule just received an Uncle Mike's threaded sling swivel post, with a Nylock self-locking nut on the backside holding things tight. The sling swivel needed a slight flat ground into the side nearest the barrel, but that was accomplished easily. The results look fairly clean, with a minimalistic feel, while also blocking off the cleaning rod hole. For use on the bench, the sling removes easily from the front and back sling swivels.

Since the back end of a standard Oingo-Boingo wood SKS stock doesn't have an Uncle Mike's sling swivel, I had to improvise. So improvise I did. The rifle now wears a Ram-Line synthetic stock, with aforementioned sling swivel factory-installed. Nice, huh? :D The real reasons I went with the Ram-Line are rather simple - lighter weight, great ergonomics and length of pull, and plenty of surface area to glass bed the action in all the right places.

Speaking of saving weight, take a look at the gas tube and handguard. Or rather, finned gas tube sans handguard. I wanted to offset the weight gain caused by the scope, mount, and muzzle brake. I think I did it, although I don't have an accurate scale to compare, and the gun is no longer in it's original as-issued trim for the comparison. It feels lighter, and handles amazingly well after the surgeries that removed the front sight base sleeve, handguard, wood stock, and original 10-round magazine. (Replaced with a svelte 5-round zytel model)

The scope is a plain-vanilla Weaver K4, steel tube, fine crosshair. I've found these old scopes to be utterly reliable, and capable of handling hard knocks and autoloader recoil without missing a beat. Nor do they overwhelm the rifle they're sitting on. The 35mm or so objective lens keeps the scope tube centerline lower for a better cheek weld on the stock. It just plain looks good, too.

I've got a steel brass deflector mounted to the rear sight for now, using wiretie zip-straps. It works, but as soon as I figure out how to remove the rear sight tangent from the sight base, I want to drill and tap the tangent and properly attach the brass deflector. The vigorous extraction and ejection of the SKS demands that I protect the scope, even if it is a steel-tubed relic.

As seen in the pics below, the gun is not quite done. I've yet to do the glass bedding of the receiver, and the trigger group is getting sent off to a friend for one of his wonderful reworks. The safety lever is getting shaved down to about 1/4" wide, so the paddle doesn't snag my trigger finger during firing. The pistol grip stock moves one's reach a good bit to the rear, so either I get finger extension implants, or shave the safety a smidgen.

Even though the project has a ways to go, I couldn't resist grabbing a bunch of my 7.62x39 match handloads, and punching some 100 yard targets with the FrankenSKS. I'm not at all discouraged so far, the gun is hovering right at the 1" mark, center-to-center, for 3 rounds. I figure when the glass bedding and trigger job is complete, that'll be 5 rounds inside an inch, then we'll go for adjustments to get surplus lacquered-steel ammo shooting tight groups, too. The funny thing is, even though I hacked up this SKS to make a target gun, it may very well turn out to be a fun Wisconsin whitetail rifle, too. Not bad for a diamond in the rough!

I gotta say - that's awesome! I would love to see what you can do at 200 and 300 yards, since we hear over and over how the 7.62x36 is not accurate out of an SKS or AK beyond 150 yards.
 
Very nice! I think I may have to pick up an SKS and try accurizing it as well.

Tell us how it shoots farther out when you try it!
 
Range tests longer than 200 yards will have to wait.

At least until my USAF retirement goes official. Then I can move to a location that has ranges greater than 200 yards - I've got my eye on the one in Lodi, WI. ;)
 
:) That rifle is a thing of beauty!
You have done well to prove that semi-automatic military rifles do indeed have purpose as sporting firearms and I congradulate you on your effort.
 
That is one nice looking rifle. I didn't know SKS's could look that pretty...or shoot that well. Good job.

What could you do with Mosin?:evil:

Beeeeyoutiful SKS!

Sweet. Very sweet. Nice looking firearm, and I am in a fit of envy re your accuracy report. (One of my favorite gun quotes is the revered Col. Townsend Whelen's: "Only accurate rifles are interesting.")

Questions: 1. WHERE in a Ram-line'd SKS is there any room to bed the action?? In mine, the magazine takes up most of the space, and the trigger group pretty much eats up what's left. I bedded the back end of my bbl, then inserted a very thin shim for tightness, but that seems to have no effect on accuracy.
2. How much improvement do you expect from the trigger job, what really is done, what's it co$t, and to whom do I send mine?

I guess here that imitation is the sincerest form of flattery. Apologize if I'm overstepping the bounds of propriety, but I too would like an SKS that does better @ 100yd than to keep 'em in a bucket.
 
Unfortunately, no updates.

It sits in the safe, ready to go. My two favorite shooting ranges have been closed, one permanently, and the other is still awaiting repairs from last fall's double hurricane whammy. Can you say "itchy trigger finger"?

The mount is somebody's receiver cover unit, I normally don't put much faith in them, but I found this one intriguing because it just plain doesn't move. It's also a gold-plated b!tch to install that last few millimeters. ;)
 
Excellent work. Looks real good.

The kicker was that he had replaced the receiver cover with a scope mount version that just plain didn't move, meaning that particular variable could be factored out. So I jumped in with both feet

You wouldn't happen to know the maker of your scope mount? There are very few mounts for the SKS that hold zero. I have a beater scope that I'd like to try on my Yugo.

Umm....

Its nice, I like the look alot but what the others have posted about distance I cant agree with. First off Im a Marine and I just came home from my first deployment in Iraq, so dont bull**** me I know what im talking about and if I dont Ill find you an answer. The sks is a old design and was designed by simonov and fielded in 1956, just a year before the Ak-47. The 7.62x39mm short annunition has at best a max effective range of 400 metres. Once again though I have personally proven this fact wrong. Just recently on my leave block I made a shot out to 600 metres in the black with my own chinese sks. Which I have fitted with a Tap sk66166B T6 Coll stock and rail mount for my scope. I have also attached a new superlight bipod and new twist on Competition SKS muzzle brake to tighten my groups. All in all I would say it depends on the shooter, but it is possible to pull off shots over 400 metres. If you have any questions I would be more than happy to help you out with the correct answer...
 
That is one of the coolest looking "custom" SKS's I've ever seen.

How's the brake do on recoil and noise?
 
Well...

Gewehr, it's been 3 years. Are you out of the USAF? Have you gone to Lodi with the Franken-SKS? Results?

BTW, I'm very envious. Have been working for years on the SKS myself, have yet to improve on minute-of-pie-plate performance. :barf:

Have already glass-bedded one in a Ram-line. And I roll my own, none of your steel-cased Commie stuff, thank you. Results as to accuracy: Waste of time. :mad:

I know, I know, send the trigger group to Kivaari and be done with it.

Yeah, well...
 
Wow, zombie thread.
I'll guess at the risk of being wrong:
(1) That scope mount ended up not holding zero between shots, let alone cleanings.
(2) The brake popped off and landed about 10 feet down range after the first 20 shots.
 
I hate to revive this thread, but I found something important to add in it. In another forum, a user of the same name, gewehr98 claimed to have finished this project, with bedding, a kivarri trigger job, and a modded safety. He wasn't kidding about the scope mount, he said it was over-sized in the right places, and requires a mallet for the last bit. Apparently it's 1 MOA accuracy, from an SKS. He realized the dream.

He also said, you hae to use good ammo. Crap ammo results in 2 MOA "when lucky" which is still good, if you ask me.
