Full Auto SKS

[Chevytuff19]

If I wanted to make my SKS fully automatic, could I sell it to a Class III dealer, have them make it fully auto, and then buy it back from them and register it so it would be lega? If so, how much do you think something like that would cost? Thanks for any help.

You can't. Here's why:

1. ANY machinegun registered after May 19, 1986 is not legal for civilian ownership.

2. ONLY Class II manufacturers can manufacture new machineguns. They can only sell them to government entities and poilice departments.

Sorry. :(

And reason #3, there are no Machine Gun parts for an SKS that were registered prior to May 19, 1986. So you can't do a drop-in conversion, like on an AR-15.

And reason #4, the SKS was never designed to be full auto. Even a legal conversion, would be a custom job.

Reason #5 The SKS is a POS.

Of course, depending on the SKS you have (Chinese ones are good for this), you could always disassemble the bolt carrier, pull out the firing pin, reinsert it upside down, and if you could get it all back together (hopefully the pin that holds the extractor on the bolt will stop you from doing this, but don't count on it) your firing pin should jam in the forward position, forcing you to slam-fire every round in the magazine at full auto as soon as you load the rifle and close the bolt. It is very dangerous. This is a big reason why with SKS rifles to check your bolt carefully, to insure the firing pin moves freely in the bolt before you reassemble the rifle if you detail stripped it, lest you not notice having accidently done this. I'm fairly certain doing it deliberately is illegal, but legal or not, it's a terrible idea. As for conversions that are both legal AND safe, I don't know of any. I thought you might want to know this though if you have a Chinese SKS, so that you don't get your wish at the range when you least expect it. :)

[mikescooling]

dam that sounds dangerous especially if you drooped it. kinda like a water sprinkler but with 7.62 x 39 rounds.

[Mnukedude]

As a matter of fact. I've heard that some people have (accidently) done exactly what I just described, and to immediately drop it has been a common reaction among this crowd;v . Some of them have gotten severely hurt this way. From what I've read, if this EVER happens to you, hold on for dear life and try to keep that sucker pointed down range any which way you can.;g

[mikescooling]

I am pretty sure I'm never going to the firing range again.
O my God.
And hay thanks this was probably the neatest thing I've read in a long time.

One of my Chinese SKSs that I bought for $80 each brand new fired full auto on me 2 times...I have no idea what happened but it scared the living ****e outta me and the rest of the range. I never made any adjustments to either gun. Someone told me that this wasn't all that uncommon, but I don't know of anyone else who this happened to.

I remember hearing that one shipment of SKS's that came in around 1990 was found to be 100% full auto. However, this wasn't[ discovered until they were sold and the new owners took 'em to the range.

The BATF attempted to round up all of the rifles from that shipment. However, they only were able to locate slightly less than 50%. I guess a lot of owners just "threw them out" because "they weren't working properly." ;f

Oh yeah, another thing that can cause an SKS to go cyclic(psycho?) on you is if the bolt is dirty on the inside. I mentioned before that you must pay attention with your chinese SKS to insure that the bolt assembly is reassembled CORRECTLY after detail stripping to avoid the full auto problem. Some may surmise that simply not detail stripping the bolt is the answer, figuring that if they don't disassemble it, they can't reassemble it wrong and thus avoid the problem. They are only half right. Carbon gets into the inside of the bolt assembly during firing, and especially in the case of SKS rifles that came packed in cosmoline or grease, this can mix together inside the bolt if the grease or cosmoline is not cleaned by detail stripping the bolt, and using a q-tip or pipecleaner to wipe out the inside. The mixture (if not cleaned out) can eventually jam the firing pin in place, and if it happens to be stuck in the forward position....well...you can imagine what happens next. An easy safety tip to use to prevent this from happening is to shake the bolt assembly after reassembling it. You should hear the firing pin rattle in the bolt. If it doesn't, most likely either the bolt is assembled wrong, or there is still excessive carbon in the bolt assembly. Clean it out. Lastly, for those living in fear of the SKS and owners who don't know how to detail strip the bolts, everything I've read seems to indicate that only chinese bolt assemblies can be misassembled to fire full auto.

I'm guessing mine was from the dirty gun side, not that I don't take care of my guns, but these things were packed in so much grease it took me 3 cleanings to get the majority of it out. I guess a little grease plus alot of carbon = a filthy gun and full auto...now if only i can get my other guns dirty enough to fire full auto...

[Zathras]

I've heard of this kind of thing before. A friend of mine had a Mac-10 that went full auto whenever it got too dirty, typically after he'd fired about three hundred rounds or so. He got nervous about owning it and returned it to the gun shop for a replacement, which worked properly.

[mikescooling]

So is a full auto just slam firing with the ability to stop UN like a jammed firing pin in the SKS?
DOS a full auto go complete in to battery then the pin drops or is it just slam firing?

[Mnukedude]

Now we're getting into territory I'm not totally sure of, so I hope what I say here is of value. I think it depends on which weapon you're talking about. In the case of the m-60, for example, the answer could well be that full auto firing is a perpetual slamfire situation, since this weapon fires from an open bolt position, from what I remember from my army days. The m-16 on the other hand, is another matter. It must go into battery to fire the cartridge (barring serious malfunction) because the firing pin's channel of movement on the business end is too long to allow the firing pin to protrude from the bolt face when the weapon is not locked. The bolt assembly turns inside the bolt carriage and retracts into the bolt carriage assembly as the bolt's locking lugs engage the barrel extension when the action is closing. Once the bolt is locked, the firing pin's channel of travel inside the bolt is short enough to allow the firing pin, if dealt a sharp blow (such as by the hammer)to contact the primer, but NOT before. This is a safety feature. I heard a story once of a fellow who had a cracked extractor on his AR-15 which broke as the rifle ejected a fired round. The chip from the extractor piece fell onto the bolt face as the action cycled and got pinned in place by the primer of the cartridge the cycling action had just picked up from the magazine. The round detonated as the action started to go into battery, bursting the shell all over the locking lugs, tearing off the case head, and blowing the remaining rounds in the magazine out through the floor plate. The operator was extremely lucky. Bottom line: the m-16 is not designed to allow the pin to drop until and unless the action is in battery, so in summary, how far removed from slam firing a full auto weapon is depends on which weapon you're asking about IMHO.

Every day I try to learn something new.
So This is a weeks worth.

It all depends on the gun. Submachine guns typically fire from an open bolt and basically slam fire. However rifles shoot a more powerful cartridge and have the danger of exploding if the primer is hit before the carrier is all the way home. Most automatic rifles have what is called an automatic sear. When you pull the trigger, it releases the hammer which is then caught by the automatic sear. When the bolt closes fully, it triggers the automatic sear, releasing the hammer after the bolt is all the way forward which prevents any chances of the hammer going forward to early.

Some semi-auto rifles such as the SKS have what is called a safety sear. It acts just like an automatic sear, but the weapon can only be fired in semi-auto.

excellent information, lonerunner. You explained it better than I did.:cool:

I was gonna ask, what prevents the hammer from just following the bolt on a weapon that has,say, a semi-FA selector? Is this true with all rifles?

[Menehune]

Yep, watch the firing pin on all guns. A few years ago, when I was new to 1911's, I was reassmebling a gun, and somehow put the wrong spring on he firing pin. It was too short, which allowed it to bounce around and the first time firing after words, it went full out on me. when the slide cycled forward, it let the pin fly forward into the primer. So ten rounds of .45 was gone in about a second. Csared the crap out of me.

Fortunatley, I was at at a freinds farm down in a sand pit when it happened. The last two rounds were at the top of the berm.

I understand about that,I'm not understanding how the bolt triggers the auto sear and what happens in a semi fire-auto fire selector situation.

So whats to stop this exact nightmare from happening more often than not to Lightning link users. Especially since most if not all AR15's that achieve full-auto(via LL), were never meant to function how the Lightning link makes the gun function. ??????
