I understand. To be fair one can field strip an M/AR with nothing more than finger power or a round of ammo.

Practice, practice, practice.
Nonsense. Try this this link for advice from a ballistician:
Understanding Twist: Bullet Stabilization
The reason the military settled on a 1:7 twist is to stabilize the M856 tracer. It's about the same length as a 80 grain BTHP.
False.
That’s the over-all best summary I’ve seen in a long time (thanks for posting ;^)! Two things mentioned that a lot of folks forget: KISS Principle & weight. You probably don’t need a rifle with ‘after-market everything’, plus 5 feet of rail (and some gadget attached to every available location). And your rifle doesn’t have to (& shouldn’t?) weigh as much as grandad’s M1 Garand...
Obviously your so called ballistician hasn’t seen a 55 grain pill moving at 4000 fps go up in a cloud of gray dust trying to push it down a 1-7 twist. I’ve seen them shear the jackets off!
lol..not fair! He was powered by Sprite! ;-)
One question worth asking in life: "What will get you killed?" As a friend who's an engineer tells me, there are different kinds of knowledge. There's "what you know that you know", which is often based on proven science & engineering, decades of experience, etc. Solid knowledge generally won't get you killed. Then there's "what you know that you don't know" - if you run into that, you'll probably be OK too, because you can often work around it. But my friend says to watch out for something else: "what you don't know that you don't know". It's that last one that'll kill you.
I imagine everyone in that training class (possibly even the instructors) learned a few things that they didn't know that they didn't know...
;^)
Thanks for the post, good enough to follow.
That’s funny! I missed that. lol The best I have done with mine was about 30 seconds. Dropping the trigger group can hang up a little. But that might have been the MGD slowing me down, obviously faster on Sprite. lol
I’ve been wanting to get an ACOG for my single shot rifled slug shotgun.
Problem is the darn things cost more than the gun!
I was on the receiving end of a young VC gal using a Chinese built SKS.
I did, however, put three 7.62 rounds from my M14 into her.
When it got quiet, we went to check out the damage. This young lady (probably 21 to 24 yo) was down but not dead. I took the SKS from her hand, got the bleeding under control and got her a helicopter ride to the hospital. I even saw her at the women’s POW cam about 5 or 6 weeks later. She thanked me for saving her life and not finishing her off.
The SKS she had could fire fully auto, but why? It had a 5 round built-in magazine and was not replaceable. It needed reloading through the breach after every 5 shots.
What Nut'n Fancy calls the philosophy of use plays a part. It's a civilian firearm. It's great to envision sub-MOA accuracy out to 500 meters but if you're shooting people at 500 meters you may find that self-defense plea to be a little tough. You're not in the military, or if you're a vet, you're not in the military anymore. In any case, if you do find yourself engaged in long-range people-hunting you've probably got time to break out a more specialty gun. And a spotter. Just my $0.02.
The bullet failure you described is not a matter of stability. It's also not something to worry about in an AR-15 platform.
Great story and welcome home. Only one quibble: the built-in mag on an SKS carries 10 rounds. Still have one ex-VC SKS. There was a select-fire Chinese version of the SKS that had a detachable 30 round magazine - saw one in a gun shop in Norfolk once - the owner didn’t know it was a machine gun!
I shot a guy in the hand once and patched him up - and he helped carry me to my medevac bird about an hour later.
About 20 years ago, I was the Vice President of Trijicon. I had a big part in getting the RCO into the Marine Corps.
“and that’s Trijicon’s engineering marvel, the Advanced Combat Optical Gunsight (ACOG).”
$1,200 a copy. We have 2 “family” AR rifles. That’s $2,400 plus tax. Can’t afford it. Wish we could, but we can’t.
Went with the Aimpoint red dots. Can’t hit much past 350-400 reliably with my late 50s eyes. But for shots longer than that I use a bolt action.
My only quibble with this article so far.
L
Chainmail,
It might have been a 10 round mag. I only had possession of it for about 2 hours while we walked out of the bush. That was 50 years ago, my memory’s not was it once was. What I was most amazed at was that the magazine was not detachable and had to be reloaded while attached to the gun.

Understand. I am even more ancient!
An SKS can also be loaded by flipping it over, popping mag catch open, and dumping loose rounds point forward, then slapping the mag base closed.
I used to play with my captured SKS a lot.
