>Barrel length
What exactly does it affect
velocity and handling
>Barrel twist
is for optimization in regards to ammo but isnt that important. if its not an ar you dont get a fucking choice for twist rate. the twist rate a gun comes with is what it comes with.
>Short and long stroke piston
different ways of pushing the bolt back
>Di or piston gas systems
if this is an ar di pistons is a bastardized retrrofit. if its an ak or something its piston. you just stick with the system the gun was designed for.
>Adjustable gas systems
there so you can make you gun run with weak or hot ammo not that important if your gun was manufactured right to begin with and you are shooting factory ammo.
>Trigger weight
should be self explanatory. you dont need a light trigger to shoot well but it does help. its more about personal skill than anything.

>>33226075
>barrel length
Longer barrels will increase the velocity of a round (up to a certain point, depends on cartridge). Although shorter barrels are more maneuverable and weigh less. Longer barrels will generally also have a longer sight radius (distance between sights) so you will be able to shoot more accurately, even if barrel length doesn't really affect accuracy.
>barrel twist
It's how long a bullet takes to make a complete turn while in the barrel. A 1:9 twist will make a complete turn every 9 inches. Different cartridges and bullet weights will need different twist rates to be optimal.
>short and long stroke piston
Different, but similar methods of cycling a gas operated gun. I'm not the most familiar with them but the long stroke piston is directly attached to the bolt carrier and moves the full length, while a short stroke piston isnt. Look at the difference between an ak47 (long) and sks (short).
>direct impingement (di) and piston
Piston gas systems use the expanding gasses taken from the barrel to move a piston and bolt carrier group to cycle a gun. Di just skips the piston and slams gas into the bolt carrier. An ar isn't exactly di, but close enough to understand the basics.
>adjustable gas
Let's you regulate how much gas the gun uses to cycle. For different pressure rounds or if you're using a suppressor.
>trigger weight
How much weight it takes to pull the trigger.

Well fuck, I didn't see that you already responded.

>>33226182
I see, are there any other basic things about firearms I should know? I mean I'm picking it up here and there but I'd rather be sure before I go and make a fool of myself.

>>33226201
Figure out what gun you're interested in and do as much research on it as you want. I've never read the sticky, but people usually recommend that. Most stuff you will just pick up on as you go along. Always ask questions, and if you find yourself hooked, welcome to the ride. You can't ever get off.

>I see, are there any other basic things about firearms I should know?
It really isn't rocket science. Modern firearms pretty much all do the same, with slightly different operating system design. There's some bad apples in every basket, and traits you better know about in specific guns (ie. keep the AR lubed, AK just clean).

Besides that, all I can think of would be hammering down the safe weapon handling rules in your skull:
Keep your fingers off the trigger, muzzle pointed downwards and away from important things (ie feet), and double clear gun's chamber once you detach the magazine.

Fuck you

>>33226411
Yeah thankfully coming from the UK firearm safety was hate fucked into my skull before you even got withing 100m of a real weapon.

There are 4 main gun rules:

1. Guns are sometimes loaded.
2. Point the gun anywhere you choose.
3. Put your finger on the trigger while pointing the gun anywhere.
4. Shoot at any target you see, or don't see.

Paste and crayons make a great substitute for MREs

Fellow bong here.

Firearm safety isn't drilled into people at all, only fear.

People are scared to death of them but if they pick them up the first thing the mongo will do is try to pick their nose with the finger on the trigg

>>33226506
Well I got the chance to do cadets in the UK when I was younger. My unit at least drilled firearm safety as the number one rule. Reason being is if you fuck up then no more guns for the unit which nobody wanted, so we had to be shit hot on every single thing we did.

>>33226075

Damn I have a great copy and paste for this on my computer at home, a summary would be

>learn to clean your guns, you have to do the exterior most often
>never touch or lean your barrel on anything to fire as it changes your point of impact
>more important than using a safety, keep your fingers out of the trigger guard until it's time to shoot and always always always watch where the end of the barely is pointed unless the gun is disassembled
>if you don't research the proper forms, you will never get good. For automatic pistols you must get good at the thumbs forward grip using either the Weaver or isoceles stance
>The best starter gun is a 22 lr bolt action from any good brand name. You'll never sell it, it's very intuitive and easy to get good at, won't develop a flinch, ammo at Walmart, great for small game, and it's safer to shoot at most places than a larger round

I know others have responded, but this is fun to explain anyway, so…

>Barrel length - What exactly does it affect?

3 things: velocity of the bullet, accuracy of the bullet, and the physical properties of the gun itself (length, weight, balance)

Longer barrel:
>larger distance for explosion to accelerate bullet – faster velocity as bullet exits the barrel
>longer distance for the round to be “directed” along the path of the gun’s aim – greater accuracy
>Heavier, bulkier gun

Shorter barrel:
>lower velocity on round
>less accuracy
>lighter, shorter gun

>Barrel twist - Does this stabilize the round?
Yes, same principle in throwing an (American) Football – give it a spiral twist, and it keeps the trajectory straighter.
This technique is called “rifling”, and it was arguably the biggest technological advancement in terms of accuracy of the last 300 years.

>Trigger weight
The amount of force needed to pull the trigger. The harder you have to pull, the more you shake. Therefore, lighter triggers are more desirable.
Lighter trigger = more sensitive = greater accuracy

Are you familiar with the difference between automatic handguns and revolvers?

Have fun in the US!

>>33228065
length of barrel being a major factor in accuracy is a total myth, provided that the barrel hasn't just been lopped off or you're using a barrel a firearm was designed to use.

>>33226075
Watch out the wild niggers m8

>>33228084
It IS kind of important in accuracy, but not mechanical accuracy. If you had the gun in a vice grip aimed by a computer, length of the barrel won't affect the accuracy of the gun really at all. But if you're aiming the gun yourself, a longer barrel provides a longer sight radius.

Basically the gun is just as accurate no matter how long the barrel is, but YOU are more accurate with a longer barrel.

Welcome to burgerland, any chance you're in CO area? I used to live in Aberdeen and would love to bring a bong shooting

1. 1. Treat every gun as if it was loaded until you have personally (safely) confirmed it is not.

2. Until you’ve done step 1, don’t point the gun at anything you don’t want dead/destroyed. Be aware that bullets can go through things.

3. Never, ever, handle someone else’s gun without their permission. Ownership is sacred in gun culture. This also applies to you and your guns, if/when you get your own. You have a right to be possessive and protective of them.

4. Be inquisitive, but humble. No one minds if you ask questions (most people really enjoy getting the opportunity to teach) but don’t attempt to show off your limited knowledge. If you’re new, it will show.

5. Guns are absurdly loud. It’s hard to fathom just how loud until you actually stand next to them. Always wear ear protection when shooting indoors. Open-air outdoor shooting could go either way, but it’s better to err on the side of caution.

6. As long as you’re being safe, have fun.

>>33228084
True, but I didn't say "major factor". I was explaining theory. And an AR with a 24" Barrel is definitely going to be more accurate than this thing:
