Anyone know where i can get a 20" upper with a 1:9 twist from a company that isnt hot garbage? Posted on July 23, 2022 by PrepHole Contributor Anyone know where i can get a 20" upper with a 1:9 twist from a company that isnt hot garbage?
Why not make your own?
>isnt hot garbage
Every source ive seen says 1:9 is great for 55gr to 62gr. Thats the most common ammo available.
Twist rates are a meme.
>great for budget military reject plinking ammo
Most people care more about getting maximum performance from their heavy grain high quality ammo.
Dude most people shoot 55gr Tula at garbage twice a year. Get out of your basement.
>Dude most people shoot 55gr Tula at garbage twice a year.
Those aren't people and twist rate doesn't matter to them anyway.
>If you don't have at least one upper capable of using cheap ammo to the fullest you're larping.
Jokes on you gay, I am larping but I still have a Daniel Defense somewhere with a 1:8 barrel in it.
oh fuck dude, you just destroyed me. I'm gonna go cry now.
is that before or after you shoot up your local school? DD is the incel brand
Nah, you can chill out now. Just double checked and it's 1:7 too.
Guess I don't own any poorfag barrels, sorry.
Im considering switching priorities to a 1:7 twist, and getting a BCM or Aero. Would a 1:7 twist run 55gr and 62gr okay?
>Would a 1:7 twist run 55gr and 62gr okay?
honestly just how much are you looking to spend on this?
Ive gotta budget of 1700 dollars.
For just the upper? Forget BCM and Aero.
Criterion 20" chrome lined barrel
Slap that in whatever you're building and it will be the best. The rest doesn't matter.
Most people don't have the knowledge or wherewithal to assemble an upper from a stripped barrel, anon.
>most people are physically incapable of turning a wrench in the correct direction
Yes, you're right.
depends if you have to pin the FSB
that's really hard to do properly
if it's already installed and pinned yeah obviously it's just legos at that point
Best compromise is to buy an F-marked FSB pinned to the barrel already, and then put in the gas tube/delta ring/everything else yourself
>or go low profile like a fag
> you can chill out now
go fuck yourself this isn't reddit, this is not your safe space.
>this isn't reddit
Are you sure? You seem lost.
>imagine not having multiple uppers built for different purposes
If you don't have at least one upper capable of using cheap ammo to the fullest you're larping.
Just build one dude.
Well i dont mind building one at all, its just i cant find a barrel thats made by a reputable source
What a fuckin retard you are
didn't you already ask this?
no sir, this is the first thread ive made on this.
Del-ton and other budget civilian garbage-tier manufacturers are the only place you're going to find sub-standard civilian bullshit like 1:9 twists, duh.
If you ask for trash, the answer is in the dumpster. Don't be shocked.
What twist would you recommend?
I only worry about not having a twist for common ammunition, because in the event that I need ammo, and cant just go out and buy it, I dont want to be stuck scavenging for more rare ammo like 77gr.
There is no accuracy penalty for shooting 55gr out of 1:7 vs 1:9
You would need a bench rest and a micrometer to detect any difference at all.
Charts like this are misleading
You can shoot 69gr sierras out of a 1:9
ok, buy a stripped upper, buy a barrel, buy a bolt and buy a handguard and assemble it, why the fuck do you want a complete upper if nothing meets your criteria?
i cant even find a barrel made by a reputable source either. Im completely fine with building my own upper.
build it. will be better and end up cheaper. also you will just end up with what you like and not having to buy bs later. heres a twist chart
sweetie it's time for your daily 20" AR thread!
I want to build that with the LMT flare gun mount but fuck it’s so expensive
see if you can find the old cobray 37mm launchers. theyre literally just m203's
Try Doublestar? They make pretty decent quality stuff, but aren't cheap.
I dont mind if its not cheap. Ive gotta pretty good budget.
They've got em then anon.
Everything I've bought from them has been great.
You're not going to win any gucci contests but your shit will 100% do what it says on the tin.
Windham Weaponry. Bushmaster was a Daniel Defense-tier AR maker back in the day. Before they moved. I have one made in 1996 and everything new I've bought has been a letdown.
If you can find one.
Theyre out of stock
Aero had 20 inch uppers on sale on and off for the last month but idk about the twist etc
How often do they get new stock in? I've been on their waiting list for two weeks. Should I give up and get a Del Ton?
They have one in stock right now, ive got it open on a separate tab. here
Meh, I'm sorry. I'm going to be mounting a 4x scope on mine and I wanted the flattop.
That's the main pain in the ass, yes. Then you need a torque wrench and so forth. It's impossible IMHO to fuck up on a lower, and can do it with tools you have lying around the garage. The same is emphatically not true for assembling an upper using a stripped barrel -- dimpling the barrel for the set screws on the gas block, etc. -- and newfags need to be aware of that. I am not shitposting. I am trying to help.
I mean you could remove the carry handle, its not fixed.
>A2 Detachable Carry Handle
Well fuck me for not reading the fine print. Thanks anon.
No prob dude, i think im about to pick one up too
>Then you need a torque wrench and so forth
no you don't, torque spec is 30 to 80 lbs, the reason for the wide range is that you need to index the barrel nut so the gas tube slips through one of the grooves
there is no need for a torque wrench, just tighten the barrel nut until the holes line up and install your gas tube
if you can't tell what 30-80ft lb feels like, you should just stop doing anything related to anything mechanical or gun
God damn it, most DON'T. Nor do they have drill presses to correctly prep the barrel to install a non-shitty gas block. It is not within easy reach of your average postmodern American, mechanically or skillwise. Putting together a lower is like building a plastic model of a battleship, except with springs and pins and shit. Building an upper off a stripped barrel is not and you know it and newfags need to know this so they won't waste their money.
That's all I'm going to beat the topic for.
>Building an upper off a stripped barrel is not and you know it and newfags need to know this so they won't waste their money.
yeah i fucked up the first 2 times i tried to pin a barrel myself
it's tricky for sure, you need an undrilled front sight or an end mill and lots of skill and patience, and of course a taper reamer
How much experience did you have fitting gun parts and making things in general before that? I'm currently tempted by two uppers, one new and yet to be available, but neither come with barrels. However, with no taper reamer, no usable drill press, and only hand tools (of course also things like electric hand drills), I suppose I should just wait for the complete gun to be sold and throw surplus furniture on it, and in the meantime, buy a little surplus here and there. On the other hand, knowing how to put together an upper isn't a bad skill to have. I just worry about canting my sight like a retard.
1:9 twist barrel or A1/A2 threads? Because the A1/A2 threads are probably from the lack of new available 20" barrels and especially new carry handle uppers available. The used market is fucked on those.
>How much experience did you have fitting gun parts and making things in general before that?
not very that was a while ago but it's still hard
if you had an undrilled FSP it's not hard, if you have a FSP that's already drilled, i would say don't even bother honestly
1:8 is better for most types of ammo
Why are there so many of these threads every day now?
bro like how does rifling even spin the bullet if the rifling disappear when it exists the barrel
Fun fact. Grains are not what determines what length of twist you need to stabilize a projectile. It's the length of the bullet. Now those are usually directly correlated, but not always. Which is why you can fire a very light solid copper projectile and not have it overstabilized because its dimensions are the same. Or conversely, you might make an incredibly heavy DU bullet, but not need to have a tighter twist ratio because the bullets relatively short.
Why in the hell would you want a 1:9 instead of 1:7?
Fulton Armory has some nice 20" uppers with criterion barrels.
For a cool grand, yes.
