Are short barrel AR-15s worth a damn?
>>29486614
In terms of accuracy and such? Yeah they are still okay. Don't buy into the "IT'S 20" OR NOTHIN" bullshit. Sure, a longer barrel will have greater velocity, offset recoil/muzzle rise, and allow for more accurate sight alignment, but there are advantages to short AR's too.
Less weight, handier in close quarters, and they look cool.
>>29486614
Yes. Very handy when taking it inside an elementary school.
>>29486614
No AR-15 is worth a damn.
>>29486642
>less weight
hardly
>handier in close quarters
marginally
>look cool
Shit taste
20" AR is the only AR
>>29486614

How often would a civie need such

no
looks fucking dumb as shit

In calibers that aren't .223

Properly set up, with a trained user, the AR is useable out to 500m with short barrels (11.5" in this video)
Yes, you do lose muzzle velocity, but at the close quarters you'd normally want to employ it, it is a non-issue.

Am I stupid for wanting this upper? Because I want this upper
>>29486614
The look cooler :3
Personally, I think its better to move to a bullpup if you want the shorter OAL or to the 300blk
>>29486614
If you're room clearing or operating in close quarters, yes, they're the best there is
Otherwise no, they're not worth using at all other than a fun range toy
>>29487588
Here's the (you) now get out
>>29488217
>How often would a civie need such
Considering your civie would be potentially using it in their home, or transporting it to/from whatever range why the fuck not. You wouldn't think shit about it if it weren't a NFA item that set arbitrary limits on barrel lengths.
What about a short barrel AR 10?
I believe 10 inches in the minimum you want in a 5.56 AR.
They made a specific load for that barrel length forgot what it was named. Think it was for afghan?
>>29486614
Best length to worst length
20"
14.5"
16"
12.5"
11.5"
10.3/10.5"
>>29490065
eeeeeeeeeeeeeeEEEEEEEEEEeeeeeeeEEEEEE
All of this buttfrustration at 10.3 inch barrels.
A MK18 (10.3 inch barreled AR) is an assaulter's weapon. It's best at 300m and under. In urban environments, engagements take place at stupid close distances. Weight, maneuverability and pointability are excellent with short barreled AR's. There is a reason that assaulter's use them.
Now that being said for a more rounded weapon a 14.5 or 16 inch barrel would be ideal.
>>29490097
>14.5" > 16"
But what fucking logic?
The only short AR worth shit is the 733.
>>29490416
m321 is best
>>29488357
Would get something without the fixed front sight so as to allow better optic use, but other than that it looks good.
>>29487597
I'm not sure if this is bait or not but a 20" M16A4 is a lot shittier than a 10.3" Mk18, not "marginally worse".
>>29490097
I have a 7.5" AR and no one can stop me from having fun.
>>29490367
This list has no clear logic but to answer your question, many people find the 14.5 more asethically pleasing than the 16", with the loss in velocity negligible. Some might go as far to say that the extra inch you save makes it prefered to a 16" in cqc (I don't buy this). There's nothing really wrong with a 14.5, with exception being having to pin and weld your MD, which can make changing MD's and rails and GB's more complicated. That's why I'd prefer the 16"
>>29488307
Don't get me wrong, I love the AR, and I love .223, but the caliber is objectively abysmal in a sub 16" barrel.
The same applies to the fabled slav 5.45, Soviet/Russian troops dig the AKs-74, good range and power, low recoil, but the armed forces and special units neglected the AKs-74u, because the range and power was dogshit (though everyone who shot it agreed it was very fun, even Mikhail Kalashnikov, who didn't like 5.45), nobody who was doing frontline combat would use it by choice, more often than not, it was assigned to tankers and pilots.
Speed based rounds are objectively bad performers in too short barrels.
>>29490152
>Weight, maneuverability and pointability are excellent with short barreled AR's.
Yes but how are ballistics?
The Mk.18 would be perfect in .300BLK
>>29490784
>7.5"
absolute madman
fact: if you fire 300 out of a sub 12 inch barrel you'll get the same trajectory as a 223 or 556 out of a 20 inch barrel.
>>29490784
i have a four inch AR and i want someone to stop me.

>>29490654
Good luck not shooting yourself in the head.
>>29491497
i just wish i could get a bolt with a side charging handle for the convenience, but that tube needs a proprietary one. i wonder if i could buy the upper and ask them to put the handle for me.
>>29486614
we talking 14.5" or 10.5" ?
Because the M4 does just fine with 14.6" or so barrel
If you aren't a 1337 oper8r then it doesn't matter what length your ar is. Its still gonna go bang when you pull the trigger and make holes in stuff.
>>29491424
Does the ability of the rounds fragmentation diminish and potentially stop altogether with shorter barrels? Sure, that's not the only mechanic it has. It's not like the bullet turns into a needle that does nothing after it drops below 2700 fps. It will still enter you, it can definitely still yaw, it can definitely still kill you. A 20 inch AR is going to give you maybe, MAYBE, 50-75 meters extra fragmentation range, that's it, and again, it's not the only feature that kills you.
>>29491613
not if you get a varmint grenade round.
>>29491613
bullet construction also has a lot to do with fragmentation. some loads are great for SBR's
>>29491648
Fair points. Which rounds specifically?
>>29491638
I question the effectiveness but have no evidence for or against it, do you?
>>29491522
britbong LanTac made side charging AR for you.
>>29488217
What would a civilian "need" an AR for but close quarters? You could take an AR with a longer barrel out varmint hunting, but for home defense there's not really any downside to the shorter barrel.
>>29491707
on that bolt?

>>29491648
>some loads are great for SBR
Great is an overstatement. There are rounds, mostly soft points, that perform less miserably when compared to their full-velocity performance. In practical terms, I mean the 11"-13" ARs are never going to produce an equivalent terminal effect until the target is within 75 or so yards.
That being said, I also think the dependency on yaw/fragmentation to produce a killing wound at distance isn't practical for Average Joe. Civilians should be less concerned about a "do everything" carbine and more concerned about being knowledgeable about what tool is right for what job. That includes using full-size and magnum rifle cartridges when long-range precision is desired.
>>29491522
ASA makes 9mm side chargers and only charge $25 to make the cut in your bolt
>>29491449
So?
Both that one don't trust you, just want to be able to point to something besides the screenshot of this post
>>29486614
In 5.56?
No.
>>29492052
when you say cut do you mean they'll frame cylinder handle on my own bolt?
>>29491516
And?
>>29491519
It literally screws into the side of the vehicle. How would you shoot yourself with that?
>>29492320
nevermind found something dank, although i feel my inner autism flaring from having to do such a workaround approach while using my own bolt.
>>29488217
>need
There's that word again. Why do you "need" anything? I don't "need" a short barrel, I "want" a short barrel. Why? Because I can have one. :^)
Eat shit bootlicker.

20 inch barrels should be the minimum. The Marines have been using them for fucking years in cq raids and stuff in the mid east with no problem.
I don't fuck with short shit. If I am so confined that I cant wield a full size barrel then switching to my fullsize pistol would be the next logical.
Train ur weapon transitions. Stop worrying.
>>29492656
>>use to shoot out to 10mm
damn bro, what optics you use for that?
>>29492674
God damn it. I just got a new phone and it keeps auto correcting for no fucking reason. Really starting to piss me off. Fuck you samsung! POS.
I meant to say 100m.

>>29492669
You do realize that the Marines officially adopted the M4A1 as their standard service rifle to replace the M16A4, right?
Also, you've obviously never been a crew member on any kind of vehicle track or otherwise. And you obviously don't realize that 99% of ground troops don't have a sidearm.
With that said, I do believe they should keep the M16A4 and repurpose the M16A2's still in stock for DMR use for fire team level. Give your rifleman the DMR'd M16 while your Grenadier uses a M4, same with your TL.
>>29493037
I know they replaced it now, yes. But I don't think they were complaining.
No sidearms? lol nah i didnt know but i can believe it since ive heard alot of ground troops dont even have earpro

The only time a civie will need an AR is in three situations
>Home Defense
You'd want a short gun
>Going to the range
A short AR fits in bags a lot more discreetly and is less likely to notify your neighbors and the local nigs (or nigs scouting the cracka town) if you have guns
>Tyranny
Asymmetrical warfare is about concealing guns and getting into the belly of the beast before deploying them, not marching right through the front door wearing multicam, team wendy helmets, and carrying an M1A with twenty other guys behind you. a 10.5" AR fits very well under a non-edgelord but useful coat like an M65 field jacket or in a normal backpack.
These three instances are all over the spectrum in likelihood but all of them are pretty well suited to an SBR of any kind, not just ARs.

I used one of those LMT MK18 uppers (10.5") on a build a few years back.
It was kind of neat because it came with a tag and a nato stock number (NSN). It made it feel milspec even though it's just another upper. Very good barrel though.
>>29494163
thats not a 10.5 thats an 11or 12 with carbine gas and a fake fsb
its a mock dissapator based on a midlength handguard instead of a a rifle handguard
the only benefit is extra weight
