Free float vs standard

Don't expect nu-Jow Forums to understand freefloat aspects beyond
>MAKE YUR GUN MOAR ACCURATE

once you buy your first gun you'll see it first hand

The secret to AR accuracy:
>use a low-profile gas-block and the longest float tube you can get
>mount a front sight to the freefloat tube
>sling-tension that motherfucker up good

Op here, I have several guns and my AR handguard is FF, I just wanted to hear the opinions of others.

Torques the tube too much, railed gas block is better

Placing sights on the rail and bracing said rail removes the advantages of a free-float rail. The ideal solution is to place sights on the barrel and on the rear of the receiver, such as with gas block sights or the Ultradyne C4 sights. Or join the 21st century and use an electronic sight and get none of the drawbacks of using sights on a rail and tons of advantages.

Poe's law. It's real.

lol wut?

You want your sight to stay in the same place and not add unsprung weight to the barrel. Consistancy is accuracy. That's where the free float helps, as it allows the barrel to warp the same way with each shot (minus thermal expansion, but that's with all barrels) The only part that effects the barrel's movement is the gasblock and upper receiver at that point

If you get an optic your free float should only be as long as your grip +1-2 inches for mounting a flashlight up front, if you plan on using it as a defense/duty weapon. Especially if you are using an optic that is rugged and has a reticle that is still there without illumination

A small amount of weight on the gas block will retain consistency albeit a different one than without said added weight. If you're bracing off the sling that force is going to cause the handguard to move which also moves the front sight post leading to a far more inconsistent sight alignment.

Using an optic is a separate issue from having back up irons, unless you plan on getting a chinweld with an rmr attached to an acog

Who the fuck braces the sling off the front unless using a triangle frontpost?

Just in front of the receiver and just behind the receiver gives the best movement and support combo.

It's not a seperate issue, but completely related. If you are using a LVPO especially a FFP one you don't need BUIS because even if the illumination fails the etched reticle is still there, requires less alignment and has the ability to magnify unlike irons.

And don't give me that tritium bullshit. If you are illuminating your target so you know what you are shooting the etched reticle will work.

That being said I have BUIS on my because well, i have nothing else to throw them on and they already match the rail.

There's no reason not too, since pretty much every non-chinkshit handguard is free floated these days.

>hurdur it's more accurate
The damn guard is still attached to the rifle. It's a piece of fucking metal, that is all connected. No amount of handshake or lack there off is going to make the barrel move anymore or anyless than it would normally.

Most engagements are withing 50 meters so it doesn't matter.

MOA is mostly marketing as far as ARs are concerned. You're not building a distance competition gun are you?

The force of bracing the sling all ends up being applied to the handguard unless it's attached to the gas block, in which case why not have a rgb mounted sight for the longer sight picture?

It's a separate issue because buis are a matter of if the primary sight fails for whatever reason, whether the loss of illumination or damage leaving it inoperable. You don't leave a spare at home because you bought the best tires on the market.

Are you fucking retarded?

Are you? What he said is 100% correct a free float isn't going to make a difference due to your handshaking.

This nigger is correct.
BUIS should be standard on any rifle you have deemed the one you'd grab if shit went down.
If it's a range toy and nothing else BUIS are not necessary

Having the front sight fixed directly to the barrel is always more consistent than having it on an unrelated surface. Especially when it's on a long, unsupported aluminum tube that flexes independently of the barrel. Any shift in the bore axis will theoretically have the front sight follow with it.

But irons don't matter anymore and you don't shoot anything but two inch groups at 100 yards.

It matters when you have the rifle resting on or pressed against something like a barricade or bipod.

You fucking idiot, have you ever seen how much POI shifts at even just 100 yards if you have the far-end of your handguard resting on something after you zeroed it with the middle part resting?

It does not.

The floating rifle meme has nothing to do with how your hands rest on it. It's purely about vibrations throughout the barrel upon firing. There is zero fucking effect your hands will have between a floating and none-floating. fucking idiots.

Riiight. You know more than every gun designer and engineer ever. Did your uncle who was in the military teach you that?

>know more than any gun designer
IF you notice all the actual military weapons don't have it. Weird, wonder why civilians have all of this extra flashy shit. Oh right, rice. Shit that doesn't actually add performance just flare.

Nice appeal to authority kid. Free floated hand guards also don't interfere with the barrel vibrating when firing, this squeezes a bit more accuracy out of the gun. Also what a fucking waste of dubs.

You're a waste of air as you couldn't even be assed to see that vibrations were already covered.

But yea, enjoy your .1 MOA gain at 1000 yards.

I am referring to using irons. If you use irons mounted to a free-float rail, your POI will remain exactly the same, but if you bear down on that rail, your POA will shift as the rail will flex and it will throw off your aim. This is not an issue with an electrooptic since it is placed on the receiver which generally doesn't experience much stress when placed on a barricade, sandbag, etc.. If, however, your irons are mounted on the barrel like in the case of the Ultradyne C4s or are integrated into the gas block like PRI, you'll get all the benefits of using a free-float rail and none of the downsides when it comes to iron sight usage.

I trust my Aimpoints to overcome significantly more abuse than my irons.

it shouldn't be possible to be this much of a brainlet

FF is great for range and competition. For combat its irrelevant, which is to say that if two otherwise equal forces faced off with one side carrying regular M4s and the other FF'd M4s, it would have zero impact on the outcome of the engagement. Its definitely the future, but its also one of those meaningless incremental improvements rather than the major boon its often touted as, since you done see any difference outside of a bench.

Not a single person here fires their rifle enough to benefit of reduced droop on the barrel.

Faggots who use it are like people who have slotted/drilled rotors on daily cars.

This, my group can shift as much as 3 MOA @ 100y with my A1 build depending on which part of the milspec triangle handguard is resting on my benchrest. The same happens to my RPK; if I shoot from the barrel-mounted bipod, bullets go where I'm aiming because that's how I zeroed it. If I shoot from the handguard, suddenly the group is quite a bit lower. That's because of grade school physics.

Meanwhile, my 14.5 middy with a freefloated Centurion rail has no shift no matter how I use the rail. A braindead chimp should comprehend this shit.
lmao fucking dumb nigger

Yea, because the military always get the absolute best of everything

Military ARs also still largely use government profile barrels, so...actually, you clearly have no clue about barrel harmonics if this thread is any indication, so that point will just go over your head.

>freefloated Centurion rail

How do you like those? Trying to decide between that, a KAC rail, and a Midwest Industries 2-piece for my M4gery. Any other options out there that'll fit on without having to remove my gas block?

>buying an AR
Might as well suck a fat pile of shit off an AIDS dick while you’re at it

I've had all three of those, plus a RIS II, and I think the Centurion C4 is easily superior.

That barrel still come out to 16" with the flash hider?

Actually, let me rephrase that; the RIS II can be used to bludgeon a Bradley into spare parts and still be securely mounted to the barrel, so it's perfect for military use. Holy shit with dat weight tho.

Hahaha fuck no, like 12.5".

>Holy shit with dat weight tho.

It was designed with the intention of being able to handle the recoil of an M203, so that's somewhat understandable.

Mine's not an SBR build. Got a plain Jane 16" barrel on it.

Yeah but I had it paired with a SOCOM profile barrel and everything north of the chamber was dummy thicc. Eventually went from a Block 2 build to an M4A1 build by swapping it out with a KAC RAS. Much happier with that.

Getting free float now costs almost nothing over a "standard" handguard. There's basically no reason unless you're a megapoorfag to not have fre float.

Still go C4.

What's the deal with the mag release

12 inch or 7.25? Is the extra railspace beyond the front sight worth the extra pound if I've got a 16" barrel?

Just go 7, FSB cutout on anything not a RIS II is big ghey.
It's a mag release.

My budget ass ar came with a free float handguard. And a M16 cut bcg. And .223 wylde barrel.

Are you not aware that the US military is undergoing trials of freeflpat tubes and possible the only reason they haven’t been adopted is due to the fact that they can shift the front post by a greater degree of the rifle is dropped?

>talking shit about people buying ARs
>still hasn’t bought a gun of his own

Yo

Why not both? I have 2 ARs in both FF and standard. Free float looks cooler, but I cant mount my bayonet to that ;^)

>not having a free floated handguard AND a FSB gas block

>slotted/drilled rotors

In most cases, it will have almost zero effect. If you are shooting with a match barrel, a match trigger, and a quality optic, and you are also a top-level shooter, it will have a slight effect on accuracy.

I've found as long as you aren't loading the handguard, and hence the barrel, you are having almost no effect on barrel harmonics and thus bullet impact.

Bamp

>tripfag built his A1 wrong
Unsurprising

>anons don't know how pressure against a barrel can impact POI
Unsurprising. :^

Fuck you undertale faggot

This user has the right idea

This. I haven't shot my RPK from the shoulder enough, but same concept applies. As an interesting sidenote, the Colt 611, 741, 941 series (HBAR 20" with M60 bipod), basically a US RPK, are regarded as a failed project, while the RPK is lauded worldwide.

>he built his AR wrong so a bit of pressure shifts the POI that much
Please go back to redd.it

I only see the free float vs non free float handguard thing with ARs.
Is it something that doesn't affect other rifles, like AKs, 550s and whatever? Or could those rilf es also benefit from having a free float handguard?

Not really sure if the concept has been investigated on any other pattern of rifle. The AK isn’t really conducive to a FF because of the way the handguard, barrel, and gas system. It may have been done, I’ve just never heard of it. As far as other rifles go, I don’t think any other have been done because there’s not much of a market for SCAR customization because not many people have them. Ultimately I don’t think a FF is absolutely necessary but it is the most modern development as handguard a are concerned.

And when I refer to the SCAR I am not saying ONLY the SCAR, I mean any non AK/AR pattern rifle that does not occupy a large portion of the marketshare

AKs supposedly dont gain much from free floating, something to do with how violent the action is. Pretty sure there are FF hand guards out there regardless.
FALs have a few FF options
G3s are already FF'd by design
SCARs, 416s and most other modern (that's to say, came to the market in the last 20 years) rifles are as well.
