I'm looking to build a basic bitch 14.5" upper. Based on the pricing of my local dealers it will be about $200 more for a mid-length vs carbine length gas system.
>Is mid-length worth the additional dollarydoos?
Don't I feel silly, asking a weapon related question on /k/. I guess next time I should shill for my favourite waifu instead.
I should be at the range mourning Scalia
You said basic bitch, so don't worry about it.
If you go midlength you'll have less recoil, slower bolt speed, longer bolt lug life, and a few other things. If it's just for cheap blasting and your life won't depend on it for thousands of rounds, don't worry about it.
I personally like the look of the midlength and the slightly longer handguard options. I've been told they're a little better in terms of parts wear and a little softer shooting but I don't know how noticeable that would be until you get into 18-20 inch rifle uppers.
Mid length seems ok but I'm not sure its really worth the trouble.
Unless your AR is going to spend its entire life doing bench rest shooting 16" carbine length seems to be the best combination of accuracy and lightness/mobility/commonality
Ballistics on 18" and 20" barrels arent really that much more impressive than 16" from what I've read.
Way to be a retard.
Think about it like this op. Are you building a full sized rifle? A mid sized rifle? Or a carbine? For reference a rifle is 20"+, mid is 16-20, and carbine is 14-16. You can mess with different bcg and buffer systems to extend the range of each.
>You can mess with different bcg and buffer systems to extend the range of each
I like mid-length for the reason 18" barrels should be rifle length (or have adjustable gas blocks). It's ever so slightly easier on your rifle when you suppress it. I plan on going mid-length because I plan on suppressing my rifle. Either that or I will go SBR and build a mk18 clone.
I have a midlength and I agree. I actually like the 7 inch carbine length handguards tbqhhh
It doesnt make it lighter and more mobile than a midlength, but carbine parts are more common than midlength.
I was saying 16" carbine is lighter and more mobile than an 18" or 20"
Carbine; 11.5 , 12.5 , 14.5
Do not buy a 14.5 Midlength. No reason you are merely adding potential issues. Midlength was developed for 16" and you also can no longer utilize bayonet with a 14.5" Midlength.
Is there any real evidence that midlength has any measurable reduction in wear over a carbine length gas system on a 16" barrel?
Seems like the Internet just repeated ancient bullshit posted on arfcom so much it became fact.
I feel your pain I have a 16" BCM midlength upper sitting in the safe because I don't like the way it looks. Once i cut down the sight and throw a freefloat on it, it should be good.
The closer the gas block is to the chamber, the harsher the extraction and more violent impulse and higher the pressure. The difference is huge.
By the same token, the more barrel AFTER the gas block, the longer the dwell time and there is a curve where too much will just be increased pressure and wear and too little will cause short stroking.
Midlength was developed to lessen the increased wear on extractor/bolt and allow the same amount of barrel in front of the rifle as a 14.5" Carbine.
You also cannot mount a bayonet on 16" Carbine or 14.5" Midlength. Keep your 16" to middies and your 14.5" to carbines and 20" to rifles.
Use the best length system to optimize performance and reliability of parts.
Yes it is measurable and yes as you enter the say 10,000rd mark you will see a signifant difference in wear n tear.
but you will not notice it's significance if you are just a hobby shooter.
not always and
even if it doesnt have a bayo lug, guess what, a bayonet can still be attached.
is it dumb? sure, but we were simply talking about what is doable.
basically, you can put a bayonet on anything, why youre claiming contrary, i guess you didnt know. well now you do.
Your barrel if it's CMV and Chromed it should definitely not be at the end of it's service life at 10,000rds. Get a better barrel dude.
IF YOU WANT *OPTIMAL* PERFORMANCE GET 16" MIDLENGTH
IF YOU DONT GIVE A FUCK GET 16" CARBINE
It doesnt matter to most but if you have an option there is no rational choice to a 16" Carbine.
Woah dat projection.
I am not mil but I am LE. Hobby shooter ie; Someone who goes to the range every other weekend.
If you shoot in any large volume then you should probably get the best gas system for your barrel length.
Ha, your garden variety leo putting more rounds downrange than a hobbiest.
OP, despite what you're seeing here, a middy gas system works fine on a 14.5" barrel. Along with the 1.5" reduction in barrel length, the recoil impulse is softer compared to a 16" middy. It's also softer than a carbine setup. If you're keeping the A2 FSB, you have better sight radius and more railestate compared to a carbine. 14.5" middy is, as a bonus, also sexy as hell. Whether you think that'll be worth the extra $200 is up to you, but I have absolutely no regrets getting my 16" middy cut down to a 14.5" middy.
I have no doubt that your "garden variety" LEO does not put as many rounds down range as a typical /k/ hobby-shooter.
If you dont shoot much, get whatever you want.
If you do shoot alot (even as a hobbyist or patrol officer or non-grunt .mil) then maybe you should consider getting the best bang for your buck which would be middy if you are going 16" or carbine if you go 14.5".
Its softer (btw its a fucking .223/5.56) at the expense for reliability in adverse conditions, and you cannot mount a bayonet. This makes literally no redeeming factor for a 14.5 middy except aesthetics.
Guns are tools btw, and who gives a fuck how slick a 14.5" middy looks. I am legitimately interested in what the benefits of a 14.5" middy are over a 14.5" carbine or 16" middy. Because so far I have only seen it being a solution looking for a problem.
I feel as though most people prefer 14.5 to 16 but to be honest I kinda wish I stuck with 16. My next upper is probably going to be a 16 again; I love my 14.5 but I like having he option of changing muzzle devices.
>but if silencerco and BE ever make an ASR 249, I'm getting a 13.7
What the fuck is going on in this thread?
>14.5 or 16 - Middy
>Under 14.5 - Carbine
>Over 16 - Rifle
>at the expense for reliability in adverse conditions
Good thing the experienced folks at ADCO are able to determine whether any measure needs to be taken to improve reliability (spoiler; it involves widening the gas port ever so slightly). I'm interested to see how you came to the conclusion that a 14.5" middy isn't going to function.
>and you cannot mount a bayonet
Oh no, I can't use an archaic fighting method that sees almost no use in the past half century. If you're that determined to mount a stabbystabby on your shootyshooty, there are easy fixes for a 14.5" middy.
>This makes literally no redeeming factor for a 14.5 middy except aesthetics.
And reduced barrel length, and reduced weight, and softer recoil impulse. You know, those little things.
> I love my 14.5 but I like having he option of changing muzzle devices.
Now this is a valid complaint. Unless you SBR it (and it honestly doesn't get much more retarded than going through the entire SBR process for 1.5" in reduction), you're stuck with whatever MD you have P&W'd. I stuck with the A2 FH because it never looks bad and it does what it's meant to well enough. For more discerning individuals, it could be another story.
The same can be accomplished with a 10-13" free float handguard of some kind and flip up or fixed irons up front, but with even more sight radius and ability to grip the weapon out further--nice for Sasquatch tier guys. This is the reason I hate carbine handguards, I feel too scrunched up.
Does middy work on 14.5 inch? Sure. And if that's what blows your hair back, good on ya. Only reason I'd go that way was if I just had to keep the A2 sight
>Only reason I'd go that way was if I just had to keep the A2 sight
> If you're keeping the A2 FSB
To be fair the recoil impulse on 5.56 is small.
I really don't see any difference between mid or carbine on a 16" other than shooter preferences, and thats fine. I really don't see any documented proof about wear/reliability that people claim.
I like my FSB
>To be fair the recoil impulse on 5.56 is small.
That it is, I was still able to discern a different in felt recoil in my middy after it had its barrel reduced. Softer impulse is always a plus, even if what you felt beforehand wasn't really anything to write home about either.
Holy fuck, you people are hopeless
I'd expound upon the advantages of midlength gas system (really no cons), but the vehement retardation I see here really turns me off
I'll say that if there's a $200 difference between the same gun with just different length gas systems, you need to look elsewhere
>if there's a $200 difference between the same gun with just different length gas systems, you need to look elsewhere
This is also true.
I really can't bring myself to get rid of mine, the look is too defining of the AR rifle.
I am thinking of going 14.5" middy but I have questions
a) Will I need a retarded 1.5x length A2 if I want an A2 like you have
b) How well will it do suppressed, special considerations
c) If it's softer shooting wouldnt that mean there is less gas pressure and wouldnt that mean less reliability because that freaks me out.
>I really can't bring myself to get rid of mine, the look is too defining of the AR rifle.
I agree, if I change anything on this AR, I'll pick up a Centurion C4 Mid cut-out rail and sell the LaRue.
>a) Will I need a retarded 1.5x length A2 if I want an A2 like you have
If you go specifically 14.5", yes. Honestly, I went with 14.7" so I could keep the standard A2 FH, because fuck that elongated shit.
>b) How well will it do suppressed, special considerations
I honestly have no idea. You might shoot off the folks at ADCO an email asking what their experience with that is.
>c) If it's softer shooting wouldnt that mean there is less gas pressure
Yes, but this can be compensated for, if it needs compensation at all to begin with. Don't shoot underloaded crap like Tulammo and stick with a standard carbine buffer. I've shot mostly Wolf Gold through mine, but the few hundred rounds of Brown Bear it's seen gave it no issues whatsoever.
Git a carbine gas system for 14.5in barrels. It looks better.
Since picking my MCX I've also realized how little the 1.5 inches really matter from a handling perspective. Obviously if I were to do tacticalfagtical urban or vehicle ops, a 14.5 is going to suck just the same as 16.
I still think 14.5 mids are the most asethic, which is very important to some people, but I've become somehwhat disinterested in 14.5's now that I have a 10.3
>who cares about bayonets
>WHO CARES ABOUT BAYONETS!!!!!!
Say it again! I FOOKIN' STAB YOU!!
I think he meant it as "get this thing from someone that knows their shit, and that is someone who cares about bayonets".
That's how I read it, anyway.
Also, in the pic you posted, they all seem to be m7 models. What have you heard about the OKC 3S? I'm looking into one for my AR, a 16" mid length.
Because they look absolutely retarded.
