16" Mid Length - Carbine or Rifle buffer tube?

[BLQQD]

Soooo I was led to believe that a rifle buffer tube would provide smoother, better action than a carbine tube.

Is that BS or is there some truth to it?

Carbine, there is no reason to go rifle unless you intend to make a long range rifle and that would be a 20"+ or greater barrel.

The Rifle buffer will not make a smoother shooting gun, your gas tube length will make way more difference and the buffer weight would be 2nd.

I run a 16" Mid length and a 20" Rifle length gas system both with Carbine buffers.

Just a heads up Rifle buffer does not collapse, only Carbine, if that matters to you.

It's BS

I'm pretty damn happy with a Spike's ST-T2 (4oz) & Sprinco "blue" in my carbine length extension tube. This was going from a carbine buffer & standard spring.

What stock do you intend to use? That choice usually drives which tube you need.

I run a DelTon 16" 1/9 mid-length upper on both a clone A2 rifle and M4 carbine lower with no issues shooting mild 55gr range, XM193, and XM855 ammo.

This. Pick which stock you like best, and then figure out which receiver extension (buffer tube) to use from there.

Carbine tube.

And if you want super smooth then throw a little extra cash for this... https://geissele.com/super-42-braide...fer-combo.html

That's correct.
The rifle gas system runs a heavier buffer and a spring with lower spring rate.
The carbine system has to use a higher spring rate to offset the lighter buffer weight.
The trade-off of going to a lighter buffer and more spring tension is harsher function.
The smoothest cycling AR's use rifle length buffer/spring and rifle gas systems.

I am using a rifle stock on my 16" 7.62x39 and it runs very well A1 stocks are a great choice or cav arms a1 style

Cool, thanks

Ahh, I thought so. People were making fun so I was starting to doubt lol.

AR15barrels is correct. I use that same setup. Midlength barrel (although mine is 18") with rifle buffer and it has a lessor recoil pulse.

I went with the 9mm buffer which is a hair bit heavier than a H3. but it's just solid with no play but the h3 has weights which you can hear movement inside the buffer.
