Buffer guestion.

[FastPhil]

Is a standard AR buffer and spring for a 556 going to cycle a 9mm AR or is this something I'll just have to try an see what happens ? Is the spring and buffer lighter for a 9 mm . If so is this something DSI would normally stock.
Thanks. Feels good to post gun crap again after you know

Meh DSI, give Jerry's a call. I'd be surprised if it cycles, no idea though.

You need a 9mm specific buffer.
For illustration only, I'm sure you can find a less expensive one somewhere else.

This is the setup I use

Specific 9MM Buffer and spring. Is this going to b a dedicated AR in 9mm? While others may disagree ,I'd only utilize it as such to avoid the buffer and spring swapping etc. when going to a 5.56 rifle.

[SlowTime]

You need to use a 9mm buffer or a heavier 7.5-9 ounce carbine buffer with a spacer.

[FastPhil]

It's a dedicated 9mm. 16" barrel and uses Glock mags. Thanks for the info. Would have hated taking it to the range just to find out it won't cycle

[Mega2899]

Phil can you pm me your build list if not too much? I'm wanting to build a 9mm ar also and want to see what I need.

[Dank27]

Heavier buffer. And dont buy shit from those fucks at Dick Shit Industries

[angelonm]

There is a heavy buffer for 9mm use. Also look up sprinco springs. They make various buffer springs for all setups.

[LazyLab]

Get a 9mm specific buffer and a 9mm/.308 spring.
joebobs has both.

OK so I've been doing some homework today and now understand the reason why a heavier buffer and spring are needed, The main difference is the blowback system of the 9mm. For smoothest and quietest function with the lowest recoil it looks like the Blitzkrieg hydraulic buffer is the way to go. The buffer spring in generally the same as a spring for an ar10. The freaking buffer is going to cost more than the PSA Glock style lower

[LazyLab]

Why not go the cheap way with a buffer and spring? Who gives a fuck about the noise, the louder the better!

[Li02liberty]

Phill you can also use a heavy carbine buffer and drop 7 quarters in before you put the spring in as a spacer. That's how I run mine and no problems with it.

But you might hurt a liberal's ears. Stop being so rude! You made that Kuntzman guy cry!
