Rifle or Carbine buffer tube for DMR build?

Finally got my "snaipa" rifle upper built. Question on the lower build, I'm definitely getting a fixed or lockable stock, but what buffer system, carbine or rifle, would be best?

Setup is: 20" 1:7 rifle length gas tube.

Experienced advice needed.

Thanks!

What stock are you going with?
The buffer tube length will determine which buffer style you need to use. Carbine or rifle?

I'm wondering more about which would be a better buffer system to use for my setup, Carbine or Rifle, or is there a major difference?

If I go with the carbine buffer system I'll be going with a Magpul MOE Fixed stock or Vltor Emod. If I go rifle buffer system I'll be going with the Magpul Rifle Stock or the Vltor ARM.

I should have been more specific in my question. Gas port size and if you are using adjustable gas or not is what I was after.

The main differences are length, and buffer weight. Rifle buffers weigh 2.2 ounces more, and is longer. They are also intended for fixed stocks, or ones that adjust on the stock itself, and usually have a longer LOP. Carbine buffer tubes are intended for adjustable stocks. Ones like the ACS have a locking tab. So that is all ergonomics.

Depending on your purpose and technique, there are operation differences. Many competitors with a rifle length tube spend the extra coin for a light weight rifle buffer. Less moving mass means less recoil in the 3rd and 4th impulse, which is what tends to move the sights around. With a carbine tube, you are already at "low mass".

Realize that the buffers can be adjusted by swapping out spacers and weights as well.

So pick the ergonomics you want, and then deal with the adjustment of the system to include gas, buffers and springs. Either can be set-up just fine.

Pick the stock.
Shoot the weapon.
Tailor the buffer weight to "tune" the ejection pattern with the ammo you are using.

There is no solid "canned answer" without knowing all the variables.

Thank you faawrenchbndr and MarkCO. Just the info I wanted to hear.

MarkCO, the gas system is a shaved FSB. So I guess I'll be tuning with buffer weights. I might just go with the carbine buffer system due to versatility.

Thank you again.

My 20" runs great with a UBR and H buffer, pick what you like and see how it does.

Another option is the VLTOR A5 system which uses a rifle weight buffer and spring but uses carbine stocks.

You are most welcome. I've been running carbine systems for a while. Gave up on adjustable gas a long time ago and rifle buffers a while ago.

I have 3 springs (-10, standard and +25) and 5 buffers (2 ounce to 6 ounce) on the bench just for set-up. Check ejection patterns and look at the case head for ejector and extractor wipes. When I have it how I want it, those testers go back on the bench and the new rig gets that combo.

That's what I'd go with, I'm not a big fan of rifle LOP, VLTOR A5 keeps LOP reasonable, lotta guys even run the A5 on SBRs and like it.
