Home Forums Hunting & Shooting AR and Tactical Rifles Still learning-another question

I understand that the shorter barrels increase gas pressure and strain on the operating system more so than rifle length barrels.

This can be tuned with heaver buffers in a carbine like the heavy buffer and H2,H3. Also gas tube sizing.

My question is what buffering rate are you getting if you are running a 16 inch barrel on a fixed full length rifle stock with rifle buffer and spring? Is the standard rifle buffer heavier than a standard carbine buffer, its longer.

Have not seen the weight listed for a rifle buffer just the carbine buffers.

Here's some info on buffer construction and available weights:

Found out the buffering is the same with rifle buffer and spring and standard carbine buffer and spring. The spring rates are different.

So are there heavier rifle length buffers avaliable?

Thanks for the info.

The Canadians just run a standard rifle buffer in their fixed stock rifles. I can't recall the designation the Canadian military uses for their rifles, but they are in service with them in that configuration.
