Great option - ODIN Works AR-10 Adjustable Buffer

This buffer fixed a cycling issue I was having in my AR 10 pattern rifle. Most large frame buffers lean toward the heavy side but you have few options when you need a lighter buffer, this product can help you there. Moreover, you have the option to install three tungsten weights if you wish to go toward the heavier side (purchase from Odin Works). It also gives you the capability to tune your gas system when adjustable gas systems are not possible or desired. I used this in a rifle length buffer tube with no issues. My advice is to add this to your build list.
