Are the individual weights the same outside dimensions whether for a carbine or a fixed stock like an A2? The reason I ask is because I find nothing specific for A2, rifle-length, etc for individual buffer weights. And because of this statement:

"Rifle vs Carbine

Rifle length buffer weights are used when a standard A2 buffer tube is installed for a fixed stock. The extra length helps to fill the void in the longer A2 rifle buffer tube. Carbine buffer weights are used with most collapsible stocks that utilize a carbine buffer tube. Generally, fixed stocks use an A2 smooth buffer tube and adjustable stocks use a carbine buffer tube. Most of the stocks on the market use a Mil-Spec carbine buffer tube and are adjustable for length of pull."

Was considering the KAK Industry AR15 Configurable Buffer Kit until I read the above.

Thanks
