Why use a .308 carbine spring in a large-bore AR pistol buffer system?

A .308 carbine spring provides increased spring resistance compared with many standard AR-15 carbine springs. When properly matched with the buffer and firearm configuration, it can help manage the cycling characteristics of compatible large-bore and high-energy AR platforms. Buffer and spring requirements can vary by caliber, barrel length, gas system, and operating configuration, so components should always be matched to the specific firearm.
