AR recoil beliefs

[ARlife4me]

for most beliefs (lets say same gas port size regardless of platform and cartridge) less recoil mass equates into less recoil...........makes sense right...........some don't believe this to be true and stack an h4 (or heavier) along with a heavy bcg to reduce recoil..................does it really..................in some circumstances it does............for an unknown/proven cartridge out of safety reasons i used a 9.5oz buffer in my 6.5prc (since i had no experience with short mags in an AR) and the gun produced extremely little recoil.............in most part i believe and have used a low of weight recoil components (lm-bcg & buffer) in various platform and cartridges in both that have cycled perfectly and produced little recoil in a low weight rifle. none were a select fire or full-autos which would probably need heavy recoil components to cycle under these types? what would a + or - weighted spring really do/provide? bolt bounce?

what are your beliefs and experiences with any or all?

In my experience, if the gas port is sized to fully cycle the BCG to the rear, and no more, when you install a heavy buffer and/or spring, it short strokes. I don't really see the point of intentionally over-gassing the gun, then adding a heavy buffer and spring. But I don't know....that's what all the cool kids like to do these days.

If the gas port is already over-size and over-gassing, then install an adjustable gas block and turn it down.

that might be some ways to deal with issues and is usually promoted to do so, but there's more ways than that/those in my experiences. muzzle blast comes from via many ways, so a heavier buffer might not be the answer. barrel length, powder used, which cartridge is causing this and so forth. accuracy has nothing to do with buffer weight. not sure why someone would even post that? the beer part is the only plausable solution to all the above
