Can running too light of a buffer damage anything?
Is a Spikes T2 buffer with carbine spring and spacer an OK place to start? (what I have on hand)
Are solid (no sliding weights) buffers a viable option in a 9mm? I have seen solid buffers that are pretty heavy (~5oz) for cheap.
Application is an AR pistol with 7" barrel, CMMG bolt and dedicated lower with KAK car length extension.
