Slow-motion AR-15 cut-away buffer tube cycle comparison: standard; light spring; empty buffer
AR-15 with 16" barrel, carbine-length gas, firing XM193 (55gr 5.56mm), recorded at 2111fps, to show the effects of switching components in the buffer tube. Good background can be read at https://www.guntweaks.com/ar-15-relia...
Top recording shows a standard spring with a standard carbine buffer (which is detailed at • AR-15 Buffer Weights .
Middle recording substitutes a buffer spring that has been trimmed in length by 15% to 10" uncompressed. This increases the cyclic rate.
Bottom recording keeps the standard spring but removes the weights from the buffer. This also runs faster, but there is significant bolt bounce at the end of the cycle.
