  • @SuperLouis420 I guess it depends on carrier ang gas system length

  • Then number of samples taken based on the variables that can cause bolt bounce - even using different carriers ... doesn't seem very scientific. There is really little difference. Not enough to be statistically significant based on the number of tests you did. How a round seats against the magazine lips could cause more variability in the bounce than the buffer weight. Prove me wrong. Do a proper experiment with standard deviations within a sample set.

  • Is this a buffer bounce test or a lock-up test?

  • Which one is best? I just ordered a heavy bcm carbine buffer for my 16" carbine.

  • @wittzo I fully agree Sir and that is what I meant by "stacking", I enjoy and appreciate the discussion regarding these weapons......Thanks!

  • @buttercupG19 If you notice, I said,"If it was worn or out of time." If a device is worn out or built out of spec on the cheap, all sorts of things happen.

  • @wittzo You have forgotten the fact that the "Ejector" is spring loaded and that would "Normally" precluded the cartridge being fully seated within the shrouded bolt and it must be fully seated against the bolt face in order for the firing pin to contact the primer. BUT.....stars do all get into alignment on rare occasions and "stacking" of problems do occur. Thanks for the video.

  • @YAYAJACE one word: lube

  • @FLATblacktical I run the same setup you do, except mine is a mid-length. Also no malfunctions. No malfunctions, no problem. If it ain't broke don't fix it, eh? :) Bolt bounce is something to worry about when you're shooting strings of full auto. Apparently we can't shoot fast enough on semi for it to be an issue.

  • colts are over priced i guess.sounds like your gas ports are too small or some crap
