This is not a "hard use" BCG
This is considered a consumable part, AR's with dialed in gas and buffer systems will prolong the life of this item
Recommended gas systems- Mid length, Rifle Length, or similar
"How long does it last" The original unit is still being tested everyday in a 12.5" mid length gas upper with high back pressure suppressor, mostly on full auto, no abnormal wear so far.
300 blackout, if you were having cycling or magazine lock back issues, this is your fix. I always carry an extra to help others at the range. Happy shooting!
