Extractor broke within 2k rounds

Fun while it lasted, will throw in a bcm bolt as the bcg isnt too worn
Dead at around 2.5k
by Ethan -
Got this BCG to see how far it would run through an 11.5. It was run on range days and at matches to around 2.5k ish rounds. The last week it was used for 2-3 hours with anywhere from 2-600 rounds being fired(daily). After 140 rounds or so on the last day the bolt gave out. Impressed that it was able to hold up as it was purchased for 90 bucks on sale. If you're looking for reliability this likely isn't the best choice, but if you don't shoot often it will work. I would stay away with shorter barrels and gas systems for the same reason. It does what you'd expect at this price.
Works well

Although have not had the opportunity to use this BCG yet. When compared to other BCG costing 2x as much, this does appear to be their equal so far.
Good first impressions
by TAz -
Good first impressions, good staking and machining. No mpi or c158 marking on bolt unfortunately. No issue when cycling snap caps. Will update the review if there are any issues.
