The piece that...
The piece that connects to the bottom part of the magazine is missing an internal front guide. The result is that the platform the bullet rides on gets stuck after the 25th to 26th round, so the spring does not push the rounds up the magazine. This will cause a failure to feed and render the extension a fatal excessory.\\r\ Buds is good. order fulfilled quickly even with everything going on.
