Included
-Bottom and Endcap in 6061 black anodized aluminium
-pre-installed fartflap
-Bottom Cap removal tool
Installation
-after removing the original Bottom Cap, add a little bit of grease to the threads. Vaseline will work just fine.
Pay attention: The original bottom cap can be stuck quit firmly, so no guarantee it comes loose. Sometimes it helps to use a vice (Dutch: Bankschroef). The threading is CCW (CounterClockWise), just like your outer barrel. If you really cant get it off, message me, we can work something out.
