Metal replacement caps for Big Boy Sound Moderator

New : Aluminium Bottom and End Cap for the one and only Bushmaster Big Boy Silencer If you have a Gen 2 Big Boy (with removable bottom cap), you this cap set is backwards compatible. Screw the old caps off and install these new aluminium ones set weight : 155 gram I just received the first batch, but I am adding new ones as fast as I can, so stock is limited for now. 2nd (very large) batch expected end of September 2026 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.
