I have changed out several screws on my HOO6 Big Boy Brass
Posted: Thu Jun 18, 2026 10:10 pm
I purchased my .44 Magnum Henry Big Boy brass rifle used last year.
The previous owner didn't have screwdrivers that properly fit the screwdriver slots, and many had damage from cleaning the rifle.
I bought several Ranger Point Precision quick takedown screws.
One for the lever, the second for the buttstock.
I still need about three more replacement screws from Henry, then all that have screwdriver slot damage will have been replaced.
I just haven't taken the time to call Henry Customer Service yet.
The Ranger Point Precision items? Very nice quality machining. They fit and function perfectly.
I don't know if I will ever really need the quick takedown features when out hunting, but it's nice having that feature available if ever needed.
The lever takedown screw is just finger tight with an O-ring so it doesn't accidentally loosen, and the buttstock quick takedown screw is machined with a radius in the screwdriver slot for using a coin or flat washer, and a pair of pilers.
I also bought a spare inner magazine tube. I got all my parts from Midwest Gun Works.
