Marauder 25 Gen 2 reseal

[fr8rbum747]

I have been shooting my Bobcat MK2 so much lately that some of my other rifles have been sitting neglected, in the dark. I never thought that I would not be shooting all of them on a regular basis and that has caught up with my 25 SynRod. It was the fifth of my rifles to come out of the locker. I prepped it for a shooting session when an O ring let go and lost my air charge. A little disappointed but then realized I had not shot this rifle in several months although I had checked it over just last month as I do with all my weapons. So Joyfully I now have it torn down and will be upgrading some shiny components internally. A little more internal corrosion than I expected but then again not as bad as I have seen in other rifles I have resealed from other shooters at the range. Better check that Air Dryer on the compressor. So I have expanded my card system that I utilize on the PB's to include a sign out date and usage log for my Air Guns. I guess another remedy would be to sell off some of those that have become Safe Queens, NOT...That is what my wife suggested. It just means I need to vary my shooting more and increase my hunting trips.
Resealing and maintaining is not difficult just a fact of life. These Benjamin Air Guns are great when you decide to try some of the mods in search of that sweet spot and improve your accuracy.

I replaced the air tube on my Gen 1-the Marauders are easy to work on.What mods are you considering?

I have modified other Marauders I have but was just going to start with a reseal and go with the WAR Hammer mod. Installing the WAR Hammer requires cleaning up the main tube and smoothing all the sharp edges of the internal main tube. I also have two Hill Air Valves sitting on the bench so one of those will be going into the reseal project with a stronger spring. I am not looking to over power the rifle, I have a big bore with plenty of foot pounds already. I also have a regulator that I may throw into the tube to flatten the shooting curve for better consistency remove the gauge block and install an extension on the main tube.
The rifle was always a good shooter and since I have the parts on hand why not put some to use.

After second reseal of the main tube the Manometer popped with a hissing of the 1000 psi I had put into the main tube for seal testing. This may have been my problem from the beginning but have ordered a couple of new gauges.

New manometer from McMasters installed no leaks. Looking forward to some chronograph work with the new Hill Valve and WAR Hammer. Will publish specs after tuning. Decided not to regulate the 25 Syn Rod just go with most consistent pressure and fps for hunting on the curve.
