A tale of 3 Ghosts šŸ‘»

2 of my amigos and I purchased some BRK Ghosts šŸ‘». They are all .25 HPs. Here is the tale of what transpired as tuning beganā€¦ā€¦ā€¦ā€¦..

They showed up from AoA packed beautifully well. All clean, pressure tested and ready for work. Triggers all had some second stage drag before let-off. All triggers broke at 1lb 6 ounces. I let each of these 3 jokers know that this wasnā€™t going to be an acceptable trigger behavior! This is when they introduced themselves. Black Max seemed to be the ring leader. Foghorn quickly let me know his trigger was just fine and he wasnā€™t happy to hear any lip from me about it! Spook jumped out at me, screamed boooo, following the scare with a big smile šŸ˜€. I wasted no time in taking each down and intricately submitted one by one. Black Max got the guillotine, Foghorn the Kimura and Spook the rear-naked choke! Once Alpha Dog šŸ¶ status was established, I got down to business!!

Black Max got a 4.5 ounce second stage break. Foghorn an 8 ounce and Spook a 4 ounce. None have any goofy sear drag and all triggers let-off crisply! An aftermarket first stage spring was utilized and I trimmed the rod-linkage springs so as to achieve the requested trigger pull weights.

I next completed my port/polish on the barrelā€™s transfer ports and blow-through probes. I then addressed the shroud frame clearance and gave all .016ā€ spacing from the frame. I
Inspected all fastener while I was at it and all looked great. Barrels all got cleaned with Gunzilla.

The BRK Ghost is a very well made PCP. When getting under the hood, you know youā€™re in the presence of a well engineered piece of equipment.

Set all 3 Huma regs at 150 bar and tested over the chrony. All performed great. These crew of Ghosts were now ready to rock!!

Black Max got the call to the bench first. Itā€™s very first 5 shots at 100 yards looked to be about an inch ctc. Foghorn followed with a good showing and similar accuracy. Spook shot steel at 100 first then paper and produced about the same 1ā€ ctc 5-shot groups.

This was all done with the 33.95gr JSBs. All produce the same power at 150 bar ~ 960 fps on Max (19) and 925-930 on 10. The firing cycle is nice, clean and easy on 10. I found 925 to 940 to produce great accuracy. Filling to 250 bar produced 55 regulated shots at 925 fps with the 33.95gr JSBs. SD was 3.6 fps and ES was 13 fps.

These 3 Ghosts have vowed to strike fear to any and all that challenge them. Iā€™m certain we will see much more from Black Max, Foghorn and Spook šŸ«¶

Letā€™s get it!!!

Nice write up. Looking forward to trying the Mk1 Heavy and fine tuning speed. (Mk2 Heavy were used in the groups above). Foghorn will be on his way to me soon. Great job with all three guns Derrick!

Foghorn has one last task to make it into the starting lineup for 2023 competition in Extreme Field Target and EFT GP events. Heā€™ll go head to head with Reaper, my .30 FX Bobcat Mk2.
