I just got my BSA probe for mine today, I'll need to put a spacer on it but right now if I just eyeball it I can use it. It goes in too far the way it is but it's a nice stainless probe too, it was on the pricey side ($26 to my door) though. I did put 1K in the gun already but I'll exhaust it before I reassemble the gun.
Wayne, I think you'll like the rifle after you shoot it, I just wish it was about a pound and a half lighter like my Marauder is now with the JSAR air tube. Was shooting mine quite a bit this morning and noticed a few things I'll share with everyone, I was shooting JSB 18.13's until my 15.89's get here from PA, was using the single shot tray and shooting at 30 yards, accuracy was very good, had lubed the pellets with the Napiers that finally showed up and was very happy with the groups. When I switched and started using my Marauder mags instead of the ss tray my group moved to the right 1/4 to 3/8". Went back to the ss tray and group was dead on again. Then switched and tried the mag for the Liberty, the group moved 1/8 to 1/4" right again. Went back to the ss tray and group was dead on again. To be clear here, the pellets still grouped well when using the different mags, they just moved to the right for some reason. Gonna shoot some more and see if this continues to hold true, if so I'll have to adjust if I want to keep using the mags.
It looks great RDB! What did you use on it?
I've posted here about the plenum I have been developing. This post is getting long, I'm starting a new subject specific to the plenum and future Liberty parts.
Does anyone know if the "05-2018" to the right of the "(300 Bar) is the manufacturing date
I'm glad someone got a similar result to mine, also glad to hear that the gauntlet mags caused no shift. If the Liberty mags cause a 1/4" shift at 30 yards imagine how much more pronounced it would be further away at 50 60 or 70 yards. That and the Marauder mags I was using was even worse.
