Tuning Maverick pellet probe alignment with Huma pin probe

For a sake of convenience also to eliminate any possible human errors, me personally I would retract the probe as a first step, and go from there.

The problem with the pin probes is that there is a larger variation of slugs lengths and how can you make the probe generic to work for all. If you decide for a certain Brand and length you can eventually cut the pin to that specific slug. I don't see any other way around. Or, yes, there is a way...order a adjustable pin - custom probe from your lathe guy.

I had this exact same issue with my wildcat MK3, Swapping out the factory pin or pellet probe. As you’re aware they use the same equipment. The humor probes and the factory probes are the same length total, however the hole for the screw pin on the probe is in a different spot, slightly forward on the humor probe. This has caused humor to be about 1 mm too long. I thought for sure I was doing something wrong, adjusted everything from the body of the gun to pellet pro length within the block. But no matter where I put the pin or pellet probe it always ended in the same position when cocked. I called huma and they are aware of it but don’t seem to be in any hurry to change anything. Once I noticed that the hole on the pro was in a different spot, I simply used some sandpaper and some time and slowly took off the 1 mm so the magazine would enter the gun without having to pull back the lever all the way which is not effective when hunting or needing to do a fast mag change. I had success with this and the gun is working fine now. As for the pin probe I just took off just enough for the magazine to clear when cocked normally. For the pellet probe once I had the 1 mm taken off I redid the centering of the pellet probe and the transfer port. Everything is lined up nice now and the gun is firing just fine.

..... I'll keep that in mind when considering my next purchase....

Don't worry sooner or later you will go back to them again to buy the next trick....never say never...Huma is a good brand regardless you feel like you have to do some elbow greasing now for the money.

btw, that you pin (B8 probe) is for the longer slugs. Remove the long top plate (B14) and extend the probe holding block long rod (B19) for that 1mm how much you say - missing, and voila you just cleared the mag.

Edit: sorry I just realized you talking about Maverick, these my balloon numbers are from the Impact BOM, but you got the picture.
