Seriously? Raw hm1000x

[efrobert]

I just got a new Raw hm1000x Blue laminate .25. Just got is all set with an Arken 5-25x56 and a Impulse Air 1325 moderator. I shot 5 Magazines and all of a sudden the pellet probe is just flopping around loose. WTF? Is the fix for this tightening the little grub screws? I can’t find an allen wrench that small in my tools. I’ll have to pick one up.
My first PCP was the $299 Gauntlet when it first came out and I’ve never had an issue with it, but a $2000 gun and I’m searching the internet for a fix after 60 pellets. Frustrating.

Just the opposite of my experience with a Gauntlet and a Crown.
That is a bummer. I hope its a simple fix for you.

I’m guessing that gun is set up to switch calibers easily so the probe will be made to be easily removed and switched as well. Therefore I’m sure the problem is just a loose screw(s).

I can understand the irritation. However, consider it necessary to obtain torx and allen tools, you will inevadibly be needing them.

 

[corny]

So the tiny Allen screw isn’t tightened down in anything.
It simple keeps the complete probe assembly inside the carrier.
If it’s loose, just use a little bit of blue lock tight.

As a whole….those probe assemblies are pretty bullet proof

The pellet probe in the RAW is supposed to be a little loose (flopping around). Much different than other guns. That's so it can accurately follow a pellet into breech and seat it squarely with the barrel.

I believe the hex screw is 1.5mm from recollection. That grub screw controls the sealing pressure of rubber button against the barrel. I'm sure there is an easy fix to be had.

Like Ross said above, both the outer bullet shaped probe and inner seating probe have a little movement to seat projectiles properly...it is a little disconcerting in the beginning...it is a mechanical wonder though.

IIRC - the hex screw is smaller than 1.5x, something like 1.3x .... not a standard size

I have to change out the probes when changing calibers ... for older eyes this is a challenge unless there's plenty of light.

I’m pretty sure it’s a machine steel to steel sealing surface with no rubber. At least the 3 HM1000X’s that I owned were that way, unless something has changed in the latest iterations?

It sure would be nice if airgun manufacturers offered thorough cross secrion views or good exploded views.

 

[shambozzie]

Note from Martin: No oring on probe/barrel. The tolerance is that good.

 

[SpiralGroove]

Yeah I've made .177, .20 and .22 barrels for my RAW HM1000x's out of LW blanks - pretty easy to cut a barrel on the lathe and to get a perfect seal with just the metal probe. A very nice design by Martin.

 

[corny]

In some of the older versions of the probe, there was also a grub screw to lock the probe length adjustment thread in place.
But these days all that’s used is locktight.

There is no oring or rubber seals in the raw probe assembly. Simple tight machining to seal the air out of the inner probe. And the steel on steel tapered seal at the breach.

Imo, the best probe assembly I’ve used or seen in an air gun. Always the same, no scraping or scratching…it just feels good. That snap…when it goes home..just awesome.

Just a follow up. I contacted RAW and sent them pics and a video.
They got back to me right away. Great customer service. Problem is the the Bolt stem base is bent causing it to stick in the bolt. Basically the little pin that pushed the pellet into the gun is slightly bent. Raw is sending a new part. Easy fix. Thanks to all that commented.

 

[Ranchibi]

One of the best PCP customer service support one can get, especially str8 from the owner/builder! Glad you will be up and shooting your new RAW soon .

I think, don't quote me....it's a 1.27x....

Don’t throw out the old pin…can easily be straightened.
That being said, if that pin bends it will jam up the probe inner and outer movement.
It shouldn’t make the whole probe assembly fall out of the carrier…
