PCP Changing barrel on the HW100 from 600mm to 410mm

[ernroe]

Has anyone had experience changing out the barrels on a HW100? I like my HW100T but don't like the 23" long barrel, so I bought a 16" barrel from AoA to replace. I am fairly sureone here has experience changing barrels. I would appreciate any info. BTW, I went on You Tube and found everything but specifically changing the barrel. When it is all said and done the overall length will be equivalent to my AA S510.

Did the barrel come with a bonded moderator?

No, it is threaded for moderator. AoA said heat up moderator where it connects to brl and melt the locktite. Screw it off and attach to new barrel. That sounds simple, I have a heat gun. What I need to know is how to take the current brl off.

Is the new barrel threaded? Does the new barrel have any shallow flat bottom drilledd holes for a set screw to hold the barrel in its correct position? Inspect the breach end of new barrel it should give some clue. If nothing else call aoa

It is set up to be helt in place by "Grub Screws" and the muzzle is threaded. AoA sold me the barrel as a replacement for the 600mm brl. It is a Weihrauch HW100 brl just shorter.

Ok so remove the grub screws slide barrel out slide in new barrel in and replace grub screws-don’t over tighten you will dent inside.

If it’s held in placed by grub screws, then it probably has O-rings. Be careful with with them if you don’t have replacements. Make sure to use a small amount of silicone grease.

Did the new barrel come with any?

Thx for the info. It helps to have some idea of what you are doing before you do it. I will you know how it goes.

Ohay, thx to y'all I know how to change the barrel. One more question and I promise to leave you alone....for a while.
AoA says heat up the moderator to melt loctite before trying to unscrew moderator. I have a heat gun, but before going forward I would like to hear from someone that has removed a a Moderator from an HW100. This gun is the 125th Anniversary Model made in 2024.

Looks really nice! I wouldn't want to take any chance using any heat that would discolor the barrel or attached moderator. I've got a craft and hobby heat gun I got from Amazon for $11.00 that puts out heat in a tight area that I've used on other rifles with a loctited moderator and it works well. Just me telling about my experience removing a loctited mod off another brand of rifle. An expert I'm sure will chime in soon to help you out with this project!

@Dogowski gave great advice.
Easy to understand your caution- what a beautiful rifle!

Gorgeous gun sir! Come live in my country, no moderators allowed so you wouldn't have this problem
In all seriousness though I would try it without the mod and see if the noise isnt too bad, that way you wont loose any power if that matters to you? As mentioned dial the heat gun to a lower setting and go slow, get it warm & try cracking it, warm it some more & try again till it cracks free.

Slow and steady wins the race!
