HW100 silencer removal

[SpeedTripleR]

Hi all,

I have just got a new Weihrauch HW100 S and today attempted to remove the silencer to aid with cleaning the new barrel.
The silencer doesn’t seem to want to come off as I’d have expected it to. I can take the silencer apart, but this still leaves a cone shape on the end of the barrel.
I’ve tried heating it up but it won’t budge at all and I don’t want to force it as it’s going to put strain on the barrel.

Any HW100 owners experienced this and if so, how did you remove it?

I can’t think of any logical reason for Weihrauch to glue the silencer onto the barrel.

Cheers

Hi, as far as I know they just unscrew, if it's tight gent a firm grip and a quick twist and it should come undone.

I tried that while it just had the cone on the end of the barrel, thinking it’d just need a firm grip. After slicing my hand to bits on the exposed thread, I gave up.
I’ve tried using a rag over the end but it will not budge. I may try using mole grips but don’t want to damage the barrel.
On all my previous guns they’ve been hand tight and just unscrew.

Mine just screws right off.

Mine just screws right off.

Thanks for the reply. Didn’t think it was right. I’ll have to get the gun shop to take a look then. If they damage it, they can replace it.

If you disassemble the mod so only the cone is left you can carefully drill a couple of holes in it to locate a peg spanner, (if you have a peg spanner)) once reassembled the holes will be inside & hidden from view.
Another thing to try is a pair of "water pump pliers" or even a "stilson wrench" with a leather belt or similar to protect the mod from damage.

What sort of heat did you use ? could be it just wasn't hot enough to melt whatever thread-lock has been used on it, if you can hold it without gloves it's probably not hot enough

Since it's a new gun, I think that's the best plan.

I have never had, or known anyone else to have a serious problem getting the mod off.

I didn’t go to mad with the heat, but it was getting to the point of being too hot to hold. I don’t fancy drilling it though as the shop won’t touch it after that.
The gun is only a couple of days old so I think I’ll get the shop to sort it out. It’s their problem then if it gets damaged.

Thanks for the advice Mick

Sorry I missed that it was new, definitely back to the shop.

I would certainly ask the RFD to remove it for you rather than risk damaging it yourself.

When I first tried to remove it on my 100S all that happened was the barrel turned with the moderator. This is apparently quite a common problem with a simple solution.
You have to remove the air cylinder to expose a small grub screw in the action that locks the barrel in place. It is good practice to loosen this sufficiently to remove the barrel and remove any excess oil before refitting and tightening the grubscrew.

The barrel should be refitted with the serial number on the l/h side at the 3 o'clock/9 o'clock position, although some people like to index their barrel by rotating it and marking the point of impact when aiming at a single fixed point. They may then choose to fit the barrel in the position that shoots at the 12 o'clock point of impact.

If it is not getting unscrwed easily as it should then do not force it. The barrel of the HW 100 is held in place with a single grub screw under the action just where the air cylinder meets the valve. Trying to turn the moderator will turn the barrel and could cause damge. If the gun is under warranty then take it back to the RFD you bought it of an dlet them do it for you. If it is under warranty the you could take the barrel out and hold it firmly with some rubber gloves or rubber band and try and unscrew the moderator.

It’s going back to the shop tomorrow and if there’s any issues, they can change the entire gun for another one. This is only a few days old and not even zeroed yet.

Not having much luck really, as this HW100 was a direct replacement for a BSA R10 SE that’s had too many problems to list.

This will be my 6th visit back to the Airgun Centre in Rayleigh with problems with their guns in a matter of weeks!

Starting to think I’d be better off saving money in future and buying elsewhere, as you pay higher prices with them for the promise of lifetime warranty. If they can’t check a brand new gun over prior to sale, it doesn’t fill me with confidence down the line!

It's hardly the shops fault that the items they receive from the manufacturer are not perfect, with the exception of vehicles I'd expect pretty much everything I buy to be sealed in a box as it left the factory not having had a "middle man" tinker with it.

The threads on the rear section of silencer or the muzzle could have a tiny nib defect,locking the two together

At this point, if it's a new gun, the retailer should replace it for you, and take up the problem with the importer.

Can you try leaving the silencer in place and inserting a drinking straw to bypass the baffles? Pass the cleaning aid through the straw.
