Silencer check

[TechMec]

As a complete novice starting target shooting in my back garden this past week, I was plinking target print outs with my HW 95K to try to zero my scope.
After about 30 odd shots i was getting some close groups but then my shots started grouping consistantly off target about an inch below my aim point.
I was puzzled for a while as to why it was happening then realised my Moderator had worked slightly loose and affected my shots!
Just putting it out there if anyone else has this problem

Yep, happens more often than we care to admit, and is often the last piece of the puzzle that we check.

I recently noted that the accuracy of my FTP900 started to fall off. Crap, I thought, the reg's probably playing up, hopefully it just needs a pull through. I decided to give the barrel a clean, and that's when I noticed that the Rowan air stripper had worked itself loose and inched forward

Welcome! This works for me:
Unscrew the moderator and wrap a few winds of plumbers PTFE tape around the threaded barrel end, then screw the moderator back on. Should stop it from unscrewing itself. You might need a couple of attempts to get the right amount of tape on the threads.
Good luck

Some use an o-ring on the barrel and it grips the moderator .may take experimenting to find a o-ring that will solve it though.

After my 95k silencer coming loose a couple of times, I decided that it was going to get a good dose of red threadlock.

It hasn't budged since- just hope that I never need to remove it!

At least you spotted the problem quickly. The HW mod on my HW90k is a very tight lock up. Welcome to the forum

Light Bulb Moment!

Ah! that's why the HW90 moderator is bonded on - I'm guessing the gas-ram firing cycle would cause a standard threaded moderator to loosen and unscrew itself.
