I have seen the exact same thing happening at the range. And it was definitely the oil in the mod. It had just been sprayed the night before.

The reason I now also have a F&D mod is that you can open it easily and scrub or wash the crud off on the inside. I am hesitant to spray any oil in it as I am certain that this will increase carbon buildup, burning temperature and ultimately material fatigue. After all, oil will burn and leave residue.
The first thing I did to the new mod was to open it and remove any grease from the inside. Interestingly enough there were lumps of grease on exactly those edges that show signs of deterioration on some of the pictures on this thread.
Unfortunately the F&D moderator for my .223 cannot be dismantled. The one for my .308 does unscrew however.
When I bought them I was told that the F&D did not advise taking any of them apart.
 
I don’t normally spray my mod through as I typically fire only one cartridge per stalk :cool: This from a colleague is at the back of my mind........View attachment 199626
I once had that after cleaning the rifle but give the mod a quick spray after every outing (if it's been fired that is) and sit it on its end to drain

Odd as the F&D website says one of the benefits is that they are easily dismantled for cleaning!

Is the one on your .223 stuck shut? Wrap a rag round it a soak the rag in WD40, leave for 24 hrs and it should open

Thank you Slider,
I bought from Ed B who said the rear section of the smaller moderators was bonded to the unit - apparently the Europeans get sealed units. When I commented on this and thus the inability to clean the sealed unit Ed told me that the Europeans don't take them apart as they are self-cleaning.
 
Interesting post about A-Tec moderators catastrophically failing up on FB. Interestingly, other makes creep into the thread and there is a picture of an F&D which peeked my interest as, unlike the others which are failures of the baffles obstructing the bore (the original concern of this thread), the F&D appears to be a “pressure” failure of the outer casing. Not the failure mechanism alluded to earlier on in this thread and most likely to be a “quality“ or external damage initiated failure. First picture below is the F&D, the others of other well known makes. As @Ronin states earlier in this thread, mods live a hard life and should be seen as consumables - it’s not rocket science if you excuse the pun.

Jeez, that’s a bit scary.
I have an ASE S5 mod on my .308, it tames the noise and recoil really well but it’s a bit heavy. I have given quite a bit of consideration to swapping for a newer lighter mod, this post has convinced me not too bother.

I’d eat my hat if anyone has a picture of an S5 that’s blown up!

Consumable yes, in an appropriate time frame, measured in years not weeks or months, not showing corrosion after minimal use and good maintenance though. That one of the F&D looks worrying/intriguing! Wouldn’t want to have been on the receiving end of the bit that flew off!
 
You would think the company who produce these expensive moderators should come forward with an explanation of the numerous failures on these mods.anybody heard anything??
 
Crikey!! Anyone standing either side of that could have been blinded by what becomes in effect a “frag” grenade. Surely if this is happening even infrequently there should be at least some duty of care response from the manufacturer? As per the WH earlier post I have T8s and S5s and long ago decided to sacrifice weight for strength, each have many, many rounds through them on the range and a squirt of WD40 immediately on getting home seems to have helped their endurance. I also routinely borescope them and thus far have seen no issues.

I had a T8 on my 7mm-08. Bit heavy, but solid - or so I thought. After not all that many rounds (though a few years, admittedly) it started blowing at at a seam. I have since been told "that's where they always go". I replaced it with an F&D. So far so good.
 
I’ve had a ASE Jet Z for over 10 years, thrashed the living god out of it, probably had 4000+ rounds through it (99% Copper mind you!🙈😂)

never cleaned it, just take it of to store it.

a lot to be said for a heavy old lump of a mod.

I’m beginning to think that In the quest for lighter moderators to please hunters corners are bing cut!

I think it will need re-zeroing now
 
Hmmm. As above then WD 40 really must make a difference - my initial T8 is still going strong after many thousands of range rounds on 308, 6.5 and .222 with absolutely no signs of a problem. Just a quick spray from both ends as you are cleaning the gun, simples.

How about a first-shot-deviation and a cloud of smoke?
 
Let me phrase it differently, would you take it out stalking after it‘s had its WD40 treatment?
Not only have done since for ever but will be doing so most every day for the next 10 days in Scotland, please god.
Piqued my interest now - Is there any hard evidence that a micro-thin coating of said penetrant impacts on accuracy/velocity? I have never experienced it.
