New dm80 compact mod

[Jager SA]

As for the seperating on the threads I havent come across that, so will not comment. But I have seen Wildcat and an A-TEC go pop on the range, neither filled me with confidence.


Im big enough and ugly enough to take any verbal drubbings that come my way, but being polite doesnt hurt anyone does it?

I think we have all expressed our opinion at some point, I am not a professional stalker, nor have I yonks of experiance like some of our members, but I think that I have something to offer up it is a public forum after all.


No hard feelings,

Ive sold a large number of A-TEC mods, never once have I heard of one going POP, can you back up your post with evidence of this, be useful to know as to why it did go POP?

Thar,

Briefly before re-locating to Darby. Originally worked on the Gem before being sponsored for an engineering degree.

I gather it's not like it used to be...........i'm assuming you worked there to? Impact driver hidden in the pocket???

Hi Marc

I worked at one of the Derby sites in the late 80s, RB211 V2500 and Tay engines, at that time East Kilbride did a lot of the fabrication and pipe work IIRC.

Still remember my license stamp number C-90.

The A-TEC was an old model, but was pretty new at the time.

Basically he fired the shot (from prone) and I was at the other end of the firing point, I thought he had hit a dandilion close to his muzzle becuase thats what it looked like, a puff of white things, I wasnt really that fussed so got on with what I was doing. Anyway, a minute or two later and someone does the whole "STOP STOP STOP" jobbie, we allget rid of clips and bolts and look at the RCO, turns out that the moderator was hanging at a rather funny angle . Everybody gathers round and theres bits of moderator 80m down range .

He took it up with the importer (could have been the maker, cant remember) at the time and I think that they sorted him out with money for something new.

PS Cant post the owner becuase I only know his first name

PS2, Jager - I dont know the real technical detail, it was quite a while ago and I am not in regular touch with the guy, it wasnt really any of my business - it just made me think I dont want an old A-TEC.

The only problems I have ever seen with any fullbore mod has been when folks have used them on their rimfire rifles first, then screwed them onto their fullbore and got an ignition from all the unburnt rimfire powder and grease within.

There have been many claims about this fullbore moderators breaking up, but I have never seen one and don't know of anyone personally who has had one do so! But while shooting with friends I have seen two spontaneous flashes after using rimfire primed moderators. Both moderators survived, and they were a PES Scout and a T4.

Sam, there should be a log of the incident at your range, perhaps you could PM Jager SA with the details.

Ft,

Next time I am at the range (we only meet a few times a year) I shall see what I can dig up, I will also ask said chap - I wouldnt want to be mucking about in his affairs too much.

Sam, I only ask as ive put the old A-TECs through their paces (Tried blowing them up on a 300WM) and you wouldnt believe what they will put up with, my only thoughts are user error rather than manufacturing fault. I have had a few back where people just dont read the blurb or do silly things.

Could have been that I guess, not tightening the what-sit-called or greasing the brass mongoose

Hi Flytie, I had a PES mod separate on a .300 win mag and personally know of one other that did this. Moderator outer went off down range like a mortar round and the rifle came back in my face. The problem was due to differential expansion at the junction of the outer and the threaded spider. I cn honestly say I though I had had my chips when it happened. Feeling gingerly round your face to check for broken bits/gashes etc while profoundly deaf is no fun.

i only offer this experience as an example. I am assured it has happened a good deal.

With regard to the older A-TECs - my guess is that it could be to do with the threaded bushing: the way it was threaded, when you tighten the mod onto the barrel, the bushing unscrews itself if you're not careful (the Jager SA version fixed this by reversing the internal thread), this happened on mine, you need to loctite it on or in my case one turn of PTFE tape... So what probably happened is that tightening the mod on actually made the internal threaded bush unscrew, to the point where it disengaged, the result would be that mod would hang off as described, if a shot were also to have been fired whilst misaligned, then you'd be putting a bullet through the baffles...

As I said: just a guess!!!

That is a fair point Mat, our enhanced version is much better, better materials and ironing out of weak areas, one of which you have mentioned, not only that it is the cheapest mod on the market and great value.

Gareth, I am pleased to hear you are OK! I have heard many stories, but only your experience is personal. All the others seem to be, "a bloke down the range/on our shoot/ I heard of". I hope you were well compensated and suffer no long term effects.

Saw a T8 peel at the 100/200 yd range as Bisley. A loud noise, a commotion and the moderator looked like an opened can of beans.

More recently - during a short course being run by the SW Scotland branch of the BDS, held at Jackson's Parton range an old boy named John brought along his new pride and joy. It was a re-worked rem 700 in 308 and topped with an A-Tec mod. Rifle and mod were supplied by South Yorkshire Shooting Supplies. Anyway shortly in the detail, i and others are standing behind the shooters when theres a loud bang, the moderator launches itself 20yds down the range and old John turns around in confusion to show us the blood running from his eyebrow.

The real eye opener was when John retrieved the moderator and attempted to screw it back on with the intention of continuing firing!
Now he moaned that it was obviously the fault of South Yorkshire because the threads were now stripped which was ********. In my opinion he didn't put it on correctly.

Point is that i got a chance to inspect the moderator after the incident and with the exception of an enlargending of the hole to on-side there were no other obvious signs of damage (not that i'd ever contemplate using it).

Interesting post. I know of a few mods that have been returned due to user error..."please read the instructions before use"...the best one for me is when someone used his 6mm on his 30cal rifle... now some would say it would have bu**ered the mod...it didnt all it did was open the baffles to a ragged 30 cal dia... Dont try this at home though!

Hi Kevin

A meet up in D&G would be great; I would look forward to meeting some of our newer members.

A little history.
When the original A-Tec moderators were imported into the UK some individuals made a great deal of fuss on the internet forums about the baffles fire cutting, the original moderator had a primary stainless steel baffle but even so they give the importer a very hard time about the secondary baffles fire cutting. Anders (the owner of A-Tec) was not interested and said the fire cutting was acceptable. In the end the then importer offered additional stainless steel baffles at his cost.

My own view is that the individuals involved had at least impart an ulteritive motive in all there complaining, never the less throw enough mud and some will stick I guess.

The great thing about the site is in a few months you guys with the alloy ones will be able to put photos of your baffles after a few hundred rounds down them and everybody will be well informed as what to expect, there for make a informed choice.

Hi
a one sided view i see and one that could only come from a mate of the then importer.

The facts are the moderators where sold with a 2 year warranty and the baffles lasted a few months.
they where all so touted off by a partner of the then importer as being able to take rapid fire over a long period of time and had been subjected to hours and hours of intensive testing.
The truth is none was done and the baffle failure raised its ugly head. some people say it was a few people steering the **** but i know of many many dissatisfied customers in my area that brought one and the baffles failed very very early on.How big of a problem was it i nether know nore care but self opinionated people should stick to facts and not muddy the water with tails of conspiracy's,just because their mate sells them and now is marketing a copy of one.
the truth is out there you just have to have a open mind and some fact's

The proble i find is the moderators that can be so called field stripped are a recipe for disaster get a good solid mod and when its done throw it away .No risk of the mod blowing up.

 

[camathias]

Never understood why anyone would want to strip a mod wile out shooting. or when they get home for that matter.

Bloody good point! To be honest if its cheap enough it can be sealed and used to death, then thrown away! Im working on it the CNCs are working as fast as they can...!

Human nature...not good really. Newer models will be welded shut so no need to strip.
