apbuild Posted November 7, 2006 Report Share Posted November 7, 2006 Dropped my sako .308 off to the gunsmith on Saturday to get the barell screwcut and the AU S5 suppressor fitted and proofed. Got a trip to Bisley on November 25th so I am looking forward to getting it back and zeroed, ready for some winter deer stalking. Anyone got one of these moderators fitted to a .308 already? If so, I would appreciate feedback. Rob. Quote Link to comment Share on other sites More sharing options...
mry716 Posted November 7, 2006 Report Share Posted November 7, 2006 I tried one on my Rem700 and there was little difference from a T8. BUT and its a big but the threading is far more critical than with any other silencer as you need 5/8" of shoulder that is a perfect fit with the inside of the boss on the silencer so as to hold it in perfect alignment. There must be NO sideways movement whatever when you first slide on the silencer and the thread should start smoothly. In fact you should have difficulties in sliding the silencer on the fit should be so good. The thread and shoulder and bore all need to be in the same plane and it does add another factor to making sure any job is good enough.

Dunkield Posted November 8, 2006 Report Share Posted November 8, 2006 As I have said before ad nauseum, IMHO ASE mods are the future - just look at how many T8's are appearing in the for sale ads on forums, never saw that before I was at Bisley (how many sentences start like that!) and a guy had a a Heym(?) break barrel single shot rifle with a 308 barrel fitted with one of these. I wish I had my camera as the barrel was cut so short it was almost pistol length, but the mod did it's job and he said it was very comfortable to shoot. he shoots in dense woodland hence the barrel length. He ten slipped that barrel off and slid a .270 barrel on, again with an ASE and fired a few more shots, it certainly seemed to calm that round down. I asked him what he thought of them, as most people seemed to rate them, and he said all of his guns had T8's and there all being sent up Jackson Rifles to have ASE's fitted intead as and when he gets the funds to do it. Coincidently, also at Bisley, at a running deer day, another shooter who was using what can only be descibed as state of the art equipment (RPA + Nightforce etc) had one and was raving about it's performance. That one was fited to a 6mm BR. They are small, but are not light. If I was to get one I would get the barrel chopped at the same time, as they don't reflex back, and as MRY has said fitting is a specialised task, as they only have a single point of contact.

I have to say that seeing a picture showing the amount of material removed so has this mod can be fitted would put me off having one . Compared to a T8 they are more expensive but due to my Fabrication Experience I like the 2 points of contact with the barrel the T8 offers which IMHO is a more superior design and also a reason behind no change to zero when the mod is removed and re-fitted ..........you can aslo make a nice Brass end cap for the rifle when the mod is'nt required thus keeping a cosmetically pleasing appearence . Sorry I can't answer your question Rob other than to say your paying a bit extra for your own personal Ear protection . Quote Link to comment Share on other sites More sharing options...
mry716 Posted November 8, 2006 Report Share Posted November 8, 2006 "I have to say that seeing a picture showing the amount of material removed........." Not really as you just buy a silencer with a thread size appropriate to your barrel diameter. You need a shoulder on your barrel for a T8 / T4 and this is no different except for having the 5/8" bearing surface prior to the shoulder to provide perfect alignment. The silencer sticks out no more than a T8 from the end of the barrel and is lighter in weight so there should be no problems. Remember we have lived with 'accurate' rimfire silencers for years that stick out much further and are usually subjected to far more abuse.

mry716 Posted November 9, 2006 Report Share Posted November 9, 2006 BUT Whatever the picture shows the point is if you have a barrel with a muzzle around .6" diam you thread 1/2" UNF whereas if the muzzle is .85" diam you could choose the 19mm thread etc etc You then only machine the minimum amount of metal from the barrel as well as the thread (and protector) being cosmetically more pleasant when the silencer is not fitted. Surely this should be a factor in the choice for all make of silencer as the T4/T8 also comes in a multitude of thread sizes yet folk usually seem to choose 1/2" AF because their rimfire is threaded with that size.

deadeye ive Posted November 9, 2006 Report Share Posted November 9, 2006 It's not the thread size that is the issue here ,it's the further M/Cing required past the thread to create a parallel sleeve (About 1" long I think )with a further or secondary shoulder which is what I am refering to Quote Link to comment Share on other sites More sharing options...

mry716 Posted November 10, 2006 Report Share Posted November 10, 2006 Unfortunatyely that is a somewhat unsatisfactory job. The guide portion of the moderator has been removed and the thread only left. You will have problems with such an installation. There should be only one shoulder that at the end off the guide. Which may be nearing an inch in length but need only be cut 1/16" into the barrel surface if the correct diam thread is used. The thread on the silencer follows the guide and is basically the same diameter ie no shoulder. Quote Link to comment Share on other sites More sharing options...

Surely if the moderator threads onto the barell and is secure once on, and in perfect line with the bore, the thing is going to work just fine. Any fitting done by a competent and skilled gunsmith should be carried out and then proofed afterwards to manufacturers specifications. Rob.

It is not just my own hearing protection that I am interested in. The woodland which I stalk is surrounded by villages which I do not wish to disturb at 6.00am with the sound of my rifle report. The target shooting at Bisley is not a consideration for me because I will still have to wear ear defenders. One of the guys in our rifle club shoots a Remington tactical with muzzle break. Now that is an anti-social weapon if you are prone next to him and he lets rip. Finally, I feel that £320- fitted and proofed is not excessive bearing in mind that: 1. I can stalk and shoot without ear defenders, so being able to hear all of the woodland sounds around me. 2. I will not be causing a noise pollution to villagers surrounding my stalking rights. 3. Moderators have been proven to reduce recoil and even accurise a weapon to a certain degree. 4. The moderator in question can be removed at any time, if I so wish and a thread protector (which i have ordered from the gunsmith included in the fitting price above), put on to restore the rifle to it's original state, in a manner of speaking. Cheers for all the input to this thread. Rob. Quote Link to comment Share on other sites More sharing options...
mry716 Posted November 10, 2006 Report Share Posted November 10, 2006 I am afraid I don't understand a word of what you are trying to say mate! Rob I am sorry if my explanation was insufficiently clear for you to understand so here is a photo. The moderator is made with a sleeve that guides and holds it in perfect alignment with the bore BEFORE you start to turn it to thread it onto the barrel and screw it down to the shoulder on the barrel. It should be a tight fit on the sleeve and without virtually any sideways movement. The photo you show indicates the person that fitted the moderator chose to remove the guide and just thread the barrel without turning the barrel to fit perfectly into the sleeve of the moderator first.

deadeye ive Posted November 10, 2006 Report Share Posted November 10, 2006 Now we're getting warm .........The example I have seen must've been a varmint barrel . Rob I see your point with noise pollution and agree ,I was just saying for a alot less expenditure you can get the same result with cheaper alternatives . I just think the more contact a Mod has with the barrel the better and as Mry says the sleeve is missing on the example shown .........good luck Quote Link to comment Share on other sites More sharing options...

JohnGalway Posted November 10, 2006 Report Share Posted November 10, 2006 Mry716 is quite correct. In the March 2006 issue of Shooting Sports on page 47 in Gear Test they review an ASE UTRA AU Jet-Z COMPACT (in nature but not in name ) I hope they don't mind me showing a portion of the particular page to help in this discussion. As you can see the sleeve on the moderator in mry's post runs onto the thinned portion of the barrel in the picture behind the thread to give extra support, then you start screwing it onto the thread. -------------------------------------------------------------------------------------------------------- Since posting the above I came across a Gear Test review of the ASE UTRA S5 again in Shooting Sports May 2006 issue page 26. It doesn't show any exposed thread on this page, but looks an awful lot like choke its pictures from what I can see. Until someone more knowledgeable comes along I'm shutting up Quote Link to comment Share on other sites More sharing options...

Cheers for that MRY! I see exactly what you mean. (I guess as Vinnie Jones once said, ''Do you want me to draw you a picture''?) The piccy you posted shows quite a pronounced guide before the screwthread actually starts. When I took my brand new AU S5 from the box I am sure that there was no such guide. I wonder if ASE have altered the design recently, or is this a different model of Supressor? Rob. Quote Link to comment Share on other sites More sharing options...
dunganick Posted November 11, 2006 Report Share Posted November 11, 2006 i have seen one of these before with no 'guide' section. So prehaps they offer different models, or removing this guide has become common practice (not suggesting that makes it ok as surely should hte moderator be worked on it will require reproofing which could pose a problem for those of us who dont proof after screw cutting) Quote Link to comment Share on other sites More sharing options...
mry716 Posted November 11, 2006 Report Share Posted November 11, 2006 Perhaps we are at slightly cross purposes. There is a range of ASE silencers and the AUS 5 is one of them - actually the latest addition that is not yet on the internet site. Some of the rest of the range are very similar in appearance but do not have the external 'guide' so it could be that others you have seen or even the one you have is not a '5' but another in the range. If you look at the magazine picture the model shown has an internal guide but the same requirements for machine tolerances apply. I replied with the comments I did on the basis a picture of a '5' was purportedly being shown. http://aseutra.fi/english/index.html Quote Link to comment Share on other sites More sharing options...
choke it Posted November 12, 2006 Report Share Posted November 12, 2006 if you look close enough you might be able to see the proof marks but this ase might be differnt to the other i'am not sure which one this is Quote Link to comment Share on other sites More sharing options...
mry716 Posted November 12, 2006 Report Share Posted November 12, 2006 I would lay £25 on that being a '5' that has been incorrectly machined, ie the guide has been removed, as it looks identical to the picture I posted of one as supplied. The proof marks show the silencer was proofed with the rifle after threading the barrel and that neither showed a failure with a proof charge. The Proof House would not consider the way it the silencer was fitted as long as the thread seems 'acceptable'. Quote Link to comment Share on other sites More sharing options...
deadeye ive Posted November 12, 2006 Report Share Posted November 12, 2006 -------------------------------------------------------------------------------------------------------- That's the one John ...............Thanks mate ,saves Dougy havig to look it up Alot of barrel material removed there so I'm not surprised if a Gunsmith removes most of that locating sleeve first Quote Link to comment Share on other sites More sharing options...
mry716 Posted November 12, 2006 Report Share Posted November 12, 2006 No ! The thing 'wrong' here if you are concerned about the amount of metal removed from the barrel is the size of thread chosen for the silencer. A silencer with a larger diam thread would have necessitated removing less metal from the barrel. There is quite a wide choice available for each and every model. If the manufacturers have provided detailled fitting instructions I assume that they have done so after considerable research and for an individual gunsmith to consider he knows better I find unacceptable unless the customer agrees to having the non standard work done and invalidating the warranty.
