    Can those of you who are running one or have one being built chime in with the information about what kind of LDC you are running or having built. Please include the dimensions and maker of the LDC and if you have it already how you like it?

    I really prefer a Reflex Style LDC to keep the impacts length as short as possible. I have even considered having cone style “Air Disruptors” made of Aluminum, Delrin, or even 3D printed that would fit snuggly inside the front of the outer shroud.

    I truly want Neil Clague to build me a Reflex Style LDC however, our communication through Emails have not gone smoothly, not to mention Neil has reservations about the complexity of a building a Reflex LDC for the Impact. I, being fairly new to PCPS and extremely new to any modifications to them, doesn’t help the situation. At this point I am left scratching my head as to which direction to go. There are very few examples I have come across to get any clear idea what is possible. Any help would be greatly appreciated!!

    If this is Jason?  I answered numerous questions for you and gave you various options for the Impact including a 2 piece shroud which was what you finally told me you were interested in and you were going to get thread sizes and dimensions from the maker, I have not heard back from you since, so please do not post that the e-mails did not go well, you were given all the options and prices and thanked me for my help and apologized for all the questions because you are a newbie. You asked me about a Reflex style which is not an option with me unless the factory shroud is removed, I told you that if you removed the factory shroud the most effective way to go would be a full shroud or in your case where you wanted the option to keep it short, a 2 piece shroud with the LDC removable. I am somewhat amazed by your post, after I answered countless questions from you and gave you all of your options and you told me you would get back to me when you had the information I needed, ! Neil.

    Neil,

    You are taking my post way out of context. I have been very up front that I am new to PCPs. What is nice in the powder world is you can see pictures of what you are buying and discuss the pros and cons of each manufacturer’s products. I have only seen 1 person with a Hagget moderator on there Impact or those who promote FX products or live outside the US have the Original Impact moderator. Everyone has said the same, the Impact is much quiter with a true Moderator on them. That is all I have to go by here besides the state ment made that your LDC’s work the best.

    I just sent you an Email offering to send you my gun when the time comes and what I am looking for in an LDC. I hope you can build me something to show others so they know what they are going to end up with.

    If you’re looking at getting a standard 1/2 UNF moderator that can fit either 0.177 or 0.22 cal guns, I’d suggest you look at the Weihrauch sold from Penchetta or you can buy generic moderators from wolfairguns.com. I own both types and the Weihrauch is better quality and works better but costs more. I use them on my Air Arms and BSA rifles. I don’t own an Impact but if the barrel you have is already threaded and you want to remove the FX shrouds to expose the barrel so you can screw on the moderator, that may be an option. And the best part is you don’t have to ship your gun to get the moderator attached. Just my 2 cents.

    Thank You, this is the type of conversation I was trying to get going. I have no problem sending my gun to Neil, I would NOT send it to AOA. I would buy one like you are saying. YES, the Impact barrel is threaded 1/2×20 UNF. The sliding shroud is just not doing it for me and by the sound of the amount of inquiries for LDCs for the Impact, I am NOT alone. FX dropped the ball on that stackable moderator originally shown on initial pictures of the Impact.

    I’ll take some pictures of the moderators I have when I get home from work so you can get an idea of their dimensions and see which ones you may want to buy.

    FX didn’t drop the ball because they didn’t build the gun to your specifications. I wouldn’t change a thing on mine. It is a 30 cal and plenty quite for me.

    FX shooter the problem is you really do not know what you want, you kept talking about a Reflex moderator and then told me you wanted the quietest possible, well that is not going to be a simple screw on LDC, Weirauch or any other make, it requires a 2 piece shroud to make full use of all the space around the barrel as well as the space in front of it. MY problem with you has been your lack of understanding what the correct terminology is and your not knowing what you want for your gun. I have no problem with you buying a Hugget or Weirauch or any other LDC, but I can only help customers when they know what they want made or what they want to buy, all the best, Neil.

    I skirted around the subject of a reflex-type moderator for the Impact with Neil in another thread previously.  What little I know and what he explained is correct, you either need a one piece shroud that screws on the end of the barrel and screws on flush where the barrel comes out of the frame. Or you can use what I have, a Daystate 1/2″ 20 UNF  Airstream moderator that when screwed on the barrel will need a short shroud that exhausts the air rearwards in the space between the shroud and the barrel.  I do not know however, if the space is enough inside the shroud to eliminate the sound to Neil’s liking. May need some holes drilled near the rear and felt stuffed inside. etc…  The Airstream when screwed on is actually shorter by about a couple of inches than the end of the Impact’s CF bottle.

    So a custom made LDC screwed on the barrel extending to the end of the CF bottle may add enough space to reduce the report.  May need to make it a bit longer. I am not an expert, but I think if the combined space is enough to diffuse the volume of air per shot, making the LDC itself is not that complicated. What maybe complicated is to make one that would be equally effective for a .22 and a .30. I think the opening for a .25 size works for a .22, but the opening for a .30 size may not work for a .22.    Neil should be able to come up with an ingenious design that does not require too many extra parts to be swapped out between calibers.  I only have the .22 measurements, and do not know what diameter/length .25 and .30 size shroud/barrels are.

    That is great that you are happy with it. However, there is a reason that the custom LDC makers and Dealers like Jim at Precision Airguns are receiving “alot of inquiries” for an LDC or Stackable Baffles for their Impacts. Also, look at what those who have a direct connections to Fredric at FX are running (Ted from Ted’s holdover and Earnest to just name a few).

    I would wager to say there are more that are unhappy with the telescoping Shroud sustem then are happy with it. Wait until one of the O-Rings in it breaks and seizes up the shroud not to mention you are grabbing your BBL everytime you deploy or retract the shroud, Not a good thing. Hey, what do I know, I am a NEWBIE to PCPs, but I have one hell of an NFA collection and I understand Suppressor Dynamics. Not having any baffles inside that outer shroud requires you to use a tube 2x’s as long as one if it had baffles and would be much, much, quiter.

    Your exactly correct and this is what I have been getting at since the start. Not having any examples is where problems arise. Also, the regulator adjustment knob comes into play. If I choose to buy a .30 it will be a little ways down the road. Hell, you can’t even get magazines for the it. I would have another made by Neil, or tryout some other alternatives. It is not a cost thing with me, it’s does it achieve what I want. I mean, 3 baffles inside the end of the tube would be better then open space. Hair curlers would be better then nothing. What is frustrating to see is that Fredric is/has been handing them out to “certain people”, but not offering them for sale to us.

    I have seen the pictures of yours. It demonstrates how short it “could be”.

    So here are the 1/2 UNF moderators I own. The Huggett came already included with the Brocock Compatto, not permanently attached, but I didn’t buy it from AoA. 
    I’m not sure you can buy the Huggett on its own without sending the gun in to AoA – only known distributor of the Huggett without buying the Compatto as well.
    Both the Weihrauch and Huggett can be field-stripped. The other one appears to be sealed from what I can tell. Also, the paint job on the wolfairguns one is average – the paint can flake off easily and doesn’t appear to be cerakoted. Hope this helps. 

    From top to bottom: 
    wolfairguns.com branded $42 shipped
    Weihrauch $125 shipped
    Huggett – ? price

    This is what I was hoping to see, different examples and hear what people think of them. I am going to go with a Neil Clague at this time, I have heard his are the quietest, best Quality LDCs, and the Weihrauch is next. Going to find out. Thank you for posting.

    Let us know hoe the Huggett works with the larger end caps? Also, which one you prefer?

    Which do you prefer best? I am used to paying ~1k for powder burner suppressors.

    Anyone have custom examples out there?

    The Huggett was used only on the Compatto so far and it, in addition to the shroud with baffles, makes the gun very back yard friendly. I’ve used both the Weihrauch and wolfairguns moderators on both my BSA R10 Mk 2 and my Air Arms S500’s and the Weihrauch is quieter on both guns. That’d be my first choice in between the two. With the Weihrauch attached, all I hear is the mechanical click made by the gun firing. Better sound moderation for a lot more money. I hope to do a decibel test between the moderators on but the issue is that different brands and models of guns will vary in sound output so YMMV on your FX gun. I’ve realized that with airguns, we here in the US are often our own guinea pigs as there is no easy access to brick and mortar stores to test out and handle the items we often buy online.

    Same issues with powder burning Suppressors. Tone comes into play. Also, shooters ear (especially on AR based semi auto carbines and SBRs) and what it sounds like downrange..

    Don’t forget the compato is only shooting 27 ft lbs. Can’t compare a gun shooting 10 ft lbs more.  Shroud plus moderator equals most quiet.

    I’m in the process of ordering a LDC from Neil, and apparently FX has different threads on the end of their retractable shroud.  

    If anyone has measurements or know of the thread/pitch for the different end caps, please post up.  

    And BTW, Neil is a consummate professional!

    FX shooter could you please check to see what thread size and pitch is used on the end of your factory shroud for me, it would appear that FX has done the same with the Impacts as they did with the Wildcats, they have put them on the market with different thread sizes and pitches? Many thanks, Neil.
