And Still Yet ANOTHER Silencer Arrives...

[mrbulk]

...this time from Geo. The new unit is his latest iteration with a steel threaded insert within the attachment end.

It is 6" long by 1.2" wide, slotting neatly in between the Geo Short and Geo Hunter. It will be his standard length for now to keep things simple. Weight is now 1.8 oz. (vs. 1.7 for the Short and 2.3 for the Hunter).

The bulk of the unit is still made from polymer materials, but Geo has upgraded the overall design to be less prone to cross-threading and allow for ease of cleaning. Geo says:

"My direction has changed since the last time we spoke. I've determined for now that I'm going to make polymer LDCs with steel threaded inserts. This allows the design to be very lightweight, very affordable, and have strong metal threads. In addition, I'm able to buy half of my materials from local businesses and everything but the wrap is made in the U.S.  As with all my prior designs, no foam, felt, or other disposable sound absorbing materials are used - it is all flow dynamics at work. To clean, simply plug the end with a 1/2-20 bolt on one side, fill with 91% rubbing alcohol or denatured alcohol, and let it soak for 5 minutes. The oil and lead dust will dump out with the alcohol, any residual alcohol will quickly evaporate."

Of special interest is his reference to the, "...foam, felt or other disposable...materials" nature of some other units, meaning like on his other units, there is nothing to replace, maintain or loosen up.

The internals have also been further updated and hopefully will be as quiet as (or quieter than) his longer Hunter version that was recently tested.

So there will be another test a bit later, this time with a more powerful straight barreled gun that can also be detuned, so that hopefully I can also do comparative testing through the same gun except detuned further down (sub-12fpe?) to see which silencers are best at handling Both low- and higher-powered airgun blasts.

Stay tuned.

In the photos below you can see the relative lengths between Geo's Short, Hunter, and this new medium length unit.

Also visible in the photos is that new steel threaded insert, as well as the cleaner exit hole of the new unit which makes it neater looking IMHO.

Charlie, nice new in inbetweener! I'm sure it will be be quite efficient in quieting down any PCP. I like that he likes to use non disposable materials which makes it easy for cleaning.

Thanks Randall.

By the way, Geo just got back to me and the projected price on this one will be only $38(!) and he expects to have his site back up on Feb. 1st. Everything shows out-of-stock at this time.

Also he will offer .177/.22 as well as .25 sizes.

I wish that you would do these reviews over at air gun nation so you could show the internals...

Yeah, unfortunately the internals on most units are permanently sealed anyway and could not be viewed unless destructively torn apart, plus some of the makers prefer that their proprietary designs, which they worked hard to develop, not be divulged.

But feel free to link these reviews if you wish, in fact it would probably be much appreciated.

Another interesting point about Geo's monocores is, just looking at the 'guts' if removed, is not all that interesting or informative.  All the interesting design work is on the inside and not truly accessible without cutting the core in half!  Suffice to say, unless you have a 3D printer, you will be unable to duplicate Geo's cores anyway.  I should know, I've seen the insides in great detail and have a fair amount of machining ability, yet I can't make his monocore in one piece and probably not in a multitude of pieces on machinery that works on the removal of material. 


Geo has also put years into his designs, it would be unfair to publish his designs for others to try to duplicate.  This man makes his living with these 3D printed designs, would you really want to take food out of his family's mouths 'sharing' his designs?


Nope, I would be happy to pay twice the purchase price for his designs, they are highly effective (from my testing) extremely light weight and cost a fraction of the competition.  I once tried to explain to him he could charge considerably more for his products but he said he'd rather keep the prices as affordable as possible so 'joe average' can buy them without hesitation.  It appears his business model is working for him.  God bless him for helping out the average working man who may not have a $2K airgun or $200 LDC's but wants an affordable, effective LDC to keep his airgun quiet enough to not bother anyone.


Looking forward to the testing results, I may have to update my Geo LDC's if it works even better than the others!
