Gemtech

What’s in your silencer?

One of my employees purchased a nifty little Snap-On Borescope, with a tiny lighted head the other day. Of course I commandeered it immediately for scientific purposes…

Let’s take a look at my old Gemtech M4-02. Purchased little over 7 years ago, it’s seen thousands and thousands of rounds. Most on 11.5″ guns. Some FA, but not a lot. A good amount of .22 as well. Plated and lead. Overall, a good amount of abuse.
I’ve recently started noticing that it just wouldn’t suppress as well as other .223 cans, so I became suspicious.

Now – the pics below are taken off my TV screen, I plan to buy a proper adapter to get the images digitally into my computer. Until then, this will have to do.

Let’s start from the blast baffle:

Nothing much to see, lots of carbon buildup.

 

Second baffle.

Moving on, the third baffle.

Far from round, an unbelievable amount of material built up around the edges. Interestingly enough, it’s all facing the muzzle. That leads me to believe we’re looking at jackets, or lead, piled up on top of each other along with a healthy bit of erosion.

 

And finally, the end cap.

The end cap has what I would describe as “the rolling hills of lead” built up around it. Seems very tick, some spots a bit blue in tint, and very smooth, compared to the jagged mess we saw earlier.

Dr. Dater from Gemtech has informed me that they may be able to rebuild my can, which I am eager to have done.

After talking with Stalking Rhino about rebuilding it or even converting it to a dedicated .22 can, I’ve decided to hold off, as the work, which will undoubtedly be top notch, is inherently cost prohibitive compared to the purchase price of the original can. But that’s part of the game.

Upgraded Gemtech Outback I – back from Gemtech!

As I mentioned in a previous post, I had sent my Outback I into Gemtech to get upgraded.
I had opted for a Titanium blast baffle and the rest of the stack in Aluminum.

Due to a mistake at Gemtech, after 4 weeks I received my unit back….un-touched! Neatly sealed in a sleeve with a takedown tool, but un-touched, un-cleaned, and still unserviceable!

After a phonecall with Gemtech, Joey and Kel took care of the return shipping for me, and offered me a free shirt or pouch for the inconvenience. I declined.

Two days later, when my can was delivered at Gemtech, I received a phonecall from Dr. Phil Dater at Gemtech, apologizing profusely for the mistake. He offered to upgrade all my baffles to Titanium. I was hesitant at first, but Dr. Dater assured me that he would be happy to do so, so I gave in at last…

Here it is, disassembled, with the Ti baffles and Aluminum takedown tool.

The new endcap, removable with the tool for disassembly.

The mounting side of the can. The only thing they didn’t replace on the unit is the tube itself.

I’ve done some limited shooting with it, but it was hard to tell how loud it really was, as I shot it indoors. It does seem quiet, probably quieter than it was. So far, I’m impressed with the upgraded unit, and I’m very impressed and pleased with the way Gemtech took care of me when the mistake was made.

 


Gemtech Outback Upgrade.

Kel from Gemtech recently pointed out that they now have the “Gemtech – Have it your way” upgrade program for the Outback and Outback II line of .22lr silencers.

I’ve decided to send mine in, as it is very old, and not user serviceable. It also doesn’t quite compete with the modern cans anymore, a recently purchased YHM Mite was quieter than the Outback.

The options Gemtech offers in the “Have it your way” means that the owner has a choice in materials for the blast baffle, and the following 5 K-Baffles. The choices are Aluminum, Stainless Steel and Titanium. I chose for a Titanium blast baffle, as it takes the brunt of the blast and crap, and aluminum baffles for the remaining 5 K’s.
Stainless steel is a nice option as well, as it is easy to clean, but it is also heavier. And that is less desirable with a .22 silencer this size.
The Outback weighs in at 4.3 Oz. at the time of shipping. It would be interesting to see the weight change when I receive it back.
I think my choice is a good one. The can will go out in tomorrow’s UPS. Look for an update once it comes back!
