15-22 suppressor

dullh · Jul 29, 2014

Gonna take the Form 4 plunge. Not going the trust route, for I have a Sheriff that has no problem signing off on suppressors. Anyhoo, a local dealer has a Gemtech and, since my 15-22 has no muzzle device, will thread my barrel for free upon purchase of the suppressor and clearance of ATF paperwork.

Questions:

1) Is the Gemtech a good one?

2) What will the suppression level be if I keep using my favorite ammo, the CCI Mini-Mag? Can I keep using this ammo or will I be stuck going to subsonic ammo for maximum suppression?

Discuss.

I use the Sparrow, so can't comment on Gemtech.

Must use subsonic for maximum sound suppression. With high velocity ammo, such as Mini-Mag, you will still get the loud sonic crack. With subsonic & my 15-22, the loudest sound is the bolt cycling and the clang of the round hitting steel. With my bolt action CZ, it sounds like a pellet gun.

Be REAL, REAL careful on who threads your barrel. Done wrong, it impacts accuracy & safety. I use ADCO, as they specialize in doing it. I would never let just anyone do it... even if free.

Which Gemtech can? I would only suggest a can with stainless steel innards for ease of cleaning. I think Gemtech had a SS Alpine with M baffles.

CCI Mini Mags will have a ballistic crack out of a 16" barrel. You should use standard velocity or subsonic ammo for best results.

Another thing you might consider is buying an additional 15-22 that already has a threaded barrel. Then see if he will cut your current barrel and thread it at a length the will keep the CCI Mini Mags subsonic. Just put in the form 1 for the SBR at the same time as the form 4 for the silencer...it's only money...

There are plenty of other reasons to GO the trust route. Just because your sheriff is friendly now doesn't mean it will stay that way. Plus if you want others to use it, the trust is easier in the long run. But it's your decision.

All hv ammo will have a sonic crack out of a 16" barrel. Standard velocity ammo is subsonic most of the time (depending on weather).

Gem tech is not the top tier 22lr supressor. Doesn't mean it's bad though. Don't think it's as easy to clean as the sparrow.

You are stuck with sub-sonic ammo if you want it to be quite. Now to find some that will cycle your gun!! Beings rimfire rounds are dirty, you must clean the suppressor very often. I have several different ones. Top of my list is the AAC Element . It's easy to take apart after 700rds. and has the K baffles. The aluminum baffle type erode after a will and loose the efficiency. I had my first one since the early 90's.

As for the barrel threading, factory threading is hard to beat, someone else may just throw a die on it . Factory is done off the BORE.

I would not limit my choices to what a local gun shop has on hand. Check SilencerShop. Good selection and prices. No nonsense folks who are great to do business with.

Another recommendation for ADCO barrel threading. They do great work and they do it proper. I've had 3 barrels shipped in to them for threading and all have had an 8 day turnaround time from the day I dropped it off at the post office to the day it hit my doorstep.

+1 for all of the above. I do not know which gemtech you are talking about? I have used sparrow SS, spectre II, apex from Innovative Arms, Kodiak TL from Liberty Suppressors, that said I am a distributor for Liberty Suppressors and I like Kodiak best. Before you say it, I have had first round pop from all 4 on different days, weather, temp,ammo, etc. You will get a crack from most ammo, with most cans unless it is subsonic. Innovative arms does a integral can on 15-22 upper which is the quietest of all. It is not that difficult to clean, you only hear the click of the action with Federal bulk 36 gr 1250 FPS?. They cut the barrel to about 10" then permanently add the suppressor to keep it over 16" so no SBR. Suppressors do not require ATF permission to travel to a legal location, while SBR's do. The can will only be on 1 gun but you can shoot standard + HV quietly. Depends on your funds, wants, time. Free threading is not free if it is not centered on the bore and you get baffle strikes!! Silencer shop has the best prices of anyone, fast CORRECT paperwork, excellent to work with. I do not know your dealer and I am not degrading his work, just trying to let you know the good, the bad, the ugly!! Check prices, other forums. Be Safe,

vipermd · Jul 30, 2014

I was looking at Silencer shop prices and a Gemtech Outback IID is 270$ shipped and in stock. Just to help you compare if he is selling you the gemtech for 225$, it is new, and that includes his transfer cost, that would be very reasonable, but if the price is 300$, plus 50$ for transfer I would look long and hard before going that way. Again I do not know which gemtech you are talking about, this is there least expensive one. Be Safe,

As I said before, I don't have one however I note some of the Gemtech models mentioned aren't stainless steel... but are aluminum. From my experience, stick with stainless. These cans can be extremely hard to clean. I tried several methods of cleaning mine but found the dip to be the best way... by far. It is easy. Just mix equal amounts of vinegar & hydrogen peroxide in a glass jar, add the stainless suppressor parts, let bubble for 24 hours and then wipe off the residue. No scrubbing whatsoever & shinny as new. DO NOT put aluminum parts in the dip.

I dip mine after every 500 rounds or so. Having a user serviceable can is very important but to me, having one that can be dipped is just as important.

Just remember that the dip is extremely toxic! DO NOT just dump it down the drain!!!

Actually, the residue from any method of cleaning is toxic. Even if you were to sandblast it off, that dust would be toxic. When using the dip, after cleaning the liquid contains lead acetate. I don't touch the stuff. I use tongs to remove the parts from the jar, then wipe them down while wearing gloves. I pour the liquid in a plastic container designed to hold toxic waste & have it labeled with proper hazard labels. At the point the container gets near full, I will give it to folks licensed to take such material. That should be several years down the road.

My setup. I use 35% hydrogen peroxide that I order from Amazon & dilute 50% with water. You can use the normal stuff but this works a bit better, I think.

I have a buddy building mine for the 15-22 out of titanium. Which I can get a little cheaper than the price of most places online. His 15-22 is quiet enough that he could be shooting it and u could still hear a mouse fart. Plus it'll be a custom one off CAN. I've always been a sucker for customs.

once the sheriff signs off...it doesn't matter if he remains "friendly"or not...his signature merely states there are no local laws forbidding ownership

For that suppressor, yes. But once you have the NFA bug, you will want more items, in all likelihood. A trust is easy to obtain and maintain. I doubt 41p will ever see the light of day IMHO.... Meaning that I don't care which political persuasion my local CLEO has that day.

Ya'll need to look up FIRE CLEAN on You tube, or their web site. I clean after 1500 rounds. NON -TOXIC safe for everybody, and use one drop on Q-tip to coat hole can. To clean it, just air hose it off.

I think it important you understand, the end result of the cleaning is not non-toxic. The lead does not magically go away... nor the other compounds which are in the residue. However, that stuff does sound interesting & I will probably give it a try. Thanks for the heads up.

ChattanoogaPhil · Jul 31, 2014

I looked at the Fire Clean demo. The guy said that the AR bolt would require scraping. That tells me the product doesn't do anything special. If it can't even clean a bolt on an AR without scraping. how is it going to tackle the carbon and lead in a rimfire can?

dullh · Aug 1, 2014

I appreciate the replies. Gemtech is out. Going with the Huntertown Guardian 22 with the stainless baffles. Probably won't actually have it in my grubby paws until next year! All paperwork in done and enroute to Atlanta ATF office...now just gotta wait until my dealer says the paperwork is back.

I do have a habit of getting bit by these "bugs". I know a trust would be the way to go for multiple purchases, but for now I went the individual route.

It sure is a lot of circus hoop jumping for a metal tube...
