Welcome to the only independent online resource for civilian legal silencers. This website is dedicated to researching the ins and outs of silencers in practical civilian use. I will be conducting tests on various weapons and silencers and sharing those results here. Just signup with the link above so you can access the forums and stay up to date with all the latest silencer developments and chat with industry professionals. Using the information provided may save you the expense and headache wasting $500-$1,000 on a loud silencer or one that doesn't properly fit your needs. Is there such a thing as a loud silencer? You bet there is! Don't waste your hard earned dollars on one.
Some of the free tests include the AAC Prodigy, the Gemtech Outback II, the LRM M169 9mm upper, the Tac 67 cleaning pictures, the SRT Arms Integral 9MM system, the John Norrell Ruger 10/22 and others. Many videos are included and lots of pictures are located in the reviews so you can see what everything looks and sounds like. Heads up shootouts with the Beretta 92FS, the Glock 17, the Sig P226 Tactical and the H&K USP 9SD are available with many different 9mm silencers.
Some product reviews are available on the website such as a review of the Aguila 60 grain SSS rounds, the Blackdog Machine 22LR magazines, and the JG Bolt lock for the 10/22. Other reviews will become available soon. The full bodied Black Dog Machine Mag will be reviewed soon!
Other silencer reviews are coming up in the future and will provide you with in depth detail of each silencer.

I don't take money from manufacturers, dealers, or advertisers, so your support is vital in keeping the reviews coming.
Free Silencer Review and Tests
SRT ARMS
INTEGRAL 9MM UPPER
This is a review of the SRT Arms 9mm upper for the AR15/M16 weapons platform. Four types of ammunition were tested for sound signature and velocity was recorded for each shot. (requires FREE signup, if you are not already a member)
Hearing Protection LLC Checkmate 22LR
Silencer
On November 23, 2007 I reviewed the Hearing Protection LLC Checkmate 22LR silencer. The Checkmate is a monolithic baffle silencer that uses a three lug attachment system. It can be used either with or without a rubber wipe. The silencer is all aluminum and can be disassembled by the end user for maintenance. For this review I also shot two other monolithic baffle silencers for comparison. I tested the YHM Mite and the AAC Prodigy with two types of ammunition on the P22.

357 Magnum
Suppressed Rifle
On November 18, 2007 I tested a New England Firearms Handi Rifle chambered in 357 Magnum with four 9MM silencers. The weapons barrel has been shortened to 16.1 inches and threaded to accept the silencers using the 1/2X28 TPI threading. In this review we tested some hand loaded 180 grain jacketed hollow points.

AAC M41000
vs. YHM Stainless Phantom 5.56 Silencer
Shootout
On December 23, 2007 I shot the first official 5.56mm silencer shootout. The silencers I tested in this review are the Advanced Armament Corp. M41000 and the Yankee Hill Machine Company Stainless Phantom. They were tested on the M4 Carbine with both 14.5" and 10.5" barreled uppers. The ammunition tested was M193 55grain military ball with Lake City head stamp. Also tested were some 5.56mm TTI Armory Subsonic rounds. (requires FREE signup, if you are not already a member)
Liberty
Suppressors Shoofly
On April 20 ,2008 testing resumed here at Silencer Research and I reviewed a new suppressor from Liberty Suppressors called the Shoofly. The Shoofly is a smaller than usual diameter 22LR silencers and was designed to match the outside profile of a bull barreled Ruger 10/22. (requires FREE signup, if you are not already a member)
YHM Stainless Steel Mite
On May 26th 2008 I reviewed the Yankee Hills Manufacturing Stainless Steel Mite. This particular version comes with the Quick Detach system to speed up mounting and dismounting the suppressor from the host weapon. The silencer is full-automatic rated, disassembles for cleaning by the end user (requires FREE signup, if you are not already a member)
Reflection Tests
I performed a test to determine what difference, if any, the testing location has to do with sound pressure level readings. I tested 4 weapons with 4 silencers in 4 different locations on the same day. I tested the John Norrell integral 10/22, the AAC Prodigy on the Browning Buckmark, the AAC Evolution 9 on the Sig P226T and the Gemtech M496D on the M16 with 14.5 inch barrel. One of the main reasons for performing the test was to see if tests in an open field over grass would be similar or comparable with tests done on my official test range.

TAC 67 Disassembly pictures and commentary
This now discontinued model silencer has one stainless steel blast baffle followed by 4 aluminum baffles. Both end caps are threaded to allow complete disassembly by the end user. The baffles used in this silencer are the ported "K" baffles. The pictures here are indicative of around 1,700 rounds fired from a fully automatic M16 22LR conversion. This review is only of the silencer internals.
John Norrell Arms, Inc. Custom Silencer
This large 22 can was built by John Norrell Arms, Inc. as a custom project. The criteria were excellent suppression coupled with a longer cleaning interval and extra weight to help control muzzle flip. The cleaning pictures that are located in the subsequent page show around 5,000 rounds of fully automatic fire from an M16 22LR conversion. These baffles are "M" baffles. This silencer might be one of the largest 22LR silencers in existence.
LRM
169 vs Gemtech Talon w/Trinity
This review of two 9mm uppers for the M16 platform include pictures, ballistics, and some videos. Videos of silencers are deceiving as they don't adequately represent the way a silencer sounds in real life. One of the goals of Silencer Research in the future is to make realistic videos that more closely replicate the sound of real suppressed gunfire. The LRM 169 is an integral upper for the M16. The Gemtech Talon upper is a non-integral upper for the M16. The Gemtech Talon upper is designed to be fitted with a Gemtech Trinity 9mm can. The Gemtech Talon requires the use of 147 grain ammunition in order for the velocity of the projectile to remain subsonic. The LRM 169 does not require the utilization of 147 grain "subsonic" ammo. One can shoot almost any type of regular 115 or 124 grain 9mm ammo and the M169 bleeds off the gases to make the round subsonic. This isn't an official sound test, and was done long before I started this site.
The John Norrell Arms Ruger 10/22
integral silencer
I tested 5 types of high velocity ammunition for both dB and ballistics/velocity. I have fired at least 12,000 rounds of CCI Minimags through this suppressor. The ammunition produces very consistent velocities and seldom causes any cycling problems. I loaded an Eagle 30 round plastic magazine with 15 rounds and fired the weapon to test for dB levels as well as the velocities.
Buckmark
vs. Ruger
I performed a short test to see what Tactical Solutions barrel was quieter, as well as compare other features and options when using the Tactical Solutions barrels. The Browning Buckmark uses the Trail Lite barrel and the Ruger series uses the Pac Lite receivers. Both are high quality products with pros and cons. The Tactical Solutions aftermarket products greatly reduce the weight of the factory guns. I believe they also increase the accuracy.
9MM SHOOTOUT and PISTOL TRIALS
On July 22, 2007 I did an extensive review of three 9mm silencers with 4 separate popular pistols. I used 3 common ammunition types. The test was to determine the sound pressure levels of each pistol and each silencer as well as to determine the optimum combination. I also tested the ballistics of each ammunition type both with and without the silencers attached.
LRM M169 TEST RESULTS
On March 17, 2007, I tested the LRM upper on a factory Colt M16A2 registered lower receiver. I tested 6 types of factory loaded ammunition for ballistics/velocities and for dB measurements. The LRM 169 was loaded with 10 rounds of each type of ammo. No jams or weapon malfunctions were noted during the entire test. There is no way to test the LRM unsuppressed as it is an integral upper and you cannot remove the silencer for an unsuppressed reading.
