Looking For A 5.56 Suppressor For Your AR-15?
When looking for a suppressor for my AR15 I wasn’t sure what I even needed or wanted. What did I expect from a suppressor that would be sending full pressure 5.56/.223 rounds downrange? I had no clue. Hopefully this article will help you if you are in the same boat.
GEMTECH- TREK Suppressor: The Good
One of the most attractive attributes of this particular rifle suppressor is the price. It currently retails from about $475-$500 respectfully on a few different online retailers websites. For me, that’s a strong value considering the performance of this muzzle device. It’s a single contained, zero maintenance, rugged silencer that will perform as expected every time with no fuss. Gemtech claims there is no maintenance or cleaning required so lon as you are only shooting 5.56/.223 normal pressure rounds through it. They didn’t design this particular can to handle low pressure “sub sonic” rounds and they even state that if you want to shoot sub sonic cartridges that you use a specific brand. The majority of commercially available 5.56mm subsonic ammunition does not stabilize in the M16 barrel and will yaw while in the suppressor. Damage caused by this ammunition is not covered under warranty. If it is desired to reduce the bullet flight noise and sonic crack, we suggest that a .22 rimfire adapter be used with standard velocity .22LR ammunition. If subsonic .223 ammunition is a requirement, Gemtech recommends only subsonic ammunition manufactured by Engel Ballistic Research, Inc. To read the full warranty and manual you can Gemtech Trek Owners Manual.
Besides the value the Gemtech Trek suppressor performs consistently well shot after shot after shot. It reduces the overall sound of the gun firing by 29 dB and is the equivalent to shooting .22 shorts out of a .22LR rifle.
Designed specifically to fill the needs of the law enforcement user, the TREK is a compact, durable and lightweight sound suppressor for the 5.56×45 mm centerfire cartridge. The TREK suppressor meets all OSHA and MILSPEC requirements for shooting without the use of hearing protection. The Trek is also available in a lightweight version, the Trek-T, fabricated from high strength, aircraft grade titanium alloys.
So if there were some negatives to point out I would say that it’s the weight. This puppy comes in at 17.1 ounces, and it’s a direct thread onto the end of your barrel. If you have a carbine length system than add another 5.7 inches to the end along with a pound of weight it does fatigue you a little bit in a short time. This is why many may be attracted to the Gemtech Trek-T suppressor which is designed for SBR rifles and is significantly lighter but is also double the price of the standard Trek. Really, aside from the weight, I don’t have much to say that’s negative. The diameter and length is pretty standard with other suppressors designed for the same application.
The only real ugly thing to say isn’t special to the Trek suppressor but applies to all suppressors in my opinion. Your mileage will vary but this particular can will rise in temperature to the tune of 7.5 degrees Fahrenheit, so doing a 30 round mag dump will put your beastly piece of steel at 225 degrees above the ambient temperature. Now, this is the case with most suppressors but because the Trek is a bit long, if you drop it to your chest it’s likely you could burn your inner thigh when transitioning to your pistol during a drill. If you are wearing relatively thick clothing this shouldn’t be a major issue. Gemtech recommends that after 80-100 subsequent rounds fired through the rifle that you let it cool down. This is mostly due to the fact that the copper jacket can become unstable as the lead core can soften at super high temperatures changing the structural integrity of the projectile and therefore putting the suppressor and shooter at risk of a failure or baffle strike. This is a full auto rated suppressor but with any suppressor, heat is the enemy.
Overall, I’m incredibly satisfied with this suppressor, it provides a lot of fun and functionality for a lot of different applications. If you are in the market for an affordable and all around great can with zero maintenance, I’d put the Trek on your short list for consideration. Feel free to ask any questions in the comments and I’ll do my best to respond.
