Fortunately, suppressor use and possession have turn out to be an increasing number of frequent lately. As shooters turn out to be extra conscious of the passive risks concerned with capturing, like lead poisoning and listening to loss, steps are being taken to scale back well being hazards. Suppressors are most likely the simplest instrument we now have towards listening to loss. When you didn’t hear that final sentence, it is likely to be time to choose one up! Nevertheless, silencers (or suppressors, use whichever you need, no person cares) have some drawbacks. The first drawback is that they get highly regarded. This implies mirage throughout precision capturing. It additionally means some highly regarded pants throughout rifle-to-pistol transitions. MODTAC, an organization native to me in Colorado, makes inflexible suppressor shields to mitigate each of those points. They’ve a couple of fashions however at this time we’re trying on the MODTAC U-RAC.

Sizzling Off the Line
Earlier than anything, I wish to be clear about my relationship with MODTAC. Dave, one of many house owners, is a private good friend. I’ve additionally carried out some contract work for the corporate. Neither of these issues implies that the U-RAC might be any roughly efficient throughout testing.
The U-RAC, or Common Rail Connect Coupler is made of some components. The defend itself is constituted of spun carbon fiber and options air vents on the underside. The tube is connected to the coupler utilizing spring-loaded threads and a 90-degree flip and is free-floated. Line up the index factors and twist. The coupler design is such that it can’t be over-torqued.
The coupler is CNC machined in-house from 6061-T6 aluminum. The “Common” a part of the equation is available in with the rail-grabber. MODTAC’s different mannequin, the M-RAC, is made to suit particular rails. The U-RAC is made to suit EVERY rail. Effectively, nearly. All AR-15s with a prime Picatinny rail are suitable, in addition to AR-10, HK-416, and SIG MCX/MPX platforms.
Heating Issues Up
We’re going to do two issues for this evaluation. I wish to do some sensible testing, in addition to technical testing. Let’s begin with the previous.
I’ve the U-RAC on an Aero decrease with a Daniel Protection RIS III higher. I’ve a SureFire SOCOM556 MINI2 suppressor connected and I’m capturing Stand 1 55-grain 5.56. After a couple of high-round depend drills to warmth the gun up, I let the defend relaxation on my pants.
The U-RAC will get scorching and is likely to be uncomfortable towards your leg. As a lot as we strive, it’s inconceivable to defy physics. That stated, my pants left the vary intact. That’s because of the airflow across the can. The hole between the U-RAC and suppressor permits air to chill the can and movement out the entrance, whereas the vents on the underside attract recent, cool air. The consequence on pants is much totally different with a naked suppressor. Now, let’s do some temperature testing. We loaded up 90 rounds and dumped them into trash over the course of 9 minutes. Utilizing a temperature reader, that is what we discovered.
Thirty rounds in three minutes
Suppressor temp: 470 F
U-RAC temp: 156 F
Ninety rounds in 9 minutes
Suppressor temp: 651 F
U-RAC temp: 323 F
The Burning Conclusion
The U-RAC is a useful accent should you plan on capturing sufficient to warmth up your can. Some will complain about the associated fee and examine the MODTAC U-RAC to material wraps. The associated fee is excessive as a result of the standard is excessive. We noticed a mean temperature drop of 55-60% in comparison with a naked suppressor. Plus, if you would like components which might be made in America, the associated fee goes to be greater. Whereas material wraps are additionally efficient at protecting temperatures down, they keep that warmth, making the return to ambient temperature a sluggish course of. If it is a working gun, chances are you’ll not have that form of time.
I recognize the usage of carbon fiber for its power, however much more so for its weight. Placing a suppressor on the finish of an already lengthy barrel makes a rifle front-heavy, so I’d fairly not add extra weight. The free-float design just isn’t solely aesthetically pleasing however maintains the advantages of a free-float rail.
I nonetheless don’t advocate touching the defend together with your naked arms after a rigorous course of fireside. That’s not the meant use of the U-RAC and it’s going to harm. I’ll say that it’s nonetheless a lot better than contact with a forbidden popsicle and can most likely save your gear.
When you’re the kind to go put one field by means of the middle of a bullseye on the vary, perhaps this isn’t for you. When you take all-day lessons or magazine dump into the dust, I believe it is a helpful accent to guard you from your self. Errors occur. You may by no means plan to the touch your suppressor, however should you do, you’ll be pleased you invested in a Suppressor Protect.
When you’d prefer to get extra data, head to the MODTAC website. Be sure you additionally observe alongside on MODTAC’s socials. They are often discovered on Instagram and YouTube or reached by means of their customer support e-mail if in case you have fitment questions. Defend your pants!
