SILENCER SATURDAY #309: Bolt Motion Rifles and the SureFire SOCOM556-RC3

Good afternoon everybody and welcome again to TFB’s Silencer Saturday delivered to you by Yankee Hill Machine, producers of the brand new YHM R45 Multi-Host Suppressor. Final weekend we have been on the vary with the latest SureFire rifle suppressor. We wrap up the sequence immediately with the SureFire SOCOM556-RC3, towards the SureFire RC2, and the SureFire MINI2 on a bolt motion rifle in an try and discern any variations. How does the brand new, low-back strain silencer sound on a closed motion host? Let’s discover out.

SILENCER SATURDAY #309: Bolt Motion Rifles and the SureFire SOCOM556-RC3

In the present day’s episode can be transient since we’re on the eve-eve of the Christmas Vacation. From everybody right here at TFB we want all of our readers a secure and blissful vacation season.

The SureFire SOCOM556-RC3 is particularly designed for battle/defensive carbine use, sturdy sufficient to deal with heavy charges of fireplace, geared up with one of many business’s finest mounting programs, and designed with optimizing fuel movement and lowering again strain as a major mission. It’s secure to say that the product designers and engineers didn’t optimize this suppressor for bolt motion rifle hosts.

As we’ve mentioned, tight bore diameters, baffle designs, and total size are the first issues for sound discount efficiency – if fuel movement just isn’t a priority. The much less sound that may escape the bore, the quieter the report. Sadly, in relation to supersonic rounds just like the 5.56×45 cartridge, even the most effective suppressors can be overpowered by the sound of the bullet breaking the sound barrier. That occurs at about 1,070 ft per second and above, and 5.56 rounds sometimes have muzzle velocities above 2,000 fps.

If you’re in search of a listening to secure rifle-caliber platform, your finest wager is a bolt motion rifle in 300BLK and a high quality suppressor. SureFire makes the SOCOM303-SPS which is a high performer for subsonic 300BLK.

On a bolt motion rifle, the fuel and strain from the cartridge solely has one exit level – the muzzle. Including further vents to a suppressor permits the fuel further exhaust factors, with out having the difficulty of a strain differential between the suppressor and a fuel system or a chamber being unlocked. The query is, do these additional vents cut back the general noise suppression efficiency.

As soon as once more, let’s check out the numbers.

Utilizing a suppressor on a 5.56 bolt motion rifle with an extended barrel is surprisingly nice. It is a superb reminder of why again strain mitigation is so essential on fuel weapons; the extra sound and fuel that will get pushed ahead and away from the shooter the higher. Preserve all of that power out of the motion.

All three of those suppressors, the RC3, the RC2, and the MINI2 carried out nicely, bringing the noise all the way down to the extent of an unsuppressed rimfire rifle. The MINI2 was the loudest of the three by no less than three decibels (my ear estimation. The RC2 was the “quietest” of the group.

Whereas the RC3 was louder than the RC2, it was solely by about two decibels or much less (once more, my private estimation). I needed to swap backwards and forwards between the 2 suppressors to essentially inform the distinction. My guess is that most individuals wouldn’t discover.

The SureFire SOCOM556-RC3 was constructed for carbines, so my expectations for the bolt motion efficiency have been on the low aspect. However even with all of that ahead venting, it sounded nearly as good as could possibly be anticipated.

Thanks for studying. Be secure, have enjoyable, and we’ll see you again right here subsequent weekend for one more Silencer Saturday.
