Welcome back to another edition of TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturer’s of the YHM Nitro N20 modular titanium suppressor. Last weekend was the final exam for my horse grooming certification, so Adam was nice enough to step in and take the reigns. If you missed it, he reviewed the Stealth Project Recon rifle suppressor. Wrapping up TFB/TFBTV Gunfest 2021 in New Orleans, we get a brief look at the Spike’s Tactical Compressor integrally suppressed AR-15.

Thank you to:

• Our new friends and fellow suppressor lovers at Tracey’s Bar on Magazine Street in NOLA.
• Primary Arms for letting us borrow the Compressor with their new ACSS SLx optic ($169).
• Ryan Ogborn (@gunhipster) for the fantastic photography.

Please keep in mind that this was an impromptu review consisting of 30 rounds on an indoor range. First, let’s take a look at the details and the specifications.

Spike’s Tactical Compressor

Upper – $2,529

Complete Rifle – $2,742

The Compressor upper was designed for the enthusiast who demands attention to detail at every turn. This rifle was made famous by Travis Haley in his legendary long-range videos. It is devilishly accurate, ultra sexy, and reliable. Our prototype model has nearly 15,000 rounds through it and still bangs steel. Many companies have attempted to make copycats of the Compressor and none of them come close.

Function:

The Compressor is built around the Spike’s Tactical LRS modified reflex silencer. My first assumption that the Compressor had the silencer pinned and welded to the mount to avoid having to buy two stamps – one for the can and one for a short barreled rifle. However, seeing that it uses the LRS reflex style mount, I couldn’t see an effective way to permanently attach it to the barrel or gas block.

As you probably already know, a reflex suppressor adds extra internal volume without adding extra overall length. The trade off is that the mount uses a collar with a shoulder that slips over a barrel with a specific diameter. In this case the collar seems to rest right up on top of the gas block.

The short barrel is radially fluted for cooling but it does also add a unique look. While I’m not opposed to an 8.1” Barrel for 5.56, it does effect two important characteristics: terminal ballistics and noise reduction. A barrel length of 10.3” for a 5.56mm rifle is about as short as I like to go; all that unburned powder in anything shorter just becomes extra noise. In 300BLK an 8” Barrel with a 1:5 twist would make for a solid shooter for both subsonic and supersonic rounds.

One unique feature is the coiled copper heat sinks that wrap around the gas tube.

Shooting The Compressor:

From behind the gun, the compressor sounded as good as anyone could expect for a short barrel supersonic round. Add in the fact that we were on an indoor range and I was impressed.

This setup did seem to be fairly gassy, making my eyes water after just one magazine. Again, I think a 300BLK compressor would make a better choice and would cutdown on the gas, especially when using subsonics. I also wonder if some forward venting on the LRS would help with reducing the amount of gas traveling back down the barrel.

Thanks for reading. Be safe, have fun and we’ll see you here next weekend for another Silencer Saturday.
