Meet the PENTA 556 by Shadow Silencers
This episode features the PENTA 556, a modular direct-thread suppressor designed for 5.56/.223 rifles. Built with versatility in mind, the PENTA includes adjustable baffles, allowing shooters to fine-tune the length and sound suppression level depending on their setup.
- Threading: ½ x 28 (standard for 5.56 platforms)
- Caliber: 5.56/.223 only
- Construction: Modular, adjustable baffle system
- Heat Dissipation: Enhanced with external ridges to cool faster after sustained fire
Setup and Maintenance Tips
Brandon and Roger walk viewers through the proper setup before shooting. Key steps include:
- Pre-lubing the threads using the anti-seize lubricant included in the box
- Following a break-in process: fire two shots, retighten, repeat
- Ensuring baffles stay accessible after carbon buildup through routine cleaning
Suppressors can get carbon-locked fast. A little prep saves a lot of hassle later on.
Performance on the Range
The PENTA 556 performs well on the range. Here are the highlights from the session:
- Noticeable noise reduction, even with the supersonic crack of 5.56 rounds
- Minimal blowback to the face compared to other suppressors
- Solid construction with very little loosening after heat buildup
- Point of impact shift observed, as expected with most suppressors
If you plan to keep the suppressor mounted, a quick re-zero of your optic is recommended.
Why Now is the Right Time to Buy a Suppressor
The video also touches on upcoming changes to suppressor regulations. According to Brandon and Roger, starting January 1st the $200 tax stamp may be removed. However, prices are expected to increase significantly due to higher demand.
Currently at Sheepdog Gun Armory, they handle the entire process in-house. That includes fingerprinting and photo capture, with many customers seeing approvals in just two days.
