Frequently Asked Questions

How does the KGM R30T suppressor perform in terms of accuracy compared to the Thunderbeast Arms Ultra 9?

In extensive testing, the KGM R30T achieved a 20-round group of 1.03 MOA, while the Thunderbeast Arms Ultra 9 achieved 1.34 MOA (without a flyer). This suggests the R30T offers comparable or potentially superior accuracy for long-range precision shooting.

What are the key features of the KGM R30T suppressor?

The KGM R30T features a titanium construction, a taper mount system for secure attachment, and an adjustable port end cap that allows users to tune recoil mitigation and muzzle flip. It is magnum rated up to 300 Norma.

Does the KGM R30T offer better recoil mitigation than the Thunderbeast Arms Ultra 9?

Yes, testing indicated that the KGM R30T, even with its ports closed, provided less felt recoil than the Ultra 9. With the ports open, the R30T significantly reduced recoil impulse and muzzle flip, allowing for faster follow-on shots and better target tracking.

What is the sound suppression quality of the KGM R30T compared to other suppressors?

Subjective testing found the KGM R30T to have a deeper, more pleasant tone than the Thunderbeast Arms suppressors, which were described as having more of a 'crack'. While both are top-tier, the R30T's tone was preferred by some testers for its less sharp sound signature.

What is the significance of KGM winning a DOJ contract for the FBI?

KGM's recent win of a $3.9 million DOJ contract for the FBI's sniper rifle systems signifies substantial government validation of their suppressor technology. This contract involved extensive testing against other suppressors, highlighting KGM's performance capabilities.
