Key Highlights
When we first unboxed these in late 2025, our team noticed the improved machining tolerances compared to previous generations. The threads engage smoother, and there’s zero play when mounted—something our customers frequently mention in reviews.
The Good and the Bad
✅ What works:
- Exceptional value at this price point (we’ve had zero warranty claims)
- Lighter than most competitors—our scale showed 5.9 oz vs advertised 6.1 oz
- No first-round pop that plagues some budget suppressors
- Maintains zero well on precision rifles (tested on 6.5 Creedmoor bolt guns)
- Minimal gas blowback compared to similar designs
❌ What could improve:
- Not the quietest in its class (though it’s within 2dB of suppressors costing $100 more)
- Direct-thread only—no quick-detach option
Who It’s For
Buy if: You want reliable suppression without breaking the bank, especially for plinking or hunting applications where absolute silence isn’t critical.
Skip if: You need ultra-lightweight titanium construction or plan to run full-auto frequently.
What Buyers Ask
Where can I buy this online?
Right here at Californiagunshop—we’ve shipped 112+ units with same-day dispatch.
Does it come with a muzzle device?
No, this is direct-thread only. We recommend pairing it with our AR-15 muzzle devices if you need a brake or flash hider.
How’s the durability?
In our testing, it handles 500+ rounds of .308 without significant carbon lock. Two customers reported 2,000+ rounds on their 5.56 hosts with no issues.
Can I use it on multiple calibers?
Yes—it’s rated for .30 cal and smaller (e.g., .223, 6.5mm). We don’t recommend .338 Lapua or larger.
What’s the lead time for Form 4?
Current ATF processing is 8-10 months. We submit paperwork within 24 hours of purchase.
Does it work with left-hand threads?
This model is right-hand only. Contact us for left-hand options.
How’s the tone?
Customers describe it as a mid-to-low frequency thump—less sharp than some aluminum suppressors we’ve tested.
