Daniel Defense SOUNDGUARD SG-30TiL Suppressor, 5/8×24, Black

Product Description

The Daniel Defense SOUNDGUARD SG-30TiL Suppressor (part 06-140-10405) is a titanium rifle suppressor 9.5 in. long and 1.75 in. in diameter, listed by Daniel Defense at 17.2 oz with mount, with a 5/8 x 24 TPI mounting thread and a caliber rating running from .223 through 300 PRC. It is the long-body titanium can in the SOUNDGUARD line.

Length is the honest lever in suppressor design: more internal volume means more room for gas to expand and cool, which makes the SG-30TiL the SOUNDGUARD to look at when sound reduction matters more than a compact profile. Titanium construction is how a 9.5 in. can lands at 17.2 oz with its mount, against the 7 in. stainless SG-30 at 22.5 oz.

The caliber rating is the other reason it gets bought. Rated .223 through 300 PRC, it covers a 5.56 carbine, a 7.62x51mm rifle and a magnum bolt gun with one serialized item. Daniel Defense also states that a patent-pending baffle stack with a proprietary internal coating reduces flash signature to virtually zero, and that patent-pending gas-flow pathing stabilizes rounds and gives negligible point-of-impact shift.

NFA purchase: what buying a suppressor involves

A suppressor is a serialized item regulated under the National Firearms Act and cannot be shipped to your door. The purchase runs as a Form 4 transfer through a dealer holding a Special Occupational Tax stamp, and Western Sport is an SOT. In practice: you buy the can here, it stays in our safe, we submit the Form 4 with your paperwork, fingerprints and photograph, and you take it home once the transfer is approved. We will not quote a wait time or a tax figure on a web page, because both change and only the current answer is useful.

Choosing between the SOUNDGUARD models, and mounting

Daniel Defense lists the SG-30TI at 7.75 in. and 15 oz with mount, sharing this can’s 1.75 in. diameter, .223 – 300 PRC rating and 5/8 x 24 mounting, so the choice is length and weight against internal volume; the stainless SG-30 is 7 in. and 22.5 oz. Mounting is direct thread through the HUB 1.375-24 UNS interface, so the thread meeting your barrel is set by the adapter fitted rather than by the can. We carry those adapters in 1/2 x 28 and 5/8 x 24, including titanium, in muzzle devices; we do not state what hardware is packed with the can, so call to confirm. See also our suppressors.

Frequently Asked Questions

Q: What are the SG-30TiL’s dimensions and weight?

A: Daniel Defense lists the SG-30TiL at 9.5 in. long with a 1.75 in. tube diameter and 17.2 oz with mount. It is the longest of the .30-calibre SOUNDGUARD cans: the SG-30TI is listed at 7.75 in. and 15 oz with mount, the stainless SG-30 at 7 in. and 22.5 oz, all three sharing the 1.75 in. diameter.

Q: What calibers is the SG-30TiL rated for?

A: Daniel Defense lists compatible calibers as .223 through 300 PRC. That range is why the can suits owners wanting one suppressor across a 5.56 carbine, a 7.62x51mm rifle and a magnum bolt gun. Confirm your specific cartridge and barrel length against the rating before shooting it suppressed.

Q: How does the SG-30TiL mount to a rifle?

A: Direct thread. Daniel Defense lists the mounting as 5/8 x 24 TPI and builds the SOUNDGUARD line around the industry-standard HUB 1.375-24 UNS interface, so the thread meeting your barrel is set by the direct-thread adapter fitted to the can.

Q: Do I need a tax stamp to buy this suppressor?

A: Yes. A suppressor is a serialized NFA item and transfers to you on an approved BATFE Form 4 through a dealer with SOT credentials. Western Sport is an SOT, so the transfer happens here. We will not quote wait times or tax amounts because those change – send us a message for the current process.

Q: Will fitting the suppressor shift my zero?

A: Daniel Defense states that the SOUNDGUARD line’s patent-pending gas-flow pathing stabilizes rounds and provides negligible point-of-impact shift. That is design intent rather than a guarantee for your rifle and load, so confirm your zero on paper both suppressed and unsuppressed before relying on it.

Q: Why titanium instead of stainless steel?

A: Weight. The SG-30TiL uses a titanium baffle stack and tube, which is how a 9.5 in. can comes in at 17.2 oz with mount while the shorter 7 in. stainless SG-30 is listed at 22.5 oz. Weight at the muzzle costs more in handling than weight anywhere else, so titanium buys length and internal volume.
