The Daniel Defense NULL 9Ti 9mm suppressor is a weldless, fully 3D-printed titanium can engineered for pistol-caliber carbines and fast-shooting platforms (Daniel Defense part no. 06-140-16309). Its high-flow design minimizes back pressure, which cuts the blowback and toxic gas a PCC pushes toward the shooter. The whole suppressor weighs 4.4 ounces and measures 5.08 inches, so it barely changes how a compact carbine handles. Daniel Defense cites independent testing that puts it at over 75 percent quieter than a bare muzzle under controlled conditions. It ships with a Mini-HUB direct-thread mount for 1/2×28 barrels.

Key Specifications

• Compatibility is 9mm and up to .300 BLK subsonic, covering common PCC and short-barrel subsonic loads.
• It is rated rapid-fire up to .300 BLK subsonic and semi-auto up to .300 BLK supersonic.
• Barrel length rules are no restriction for 9mm or subsonic .300 BLK and a 7-inch minimum for supersonic .300 BLK.
• Overall length is 5.08 inches, which keeps a suppressed PCC short.
• Weight is 4.4 ounces, light enough to leave a carbine’s balance nearly unchanged.
• The mount is a 1.125×28 Mini-HUB direct-thread mount for 1/2×28 barrels, included with the suppressor.
• Construction is weldless, fully 3D-printed titanium, which gives strength and durability at very low weight.
• The finish is clear Type II anodize, a hard surface treatment for the titanium body.

• Independent testing cited by Daniel Defense shows it is over 75 percent quieter than a bare muzzle under controlled conditions.

Frequently Asked Questions

Can the NULL 9Ti be used on a handgun? Daniel Defense says the NULL 9 is not compatible with most handguns out of the box. On a handgun with a tilting barrel it requires a Nielsen device, or piston, for proper function, and it accepts Mini-HUB or SilencerCo Alpha (1.125×28) Nielsen devices.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.

Can I use the NULL 9Ti on a .300 Blackout? Yes, within its ratings. Daniel Defense rates it rapid-fire up to .300 BLK subsonic and semi-auto up to .300 BLK supersonic, with a 7-inch minimum barrel for supersonic .300 BLK.
