Extended-length Daniel Defense Superior Suppression Device in 1/2×28 thread, machined from aerospace 17-4 stainless steel with a salt bath nitride finish. Rated by Daniel Defense for 5.56mm/.223 Rem and 6.8mm/300 BLK barrels.
Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
The Daniel Defense Superior Suppression Device, Extended, 1/2×28 (part 06-048-04165) is a threaded muzzle device for 1/2 x 28 TPI barrels, machined from aerospace 17-4 stainless steel and salt bath nitrided, built in the 2.25 in. extended length and rated by Daniel Defense for 5.56mm / .223 Rem and 6.8mm / 300 BLK. It does two jobs at once: cutting muzzle flash signature and reducing muzzle rise.
Standard 1.875 in. or extended 2.25 in., and fitment
The two lengths are the same device with a different amount of body ahead of the shoulder. The extended 2.25 in. version puts the ports and gas exit plane farther from your support hand and the end of a handguard, which is what you want on a short barrel; the standard 1.875 in. device does the same work in a shorter package. Confirm your barrel’s thread first: this SKU is 1/2 x 28 TPI, and the 5/8 x 24 TPI version will not interchange. See our muzzle devices and the Daniel Defense catalog.

Frequently Asked Questions
Q: What thread does the extended Superior Suppression Device use?
A: This SKU is cut 1/2 x 28 TPI, the thread Daniel Defense uses on its 5.56-class muzzle devices and the common thread on 5.56 and .223 barrels. Daniel Defense also builds the Superior Suppression Device in 5/8 x 24 TPI as a separate item, so check your barrel before ordering.
Q: How long is the extended Superior Suppression Device?
A: 2.25 in. Daniel Defense lists the Superior Suppression Device in two lengths – standard at 1.875 in. and extended at 2.25 in. – and this part number is the extended one. The extra length pushes the ports and gas exit plane forward of the handguard and support hand.
Q: Is the Superior Suppression Device a sound suppressor?
A: No. It is a muzzle device designed for muzzle flash signature reduction and reduced muzzle rise. It is not NFA-regulated and needs no tax stamp or transfer paperwork. A sound suppressor is a serialized NFA item and a different purchase entirely; we handle those as an SOT dealer.
Q: What calibers does Daniel Defense rate this device for?
A: Daniel Defense rates the Superior Suppression Device for 5.56mm / .223 Rem and 6.8mm / 300 BLK. Bore diameter and thread both have to work, so a 300 BLK barrel cut 1/2 x 28 is a normal fit. Outside that list, send us a message.
Q: Will the salt bath nitride finish hold up at the muzzle?
A: That is what it is there for. The body is aerospace 17-4 stainless steel, salt bath nitrided, a combination Daniel Defense chose to keep corrosion and maintenance to a minimum where hot gas, carbon and moisture meet. Check it is still tight after a range session and keep carbon from building up.
Q: Does this device reduce recoil as well as flash?
A: Daniel Defense states the design offers muzzle flash signature reduction and reduced muzzle rise. Reduced muzzle rise is a change in where gas is directed, so the sight settles faster between shots; that is not the same claim as a dedicated recoil brake.
