Order the standard black MK18 SBR with magazine instead if you do not need it. Magazine rules are a local matter and they move, so satisfy yourself about the current requirements for your jurisdiction.

Frequently Asked Questions

Q: What exactly does the no-magazine MK18 SBR leave out?

A: The magazine and nothing else. Barrel, RIS II rail, bolt carrier group and furniture are the standard MK18 short-barrelled rifle specification. Daniel Defense issues the separate part number so buyers in capacity-regulated jurisdictions can take the firearm and add a locally sourced magazine.

Q: Why is the RIS II rail significant on this build?

A: The MK18 RIS II is the Picatinny quad rail Daniel Defense supplies to USSOCOM, using a patented 6-bolt Bolt-Up System tested before fielding. It free floats the barrel and gives continuous rail surface on all four sides for lights, lasers and night vision.

Q: What magazines does this MK18 short-barrelled rifle take?

A: It is an AR-15/M16 pattern firearm, so magazines for that pattern apply, with capacity being the locally governed variable. Verify the rules currently in force for your jurisdiction, then call 817-393-4000 and we will work out a compliant magazine to pair with it.

Q: Does the tax stamp requirement change without a magazine?

A: No. The 10.3-inch barrel is what puts this firearm under the National Firearms Act, so a BATFE tax stamp and an approved transfer through a Special Occupational Tax stamp holder are required. Western Sport is an SOT. We publish no wait times or tax amounts.

Q: How heavy is the MK18 SBR and how long is it?

A: This configuration weighs 5.88 lbs, with an overall length between 26 3/4 and 29 7/8 inches with the muzzle device depending on stock position. Optics, a light and a loaded magazine will add meaningfully to that bare weight in practice.

Q: Why the 10.3-inch barrel length specifically?

A: The 10.3-inch Cold Hammer Forged barrel is the same length used on the MK18 upper most commonly chosen for close-quarters work, which is the whole point of the platform. It runs a carbine-length gas system behind a Daniel Defense Flash Suppressor on 1/2 x 28 TPI threads.
