Daniel Defense DD5 Critical Components Parts Kit

Product Description

The Daniel Defense DD5 Critical Components Parts Kit (part 28-088-15219) is a package of twelve frequently requested replacement parts for a DD5 V3, V4 or V5 chambered in 7.62x51MM, 6.5 Creedmoor or .260 Remington: Gen II firing pin and extractor, gas ring, DLC-coated ejector, springs, roll pins and the 7.62 buffer action spring.

Read the platform line carefully. This is the DD5 kit, for Daniel Defense’s large-frame 7.62/6.5 rifles. It is not for a DDM4, an AR-15 or an M16: the firing pin, extractor and extractor spring are 7.62 GEN II parts and the action spring is the 7.62 buffer spring. A separate DDM4 Critical Components Kit covers 5.56MM, 6.8 SPC and 300 Blackout.

Is this kit right for your rifle?

Check the model – V3, V4 or V5 – the chambering, and the generation, because these are GEN II parts. The three chamberings share the same large-frame bolt and carrier architecture, which is why one kit covers all of them. If your DD5 is earlier, or you are unsure, call 817-393-4000 before ordering. See our parts catalog and upper receiver parts.

Frequently Asked Questions

Q: Does the DD5 Critical Components Kit fit an AR-15 or a DDM4?

A: No. This kit is for the DD5 V3, V4 and V5 in 7.62x51MM, 6.5 Creedmoor or .260 Remington. The parts are 7.62 GEN II components and a 7.62 buffer action spring, not interchangeable with 5.56 parts. A separate DDM4 Critical Components Kit covers 5.56MM, 6.8 SPC and 300 Blackout.

Q: What exactly is in the kit?

A: Twelve parts: a 7.62 GEN II firing pin, extractor and extractor spring, a 7.62 gas ring, a DLC-coated ejector, an ejector and safety detent spring, two split roll pins, a GEN II buffer extractor, a carrier buffer retaining ring, a DD5 GEN II firing pin return wave spring and a 7.62 buffer action spring.

Q: Will it work on a 6.5 Creedmoor DD5 as well as a 7.62?

A: Yes. Daniel Defense lists the kit for a DD5 V3, V4 or V5 chambered in 7.62x51MM, 6.5 Creedmoor or .260 Remington. Those chamberings share the same large-frame bolt and carrier architecture on the DD5, which is why a single parts kit covers all three.

Q: Do I need a gunsmith to fit these parts?

A: Most are owner-serviceable with basic tools and some care, since extractors, gas rings and detent springs are routine bench work. The retaining ring and the firing pin return wave spring are fiddlier. Call 817-393-4000 if you would rather our gunsmith fitted them.

Q: Is this a service kit or an upgrade kit?

A: A service kit. Daniel Defense describes it as frequently requested parts for your DD5 in one convenient package – the items that wear, break or get lost. It does not change how the rifle performs; if you want to change the rifle rather than maintain it, call us.

Q: Which DD5 generation are these parts for?

A: The kit is specified around GEN II components: the firing pin, extractor, extractor spring, buffer extractor and firing pin return wave spring are all listed as GEN II parts. If your DD5 is an earlier generation or you are unsure, call 817-393-4000 with the rifle’s details before ordering.
