Daniel Defense DD5 Gen II Bolt Assembly

Product Description

The Daniel Defense DD5 Gen II Bolt Assembly (part 04-013-30156) is a replacement bolt assembly for Daniel Defense’s DD5 platform – the large-frame rifles in 7.62x51mm and 6.5 Creedmoor – in the Gen II configuration. It will not fit a DDM4, an AR-15 or an M16.

That distinction is the most important thing on this page. Large-frame and small-frame AR-pattern rifles use entirely different bolts, and Daniel Defense’s catalog carries both: a 5.56 NATO / 300 Blackout bolt assembly for the DDM4 family, and this Gen II assembly for the DD5.

What we will not state, and what to check

We are not stating the bolt’s steel, coating, weight or the precise list of DD5 models it is approved for, because we do not have that confirmed for this part number and a wrong bolt specification is not a harmless error. Call 817-393-4000 with your DD5’s model, chambering and serial number and we will confirm fitment first. Note too that this is a bolt assembly, not a complete bolt carrier group. See bolts, slides and frames and bolt carrier groups.

Frequently Asked Questions

Q: Will the DD5 Gen II bolt assembly fit a DDM4 or an AR-15?

A: No. This is a DD5 part, for Daniel Defense’s large-frame 7.62/6.5 platform. Small-frame AR-15 and DDM4 rifles use a completely different bolt, and Daniel Defense sells a separate 5.56 NATO / 300 Blackout bolt assembly for those. Do not order this part for a 5.56 rifle.

Q: Which DD5 models and chamberings does it fit?

A: It is the Gen II bolt assembly for the DD5 platform, which Daniel Defense builds in 7.62x51mm and 6.5 Creedmoor. We are not publishing a model-by-model fitment list, because we do not have one confirmed for this part number. Call 817-393-4000 with your model and chambering and we will confirm it.

Q: What is a bolt assembly, as opposed to a bolt carrier group?

A: A bolt assembly is the bolt and its small parts – the part that locks into the barrel extension and holds the extractor, ejector and gas rings. A bolt carrier group is that plus the carrier, gas key and cam pin.

Q: What does Gen II mean on a DD5 part?

A: It identifies the generation of DD5 components it belongs to. Daniel Defense uses the GEN II designation across DD5 parts: its DD5 Critical Components Kit is built around 7.62 GEN II firing pins, extractors and extractor springs. Match the generation to your rifle.

Q: Should I keep a spare bolt for my DD5?

A: If you shoot it seriously, yes. The bolt carries the locking lugs, extractor, ejector and gas rings – the highest-stress parts in the rifle – and it is the one component whose failure stops the gun with no field workaround. A spare turns a broken extractor at a match into a two-minute swap.

Q: Do you know what steel and coating this bolt uses?

A: Not for this specific part number, so we are not printing one. What we can say is that the DD5 platform’s bolt is designed with enhanced extractor geometry and dual ejectors for reliable cycling. If material or coating will decide your purchase, call 817-393-4000 and we will get it confirmed.
