Frequently Asked Questions

How accurate was the Daniel Defense M4V11LW after 5000 rounds?

After 5000 rounds without cleaning, the Daniel Defense M4V11LW achieved impressive accuracy. It produced a 1.296 MOA group at 100 yards and an even better 0.931 MOA group at 500 yards, demonstrating its potential for precision shooting.

What were the main durability concerns with the M4V11LW after the endurance test?

The primary concern was a significant rail shift after drop tests on frozen ground, even with Loctite. This compromises the ability to maintain zero for mounted accessories like lasers, which is critical for tactical applications.

Does the lightweight barrel on the M4V11LW hold up well?

Yes, the Daniel Defense lightweight barrel performed well, maintaining accuracy even when heated during sustained fire. This challenges the notion that only heavier barrels are suitable for such conditions.

What was the condition of the internal components after 5000 rounds?

Internal components like the bolt carrier group, firing pin, and cam pin showed expected carbon buildup but no significant structural damage or excessive wear. The gas keys were properly staked, and locking lugs were intact.
