Clash of the Titans 3: Vepr AK47 vs Daniel Defense AR15; Concrete & Water

Published on November 6, 2016
Duration: 6:40

This video compares the durability of a Daniel Defense DDM4 V11 LW and a Vepr AK47 through concrete drops and water submersion. Both rifles demonstrated good operational reliability after the tests, though the Daniel Defense rifle experienced a rail shift of approximately 2mm to the right due to a loose barrel nut mechanism, potentially affecting zero if iron sights were used. The Vepr AK47 showed minor cosmetic damage to the dust cover and front sight post but maintained its zero. Both rifles performed well in water, with the AK's piston system and the AR's direct impingement system handling submersion after proper draining.

Quick Summary

In a head-to-head durability test, the Vepr AK47 and Daniel Defense DDM4 V11 LW were subjected to concrete drops and water submersion. While both rifles remained functional, the DDM4 experienced a rail shift, potentially affecting zero, whereas the AK sustained only minor cosmetic damage. Both handled water submersion well after proper draining procedures.

Frequently Asked Questions

How did the Daniel Defense DDM4 V11 LW perform in concrete drop tests?

The Daniel Defense DDM4 V11 LW was dropped onto concrete multiple times. While it functioned without issues, a closer inspection revealed the rail had shifted approximately 2mm to the right, suggesting a potential loosening of the barrel nut mechanism. This shift could impact zero if iron sights were used.

What were the results of the Vepr AK47's concrete drop test?

The Vepr AK47 also underwent concrete drop tests. It sustained minor cosmetic damage, primarily to the dust cover and front sight post, but maintained its operational integrity and did not experience any mechanical shifts that would affect zero.

Is it safe to submerge an AR-15 in water?

Yes, but with precautions. For AR-15s with direct impingement gas systems, it's crucial to drain the gas system after submersion to prevent potential over-pressure issues from water expansion. Piston-driven systems like on the Vepr AK47 are generally less sensitive but draining is still advised.

Did the Vepr AK47 or Daniel Defense DDM4 perform better in water tests?

Both rifles performed very well in water submersion tests, cycling rounds without malfunctions after draining. The Vepr AK47 ejected a noticeably larger amount of water upon firing, indicating it retained more water internally than the Daniel Defense rifle.
