    Don’t understand stand why they don’t offer a non pinned version, not everyone want to run that flash hider.

  2. Ruban Mora on May 4, 2023 at 4:05 am

    With the surefire comp what’s the exact measurement for the barrel and pinned device?

  3. St3V3 STich on May 4, 2023 at 4:06 am

    Once you pin and weld the flash hider is the barrel considered 16" OAL and not require NFA nonsense?

  4. Gato Grande on May 4, 2023 at 4:08 am

    Any can for it?

  5. Frank Christopher on May 4, 2023 at 4:09 am

    What handguard did you say that was ? Wrist 2?

    In general – Do you like quad rails over slim handguards ?

  6. FOG on May 4, 2023 at 4:10 am

    Did you get DD to pin weld that Surefire flash hider for you?

  7. Nathan on May 4, 2023 at 4:10 am

    Does this have the heavy socom barrel or the m4 profile barrel?

  8. Sug on May 4, 2023 at 4:11 am

    Do you put the gas block on after the handguard? I have always wondered how that handguard goes around the front sight block.

    Pretty similar to the build I’m working on. Small differences.
    1. Brownell’s special DD M$A1 SOCOM stripped 14.5 upper with FCD 6315 Keymo FH.
    1a. Aero Precision Nickel-Boron BCG
    2. ZRO-Delta stripped lower w/ Redi-Catch Mag-release (pending)
    3. Geissele SSA
    4. CMMG lower parts kit (pending)
    5. SOLGW A5 buffer kit
    6. Aero Precision Breach Ambi-charging handle
    7. B5 P23 grip in Coyote Brwn (w/ 2032+CR123 plug)
    8. Magpul STR
    9. Magpul RVG
    10. Troy HK-style BUS.

    Eventually a Dead Air Sierra5 with E-brake. Waiting for some of the quality issues to get worked out.

    What’s the rail length?

  12. King Kong46 on May 4, 2023 at 4:16 am

    I was thinking about adding a eotech to my ddm4v7

  13. Kevin Reeves on May 4, 2023 at 4:17 am

    Does your eotech still cowitness?

  14. Gato Grande on May 4, 2023 at 4:18 am

    I dig it

  15. Tyler Tapp on May 4, 2023 at 4:19 am

    Pretty dope. You say that riser was called a bobro? Is that the same hieght as the unity? Oh and something I found that works with the maritime bolt catch, only if it interested you… is a knights ambi mag release actually works with it without having to be modified. Just recently got one to test and it works great.

  17. Ethan Hernandez on May 4, 2023 at 4:31 am

    How you like that griffin rear sight? Looks like a nice cheaper alternative to the knights

  18. revolutionanarchy713 on May 4, 2023 at 4:33 am

    Deets on the sweet watch please! Thank you!

  19. Fuzzy Peach on May 4, 2023 at 4:41 am

    Been considering the HRF magwell. Is it worth the money? Seems like it might help with mag changes, but the AR already has a flared magwell.

  20. m07c on May 4, 2023 at 4:46 am

    Hey Nice Rifle….where are those mags from?They look really nice!

  21. ReticentIndignation on May 4, 2023 at 4:50 am

    Love it! Would love to pick up a DD upper like this, alas I’d rather at this point get a 13.9.

  22. RebelViking912 on May 4, 2023 at 4:50 am

    Nice build.
