    Took my new RDB out for its first range day! Mucho fun!!
    First impressions are as follows..
    The night before, I took it apart, cleaned, lubed & ran a bore snake through it. Then off to my local indoor range the next day. No optics yet, so I used a set of Magpul plastic flip up sights at 25 yards using Federal 55 gr 5.56 FMJ out of the green ammo can. That pup is a lot of fun! I noticed the cases were coming out with bent necks & after about 20 rounds I had a FTF. Live cartridge ejected with a bent neck & mashed bullet, so I went 1 click lighter on the gas setting. Spent casings looked much better, but still slightly bent rolling on the workbench. Went 1 more click lighter, now the spent brass looks perfect.
    Overall, shot about 90 rounds with nice groups @ 25 yards. Zero issues after the gas adjustment. Mags & mag release worked flawless. Amazing trigger. Can't wait till next week!

    When you say lighter, were you turning the gas valve CW or CCW from shooter point of view? How many clicks from full CCW is your sweet spot?

    From the shooter's POV, I went 2 clicks CW. (what the manual calls "less gas").
    Sorry, I did not bottom it out to get a reference point either way.

    Youre probably within the typical 5 clicks from full CCW range.
    Keep us informed.
    Just keep adding new comments to this post.

    So week 2 with the RDB went just like the first. Shot 60 flawless rounds in between pistol shooting. Feeding, ejecting & running like a pro. Federal 5.56 ball ammo from the ammo can. Loving it!
