21mm rail gun Customers Reviews

  • Useful

    posted by Blademir

    This adapter is very good tracks. For those who have weapons with 11mm rail and wants to adapt to 21mm is great. But it's even better because it has two side rails 11mm to install lasers or flashlights, and its top rail can also become 11mm, simply remove the top piece, simply remove the two screws. Cheap price for gun prices.
    Impressive quality.
    Simply and Useful. Improved the look of my airgun.
  • Okay rail cover

    posted by FreeUsername

    Flexible and soft rail cover, easy to put on and off, it can be cut into smaller parts to cover a longer rail like the HK416 rails or M16 without being able to see the part where it was cut.
    Allthou i ordered beige and i expected that color, because it was in the title, description and elsewhere, i got black.
    Nothing left to add, it`s okay and that counts. Now i have to add more words to get the 500 character limit.. geez, DX didn`t let go off that rule yet
  • Small and good

    posted by UserFromCH

    Small. Would fit well in gun and rifle.
    Survived shooting full-auto firing with an AK47.
    Wide range of correction during zeroing.
    Allow to add another device on its top. Like a small red-dot pointer.
    Strange feeling when zeroing. The laser movement wasn't linear with the screw movement.
    The laser could be brighter.
    Good small product. Not expensive. Try it.
  • Great way to protect you red dot/scope

    - Easy to mount on picatinny rails- Well packaged- Two film covers protect the hard plastic lens- Two color lenses
    Great piece of kit for airsofters. This will protect your red dot/scope from hits of bbs. I've used this lens protector during a skirm this last weekend and it held up flawlessly. It's easy to install close to the, in my case, red dot and does not obscure the view you need. If you are engaging at longer range and you get some glare of the lens protector you can easily flip it down out of sight.
    Great product, great price! Protect your red dot/scope from being broken by a BB by installing this lens protector from DX.com.
  • Plastic rails but it is solid as metal.

    Great Price.Works with all 1913 and pictinay mountable stuff.Comes with everything to attach it to your rig.
    As long as you are mounting non mision critical stuff on it like light, bi-pods or fore grips you are good to go.
    But this for a mosin nagant rifle with a promag stock so I can mount a bi-pod on it and for that this product is perfect for it.
