21mm rail gun Customers Reviews

  • Plastic rails but it is solid as metal.

    posted by Satain

    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.
  • Fine product

    I ordered this laser for my friend who is an airsoft player, and he claims his efficiency had doubled since he got this and sku 12173.
    It is not obvious which side of the battery should be inserted down, as a result, we put it wrong and thought that the laser was not working. So this is a first thing to check if you suddenly receive a DOA product :)
    It will probably not hurt to have a laser sight on your gun, so getting this one may be a good option.
  • Useful

    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.
  • Sacrificial protector

    -Cheap-Looks great-Protects optics from Airsoft BBs
    -This is a great little thing to buy if you want to protect your expensive holo-sight or scope. The only problem is, it will blow apart the first time it's hit, since it's made of acrylic rather than polycarbonate. It will still keep your glass from being destroyed, but you'll need to replace it if it does get hit. Still, it's about the same cost as those flip-up style clear scope protectors you can buy at Cabella's or other sporting-goods stores, and they won't do a thing to protect your scope! I am going to make my own screen for this out of 2mm polycarbonate, which will definitely stop a BB, and it'll only cost me a few cents.
    Buy it if you want an inexpensive scope/sight protector, but don't count on it lasting. But it looks great on a gun!
  • Okay rail cover

    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
