    Works like a champ! Fits perfectly

  2. Fit like a glove.

    Posted by Unknown on 20th Feb 2015

    It did what it was supposed to with no hitches. It fit perfectly and locked up and released with no problems.

  3. It just works

    Nothing fancy, just a cover. Use on 9mm or 22lr uppers.Works like a champ.

  4. It does what it's supposed to do

    It's a dust cover shortened for 9mm AR use. It works in conjunction with RRA 9mm Brass/Gas Deflector. I Cerakoted mine to match my lower in AI Dark Earth. Mounted on a CMT Tactical slick side upper.

  5. it works flawlessly

    Posted by Scott on 20th Aug 2014

    It mated perfectly to my Rainier Arms upper. Needle nose pliers are a requirement to remove and install the snap ring on the pin.

  6. its an ejection port cover

    needed if using a gas deflector.

  7. Worth the trouble, but proof that evolution never happened...

    Posted by Jason on 4th Aug 2014

    This Ejection Port Door is a pain to install in conjuntion with the RRA 9mm Case Deflector! Proof positive that evolution is in fact a myth, because you definitely need a third hand or tail to get the job done. Luckily, my son provided what evolution could not: third and forth hands to get the door installed. It certainly functions well, and it gives your 9mm build the finishing touch.

    As advertised, good quality product and had no issues with installation.

  9. Got it to work

    Posted by Ben on 5th Jun 2014

    I received this in a box alone with the deflector. Door was bent, so it was packaged that way.
    After working it, I finally got it to act right while installed. So no biggie.

  10. Does the job

    Works great on my rock river upper !
