5 reviews for GR21 Rail for the Glock 21

  1. A.J. Kritzman

    Works as advertised. Can’t ask for more than that. Easy to install and just as form fitting as the Recover Tactical rail adopter for the Gen 2 Glock 17. So, breath new life into your Gen 2 Glock 21 by giving it the ability to accessorize like its younger brethren. Don’t be left in the dark!

    (Original) Kann man nur empfehlen, absolut passgenau sieht gut aus und das wichtigste es hält.

    (Translated) I can only recommend this product, absolutely perfect fit, looks good, and most importantly, it does what it’s supposed to do.

    I can finally put a flashlight on my G21 gen1, great product love the design and fitment. Works perfect with 45acp but when I switch to my .22 slide it binds and doesn’t allow the slide to close. Another issue I came across is no options for a case other a custom case . they sell cases for the g21+olight PL mini 2 but the the adapter on there it lowers the light down an additional 1/4 in or so… Recover Tactical has a slick clip holster but with the addition to that the light would have to relocate..

    Fast delivery, fits perfectly and looks great. I’ll be really happy if and when Olight sends the laser/light I ordered more than two weeks ago…

    It fits the G21 perfectly. Took all of 5 minutes to mount. I installed a tactical light with laser on the rail without issues. Nice tight fit with no light shake/movement. I really recommend this if you want to put a light or laser on you smooth frame Glock.
