DRChin's Review of FAB Defense GL-Shock Adjustable Cheek Riser w/ Picatinny Rail Adaptor

If you've mounted a scope, especially if using i.e. -Quick Detach Mounts onto a Picatinny rail, and retained your iron sights, this is the accessory you need to maintain a solid cheek-weld to your stock giving you a better sight picture. The fast and securely adjusting cheek riser enables a natural and quick positioning of your eye to sight line to reduce any parallax errors when on optics, and when the irons might be used, a quick loosening of the twin knurled knobs and slam down of the riser on the guide tracks returns you back to ideal iron sight level. Adjustability is important, especially if your rifle is used by shooters other than you. Made of high quality glass impregnated plastics, the accessory is strong and light. I am not sure what attachments I might use on the dual sided accessory rails, (magazine clip?), but they’re there. Nicely styled, I actually performed some gunsmithing with custom sanding of the interior of the riser mount (meant to fit one of two style telescopic AR stocks) to fit my Ruger TD stock to provide the support I needed, yet retained all the functionality of the original design
Pros:
  • Well made and functional
  • Quick up/down adjustment to afford proper height
  • Space below riser clears use of charger for ARs or cradling of stock with hand per oem
Cons:
  • manufactured to accommodate only two stock styles
Best Used for:
  • reduce that parallax with a high mounted scope
Would Recommend: Yes
