The can that changed 5.56 QD cans forever! Short-barrel-, full-auto-, Ear Drum-, and budget-friendly. This is the new 2020 version with "Omega"-spec mount adaptor threads, which means if you're already invested in ASR, Quickie, or KeyMo, or just want to use it in a direct-thread configuration, the mount can easily be swapped out with the included wrenches.
