I considered the Daniel Defense MFR XS and the Bravo Company MCMR before settling on the Geissele. Ultimately, I chose the Super MK8 because of Geissele’s reputation for unwavering quality and the MK8’s slim profile. The 2″ barrel nut design also seemed to offer enhanced rigidity, which was a key selling point.
