I've owned a few dMR's
SR25 upgraded to the nuts (don't reccomend parts are a bitch to find
G&P custom built mk18 with real steal 1-4x
Yet my systema TW5 with 7.5" barrel outranged them all, only one that shot better was my PTW 14" and that was because Az tinkered with my hopup and has a real tackleberry motor.
If your going for look all the power to you same with a unique rifle just be aware you may not be able to upgrade it fully do to proprietary parts and depending on barrel cut Rhops and ERhops can because a chore.
