kiwi12 36 Posted December 21, 2013 (edited) Hey, found a M68 CompM2 Optics for the M4A1. Its only a red dot sight but you can attach a battery to it and turn it on/off. Did that with the beginner battery (charged) but i couldnt see a difference. Tested for day & night. Mby someone else had more success?

MrNomadic76 39 Posted December 21, 2013 I have a red dot sight, not even tried attaching a battery, no need, it works day and night for me seemingly without the need. Share this post Link to post Share on other sites
IkaikaKekai 1957 Posted December 21, 2013 It's not working properly yet. So far its always 'on' even without a battery. Share this post Link to post Share on other sites
