I am getting ready to purchase a Eotech 510 for my Bushy M4 and need some help on which A2
handle mount I should get between the adjustable BC-CAM or the PRI Cantilever mount to get a
proper co-witnessing setup. They both claim to position the sight on the proper co-witnessing plane, so is the adjustable necessary ?
Thanks B D
A.R.M.S. also makes a adjustable carry handle mount. Does the adjustments make a difference? Don't know. I just got a flat top upper receiver instead. You may be able to find someone to swap you for your carry handle receiver with a flat top one on the Equipment Exchange section of this site. Then you can add a back up iron sight so in case you run out of batteries or your red dot breaks. Just an idea for you.
