WTS: Eotech 511 (N battery model) Revision E. Excellent condition, just one small mark on the hood. Very lightly used, no problems with retaining zero or tracking. Only selling 'cause I like my Aimpoints better. Thumscrew mount, no box or manual. $240 shipped CONUS. Certified funds only, price is firm, no trades, no pics at this time. IM if you're interested, first "I'll take it" gets it. Thanks for looking.
