gun shop has a used SAR-1 has an ultimak gas block rail and a used EOTECH (AAA battery? not the N battery) it does has the F in the lower corner with a couple of chips in the metal hood. all for $595 (no tax up here) i am thinking the sights are $300, rail is $100, so an AK for $195? decent deal? maybe i can talk em down to $550?
