AK47 Front Sight Post - Chinese PolyTech AK RiflePoly Technologies
This front sight post is a direct replacement for the PolyTech AKS-762 or the Legend Series AK47. This same sight post fits all PolyTech AK47 rifles. To install, simply unscrew the existing threaded sight post and screw the replacement into place using one of our PolyTech sight tools Item# 100-019 or # 100-020C. This PolyTech sight post is a standard size, so it should fit most AK47 rifle variants.
Brand new and well packaged
