KNS Precision "cross hair" type front sights offer the shooter a front sight that covers less of the target at longer ranges. The .240 diameter CNC machined blackened brass housing offers a large, bright field of view. Standard sights have a .082 long housing. Cross hairs are heat-treated beryllium wire .010 in diameter. Duplex thick section is .020 diameter. Matte. Notes: Screw in to front sight base of AK-47, Mak-90, and SKS rifles (Mfg claims is should fit all national makes of SKS, but can't guarantee it)
