This is the Texas Weapons System Custom solid aluminum rear back sight: It will fit on any picatinny rail system. It will come in leaf or peep as shown. No fast plastic here. The AK47's have a very low line of sight and this sight matches up perfectly when adding optics to the picatinny rail with the see through tactical mounts.
This unit is sold separately from the TWS Dogleg Cover Dust Cover System.
