This is a TWI brand replica B10m lower rail handguard for AK74 & AK105/4. This is hands down the best quality replica zenitco brand I’ve seen. It’s CNC machined out of the same aluminum as the original and the details and script are perfect. I say this because I own a real Zenit B10m. The only difference between them is the TWI has a better kind of brushed txtr finish(that many zenit grips have). The quality comes at a price as I’ve yet to find one of there b10s outside of Asia and they retail for the same price as original zenit at most sites~ $100-$110. TWI’s parts are made for LCT/GHK aks but because they’ve designed a removable rear piece this rail will also fit tm spec and other aks w/o mods PP only HMU w/ any questions
