Solid rail mount. have tried cheap and inbetween but this was worth the money! - Texas Weapon Systems AKM/AK-47/AK-74 Gen-3 Dog Leg Scope Rail Top Cover

Easy to install. Took under 30 minutes. High quality machining and parts are well made. Retainer ring bent but I replaced easily. Holds zero and allowed me to shoot sub moa 50yrds (3rnd) and moa-1.5 at 100yrds. If you are building an AK like I built this is the rail to get. It holds a American Defense Scout Rail and Nikon scope or Vortex RDS depending on how I feel. Well worth the money. If you are not mech inclined have someone else do it for you...It was EZ for me.
