Will an mft tekko handguard hold zero? - MFT Tekko Polymer AK-47 Integrated Rail Systems

MFT who gave us what’s become the universal lightweight Minimalist buttstock has some amazing polymer products that really work.
If you’ve got an AK-47 stamped receiver, this design will allow you to mount a red dot sight that holds zero better than Midwest Industries barrel-clamped design and runs cooler than the Ultimak design that locks down the gas tube to provide a secure rail. It’s secure and it’s a test of your optic to see if it BBQs.
The MFT Tekko holds the rail above - and away from - the gas tube, secured to the lower guard by four stud screws tightened into the bottom guard. It’s like a rail on a canopy held firmly above the hot, vibrating gas tube. The bottom guard is a tight fit, but once the front and rear snap in their notches, it DOES NOT move. It has tabs that look like they’d fit into the top tube flanges, but to reduce vibration you should trim away any part of the tabs that contact the upper guard. It’s less prone to the effects of barrel harmonics because it’s not clamped to the barrel.
It sells for about $40. Compare that with designs that can’t do what the Tekko does.
