Game changer - Kinetic Development Group Modular Receiver Extension, Compatible w/ all 7.62 & 5.56 SCAR Model

The 6.5" is great, as others have noted. Don't forget your torque limiter. OP has the FIXIT one here and was the best value and precision I could find for this job. Also, if you have any muzzle device, make sure it will fit THRU the MREX before you begin installation. I was able to remove the KDG installed yoke in order to make space for my suppressor mount to fit thru the rail. Line up all your screw holes before you open your Vibratite - the factory yoke is prone to move around when you slide the barrel into the receiver. The rail would get 5 stars if instructions were provided. I checked zero after installation and had only shifted an inch right at 100.
