Ryan is correct. PTL is calibrated within +/-2% of nominal torque, and does not require user to read manual. As we all know, reading manual before using the product is something that is not done on the regular basis. MTD, to be accurate, must be used in accordance with instructions provided in its manual. While MTD is both reasonably accurate and consistent, if used properly, PTL is super accurate and super consistent regardless of way it is driven by the user. There is only one way to use it. Another somewhat related video shot by AtOne provides additional info on how PTL works for FNH SCAR barrel change:

On the other hand, I am simply amazed at a number of various methods people are using to apply torque with my MTD. These various methods seem to work for them anyway, although I truly wish they would utilize their MTDs strictly as recommended by provided instructions.
PTL, in essence, is less expensive alternative to Seekonk T-handle, and is built on the basis of heavy duty industrial grade torque limiter having enhanced durability, accuracy and consistency. It allows people engaged in long range precision shooting to keep rifle zeroed, as shown in Ryan's video, in addition to protecting rifle/scope/mount system from any sort of damage caused by incorrect torque application to the fasteners.
