does any one have any issues with slight buffer tube rotation? like a 1mm left or right, makes me feel like its not tight. the buffer tube came from a kit with a buffer and spring and a MOE stock off ebay, have no idea which brand the tube is, its like the groove the end plate slides into is to wide OR the end plate notch is to small?    thanks!

Unscrew the lock ring.

Retorque the ring and stake it in place.



If it is loose, the endplate will dig grooves into the tube. Maybe even allow the buffer retainer to come out of the receiver.



Easy fix.

I had the same problem on the first AR I built as I used the mis-printed 40 in/lb of torque.  After I loosened an re-tightened to to the proper torque (40 ft/lbs) no worries and it will NEVER come loose.

Watch as you torque (or have someone else do it) to make sure your stock doesn't rotate if the tube and end plate don't fit tightly.  I didn't do that on one and it is canted slightly
