Excellent Improvement on Mil Spec

Written by KimWilliams on Jul 9th 2019

I've been using QD end plates on my builds and really appreciate this improvement. An earlier review mentions an issue I did not encounter. The product is well made and fit my mil spec carbine buffer tube connecting to a Ballistic Advantage AR15 lower receiver. I was able to apply ample torque. The QD end plate is heavy duty, much better than some I have been buying for close to the price for this complete set. I recommend it and will be using it on future builds.

End plate nub out of spec

Written by PN on Apr 1st 2019

I really want to like this product, the price point and feature are amazing. Sadly, in my mil-spec buffer tube, the end plate failed to function properly, the lock tooth does not extend far enough into the thread channel to prevent the buffer tube from rotating when applying proper torque onto the castle nut. I am fairly concerned that the castle nut can back out under use (although the detent should prevent that)--or that the buffer tube can rotate since I could not apply sufficient torque without the buffer tube rotating. This may be less of a problem on the PWS buffer tube designed for this end plate, but it does not function well on my mil-spec buffer tube.
