The castle nut is a slight different black color then the end plate, it is not coated with the same gloss look. Its more of a matte look and seems like will scratch a lot easier. I also have the Strike Ind. buffer tube in black which matches this end plate color but again not the nut its self, hope ...

Be very aware, that this will remove the most forward position of your buffer tube and the stock will not fully collapse in. For a lot of folks this probably is no problem at all, but it borders on commercial grade. Be aware of this before going to purchase. That being said, it's a good, hard and w...

best castle nut and end plate combo PERIOD

by Gunguy, Verified Owner from RI, United States Written on September 3, 2025

  • None
Cons:
  • None

Does not fit most buffer tube thread lenghts

by MT, Verified Owner from KY, United States Written on July 14, 2025
Everything looks great but regular/normal buffer tube threads are not threaded enough to allow for the extra "girth" of this product. Can not screw buffer tube in enough to engage the buffer detent spring. N
Pros:
  • Looks great and has QD on three angles
Cons:
  • None
Would recommend: No

Expensive bit of kit but worth it to get QD hole and sling loop off the grip

by Dave, Verified Owner from OK, United States Written on April 30, 2025
I love having a QD hole centered behind the grip, but most user know that doing so puts the QD sling loop in the way during right/left, or malfunction transitions. This end plate puts the QD hole and sling loop farther back and away from the grip, keeping it from getting caught during transitions. (I don't/won't use the side mounts, but they came with it so they will stay.) Please, be aware that you will need to use an adjustable spanner wrench to tighten it. A standard castle nut wrench won't work. The "locking" screws don't do much if you don't get the nut torqued down. In addition, it sticks out far enough that you will lose one position on your collapsing stock. Overall, an expensive fix for an issue your average user may not experience.
Pros:
  • Looks sharp
  • QD mount out of the way
Cons:
  • Expensive
  • Lose 1 position for stock
  • locking screws don't work
