out the box

by James Page, Verified Owner from TN, United States Written on October 19, 2024
Works out of the box. These are sturdy and of good quality have them on two builds already purchased another one for a 300blk build. Works flawlessly on the 223/556 and the 7.62x39 with 5.5 inch barrels. Only down side is that they don’t come with a castle nut and end plate despite that I still recommend!
Pros:
  • sturdy - looks great
Cons:
  • None
Would recommend: Yes
