Not direct fit for CZ 712

by CZ, from OR, United States Written on November 12, 2022
Does not thread all the way down on CZ 712. Does not secure the foregrip. Also, the clamp that it comes with does not space the tube and barrel far enough apart so the gap near the end is noticeably smaller than where the tube attaches at the end you plan for buying a new clamp. The packaging for the one I got actually has CZ 712 crossed out with sharpie. I'm still using this tube because it's still the best option over getting a Remmington 1100 tube and cutting down the threads on my gun. I ended up 3D printing a spacer so that it would secure the foregrip and that only took about 15 minutes.

Long story short if you are planning on putting this on a CZ 712 it is still probably your best option but be advised you will need a spacer to in between it and the handguard that you will probably have to make yourself and a different barrel clamp.
Pros:
  • Not a lot of other options
Cons:
  • not direct fit for cz 712
Best Used for:
  • people with manufacturing capabilities
Would recommend: Yes
