Most Helpful Positive Review great product
I have this on my MPX and it looks great with a few other raw titanium parts exposed. Product appears to be sand blasted and is not shiny like some other raw products they sell. Highly recommend this product.

best castle nut yet

by Andrew, Verified Owner from IN, United States Written on August 6, 2026
By far the best castle nut ive tried yet. Its right there with FCD in terms of quality but i think it looks even better. Very nice machining, perfect color of black to match the rest of the rifle too and best of all it is so incredibly light. Havent got a v seven product that wasnt amazing yet, great company!
Pros:
  • light weight
  • Machining
Cons:
  • ummm
Best Used for:
  • holding the buffer extension and end plate on your lower...

Quality manufactured.

by S. Templar, D.D., from WV, United States Written on April 28, 2024
These are extremely light and impossibly strong. Grade 5 titanium has a very high friction rating, so these are less likely to come loose unexpectedly.

Definitely recommended.
