Best for price

by Gmd, Verified Owner from CA, United States Written on October 25, 2025
I took a chance and paid the $$ for this stock and it was worth the price. So far I have used the magpul mags that work great. The factory REM actions screws won’t fit, being too long. You are better off using hex head bolts (1/4x28) got mine from Ace hardware. Also it came with no stock set screw (I had extras). Also unless you modify the grip, it take the older original AR grips. Otherwise just cut some of the back of the newer grips to fit, as I did.
Pros:
  • Best stock I have tried
Cons:
  • Needs some modified screws

Ultradyne UD7

by Butch, Verified Owner from TX, United States Written on March 2, 2025
Better than expected! Sold on the Arca rail! Glad I went with the UD7 vs the UD5, perfect length for my 24in barrel.
