Most Helpful Negative Review Zenith zf-5p
Be aware, I had to drill out the holes with a 5/16 drill bit to get perfect fitment.

Hope you have a drillpress or mlling machine.

Had to mill out the pin holes then mill out the rod holder. the buffer is 100% useless the spring compressed stops it from coming close to the buffer. Once I spent 3 hours trying to make it perfect it fits like a dream. Love midwest gear but this one you need to put some work into it to make it work right. should be 40$ for all the extra bs you need to do to get fitment.

Mac5k Great Product

by PatrioTexn, Verified Owner from TX, United States Written on October 30, 2025
Love it. Very well made. Keep in mind it will need modification. Use a .308 bit to widen the lower hole. ( The hole nearest the grip ) Zero play. Moving forward the lower pin will need to be removed with a mallet. ( Not difficult ). PatrioTexn.

Very hard to reinstall pins after mounting.

by Islander, Verified Owner from UT, United States Written on January 10, 2025
This backplate fit into the frame fine and the holes looked aligned but the two pins would not go in. Used a rubber mallet and took many strikes. The top pin knocked out the outgoing washer that was welded on.
Pros:
  • Worked for the brace I put on
Cons:
  • Very hard to reinsert the two pins
Best Used for:
  • Attaching a folding brace
Would recommend: Yes

MIDWEST INDUSTRIES MP5K 1914 END PLATE ADAPTER

by Charlie, Verified Owner from LA, United States Written on January 7, 2025
Thanks Optics Planet. MIDWEST INDUSTRIES MP5K 1914 END PLATE ADAPTER arrived at the perfect time. Just received my TAX STAMP before I could install the end plate adapter. I had to do modifications to the upper and lower pin holes to get a perfect fit. I’m definitely happy with this purchase as I’m able to change to multiple stocks that I own.
Best Used for:
  • MP5K
