I had to order a new set of , M14A1 pliers because the set I bought from eBay bent and messed up my Nut so I ordered the nut and pliers when I received my order which was very fast delivery time like 3 days 😀
I put my Rifle in the vice and came loose like it Spos to ( I don't think 🤔 it hasn't been removed since 1960's )
So I definitely highly recommend buying from MGW Great prices and shipping
Definitely going to buy another set of pliers
For my brother

Perfect replacement for the original castle nut, finish matches the new threaded adapter replacing the factory muzzle device, no complaints. Threaded clean and no problems getting everything installed using the castle but pliers also sold here on MGW.
