    Good product, but...

    It's a great product, but it came in a plastic bag with no instructions or information about the lifetime guarantee Primary Weapons Systems offers on this product. I contacted customer service and got a response back saying they order them in bulk, so there is no retail packaging available and gave me a link to a Brownells video showing how to install it.

    PWS Ratchet Castle Nut & Endplate

    Posted by Hunter on 10th Dec 2019

    Exactly what I was looking for. I like to stake all my builds but a buddy recommended checking out PWS' system and so I did. Now I don't have to replace my endplate or castle nut if and when I want to replace my whole buffer system. Very easy to use obviously swapped them out in 5 minutes on 2 rifles clicked them a few clicks tighter than hand tight and it won't budge without a wrench.
