The right part for the job... (18/11/2011)

It's a Colt castle nut. I have used these on several custom projects. Allows proper torque and staking of the receiver end plate. These always thread on with a tight fight to quality receiver extensions.

Don't settle for questionable aftermarket parts, especially with the low-quality parts of unknown origin that are floating about.

excellent product from Colt (20/03/2012)

If you're replacing this part or building an AR you should install this extension nut from Colt. This product is top quality and it's mil-spec to boot.

Aesthetically Displeasing (06/05/2015)

I was going to give it a 5 star but, here is the reason why I only give it a 3 star. I choose colt mainly because of its good reputation. I received the product in a bag, oiled, and looks very tough, however it has scratch on the finish. It's minor and its aesthetic but I paid extra to get the best quality, I was disappointed. Returning it is not worth the time and shipping cost.

Colt all the way (01/03/2017)

I only install Colt parts on my 6920. I am to replace an endplate with a single point sling endplate and I just grabbed this one just to make sure as a spare if ever the current nut is messed up so I can finish the job the same day.
