Works fine
Really great to have a "mil spec" part that works fine for a reasonable price. My first AR and effort at getting one operational. It is fully functional after this and a few other parts learned to be important from Brownells. Thank you.
Good to have on hand as spares
Good to have one or two on hand as they do get lost easily.
Quality part at a good price
I work at a gunstore that offers minor gunsmithing and parts as one of our services. This part is one of the most lost parts when our customers are assembling or working on an AR-15 platform gun. I keep them in stock for that reason. This part fits perfectly in any standard pattern AR-15, and performs flawlessly. I recommend you have a spare or two on hand.
Retainer
So it broke after the first discharge, it may not have just been the retainer.
