It’s the little things……
I replace all my cotter pins with these. No fighting to reinsert. Must have for those who actually maintain their firearms.

It's good
So much easier to put in than the factory one that comes with it. Seems to be holding fairly well. Will definitely be replacing my others with this!

Good but...
It works however, this is my second as the first one broke. Broke down the rifle (LWRC) and it fell right out. But they do work well.

Bomb diggity
Exactly what I was looking for. Replacement for the crummy cooter pin. This is very easy to insert and it’s backed by lifetime warranty, so if it breaks under use, you’ll get a new one free :)

Ditch the cotter pin and get this instead!
Most folks don't know that Eugene Stoner designed the AR15 with a steel pin holding the firing pin in the bolt carrier group. Then some bean counter at the Pentagon (or some other idiot) decided to replace it with a pain in the rear cotter pin. What's the difference? The steel retaining pin slides right in, first time every time. The cotter pin becomes a lesson in frustration if slightly bent at the tip. Life's hard enough, so save yourself some hassle and get this pin from CTD. Trust your old platoon weapons sergeant.

Great Quality and Extremely Fast Shipping
Great Product. ARs should just come with this pin from factory.

I absolutely would purchase this product again.
Purchased five and within about two minutes all five were installed. Just be careful of the first install, line up the retaining pin for the hole on the opposite side of the bolt carrier group and slide it straight across to the opposing hole. The appearance of the new pin looks great. Tool steel, should be a no brainer.

Does anyone have a picture of this in place? The round end seems like it would effect bolt operations.
Answer:
It actually rests better inside the cup milled into the bolt carrier than the standard firing pin retaining pin.
