Firing Pin retainer pin

I've been familiar with this platform of rifle for the past forty five years. I was also an armorer for my department. So I was surprised when I pulled this pin out for cleaning, then couldn't get it back in. I tried everything and it was just not going to go back in. I bought these and it's all good again. YES, I had to do a little fitting, but it did work. I'm happy with these and would buy them again.

Firing Pins for AR

All 5 pins fit my S&W AR but required a small adjustment. Put a small brad between the pans and compressed the tips with pliers. Good to go.

Always good to have on hand

Simple product, as expected.

One star for each pin.

The purpose of this pin is simple, keep the firing pin inside the bolt carrier group. A task for which it performs exceptionally well. Plus there are 5 of them so I have spares for when my non-dexterous self drops one somewhere. The very problem that made this purchase necessary.

Good Buy

Good fit, reasonable price, they work. Nothing else needs to be said.

Great Extras

Nice price to have extras. You never know when you'll need them. All of them fit in three different GCGs without issues, no fitting needed.

STOCK UP!!!
