Firing pin snapped in half

PLUS This ^^^

All in good fun, Stickman is good people.

They also sell more than all other manufacturers combined. Measuring complaints by how many people that post on the internet is a terrible metric. I’ve yet to meet another shooter on a range that has even heard of M4C.

Typical silly comments here in a PSA thread.

Well, PSA is a meme brand so it’s fitting I suppose.

Exactly. Good firing pins are cheap.

yep. And they account for a good percentage of improperly assembled trash and parts on the market.

OP if you contact me by PM I would be happy to send you a couple firing pins as I am involved in the manufacturing of to print MIL spec M16 firing pins. I believe the issue is related to material type and heat treat process or lack there of. These are very critical areas and processes and in most cases not followed by most. Straightness is also an issue and a spec that is called out that most firing pins will not pass because its hard to measure and many so called rifle manufactures simply dont have the equipment to confirm or take the time to insure what they are buying.

Honestly if its cheap or what one might call a really good value (cheap$$$) then you can pretty much assume some corners have been cut. Is that good enough? Only you can decide and know many companies think on the inside about just how many rounds is “our” customer going to shoot a week, a month and a year for how many years. Yup that’s good enough and worth the savings and we can replace the defective parts by playing the odds. If you need an example just look at your favorite value Red Dot company offering a lifetime warranty with goods made in China. I say company and not manufacture for a reason.

I have spare firing pins, cams, extractors and extractor springs, firing pin retainers, etc. Also have few oops kits for the lower receiver as well.

Thank you. I just bought a couple FP from a top vendor and honestly can see a big difference on it. Is even a tiny bit heavier.

While I’ve never seen a broken firing pin, anything made by man can fail. As long as you’re reassembling your weapon properly, I wouldn’t give it a second thought unless it happens again.

After a closer look at your broken firing pin and your comment about weight I believe the pin that broke was an AR15 firing pin and not a MIL-SPEC M16 pin. The M16 pin has a larger diameter flange. M16 pin is not necessary but it does point a bit to a possible sub par or spec item because it doesn’t have a spec that it has to match.

My first thought also. Reason new to AR first time resembling it.

Deff possible, is my first rifle. Thanks to all for the replies. I just wanted to add that I’m still very happy with PSA and this rifle. PSA shipped everything very quick and even though they took a week to reply to my email, they did and sent a replacement firing pin. I’m not a operator and this rifle is not for home defense either ( I got neighbors 10 feet on each side of my house). For my intended use for this rifle is a strictly range gun for max 200 yards. My budget was a$1000 so I decided to spend in $500 rifle plus ammo, magazines and a optic. For my intended use for this rifle I believe PSA is great. In the future I’ll prob upgrade the barrel and the bcg. Thanks all

Well, did the rear half fall out right away or did you have to remove the cotter pin first? This would answer the “what happened” question.

I had to remove the cotter pin to remove the rear piece

The OP said the rear piece was rattling around…like broken off, and rattling around loose. How could it be rattling around while held captive by the cotter pin in the bcg?

The side that hits the primer was the piece that loose through the rifle when I pick it up. The side that gets hit by the hammer stayed till I removed the cotter pin.

Interesting. If I’m interpreting what you are describing correctly then the firing pin must have been installed correctly and just broke due to poor quality. Good call tehpwnag

It is what it is. No shame if it happened due to improper assembly (chalk it up to a learning experience), but it sure would go a long way in explaining what the heck happened.

During dry fire, the shaft of the pin has no opposing force except the mass of pin itself. So, for the front part to separate from the rear is quite odd. When I read P2000’s original hypothesis I said to myself “Yep, 100%”. Not to beat a dead horse though.
