View Full Version : Bolt Question....

I purchased this Bolt many years ago believing it would make a nice spare part for my FN. Later in life, I thought I'd tinker around with it to make sure everything was as it should be...it wasn't.

Problem is, I can't get a Firing Pin to seat all the way in correctly. I only have a couple varieties to sample with (Imbel and FN) but neither of them fit all the way through.

My guess, is that it is probably a proprietary bolt from a country in which only a firing pin manufactured from that country will fit?

Here is a description of the only marks that are stamped on the bolt:

There is what looks like a number "9" followed by a number "4". Note that the number 9 does not actually resemble a "9" as it is more curved and rounded of sorts. Since it seems like I can't post a picture here, I can email it if you think you might know what it is.

*Also note that it is a Type "B" Bolt (for 2-piece extractor).

Does anyone recognize this bolt and can tell me what the scoop is in regards to finding a firing pin that will fit properly?

Will this bolt work in a metric FAL once I find a correct firing pin?

Well I will start off by saying pictures would help considerably. From your description it sounds like you have an inch bolt, possibly British. Yes, once you obtain the correct firing pin you can use that bolt in any metric or inch FAL, but you will need to redo the headspace. Anytime you switch your bolt with another one you have to redo headspace.

How do I post a photo in here?

Go to Imgur or other phot hosting site and copy the image code. Paste that code into your post.

Ok, I finally settled down and figured out how to post a picture (actually it was painfully easy).

As mentioned in the original post, I bought this bolt many years ago and recently discovered that it does not accept metric firing pins (they will not go all the way through, I tried a couple other metric ones with the same problem).

Here is some various pictures of the Bolt in Question:

#1. Can someone verify what Country of Origin this was Manufactured by?
#2. Does Inch vs Metric Bolts only accept Inch and Metric Firing Pins?
#3. Any other useful information in regards to this bolt?

Much Thanks for Any & All Help!

Bolt is Canadian.....probably worth a small fortune as I haven't seen one come available in many years. You need L1A1 bolt internals, not metric.

Anytime you switch your bolt with another one you have to redo headspace.

If by "Redo", you mean "Check headspace", your statement is accurate.

Replacing a bolt often times Doesn't require a headpace change. Done it MANY times.

But it's always prudent to check.

Thanks for everyone’s help. As mentioned, I bought that bugger in a “Metric Survival Pack” of sorts way back in ~1988. Ironically, it came with an Izzy Lower as well (not exactly the Metric Survival Pack I find I was looking for, but I did score a metric firing pin that fit my FN!! haha)

Thanks again!

Well that's quite a find. Those things would probably fetch $150-200 if you were to sell that on Gunbroker. I'm sure the sharks will be swirling you soon if they haven't already.
