I have an opportunity to pick up an extra firing pin and extractor. Should I?

Is it 7.5 French or rechambered to 7.62xNATO?

Solid built rifles. Some of the rifles that were converted have a reputation of having tight or poorly changed chambers that caused reliability problems. I had one that never had a single issue, was very reliable, reasonably but not excitingly accurate.

It can't hurt to have some spare parts if you can get them at a decent price.

The 49/56 firing pin is 'free-floating' within the bolt. The heavy MAS pin was designed to impact French Milspec 7.5x 54mm ammo with tough combat primers-ie: with considerable force. Modern commercial ammunition and reloads have "softer" primers because they are sufficient for civilian use. The heavy steel MAS 49/56 firing pin exhibits sufficient forward inertia when the bolt is released to impact and detonate sensitive commercial primers. (This all happens without pulling the trigger.)

Various unwanted occurrences can result: Slam fires (a round is hurled down the barrel when the bolt is released), burst fire (a couple of rounds fire off to the great surprise of the shooter or
full auto-the weapon just rocks and rolls on until the mag is empty.

Titanium firing pins have proven to be the most direct cure for embarrassing and potentially dangerous slam, burst and/or auto fire in MAS 49/56 rifles using commercial ammo with soft primers.

A Place to order a new titaninum firing pin.

For the price of a new Titanium its still cheap insurance against a future (liable) potential slamb fire and the consequential damage and or death that can result if a round or burst goes off accidentally at the firing range.

If your looking at buying one, you want to check the bolt locking lug for battering, chipping and cracks (very unlikely but possible on worn Vietnam war bring backs or .308 conversions) inside the receiver by removing the bolt and checking it with a flashlight without removing the lug as its staked in place. Also should be nice and tight with no movement.
It should have a nice machined apperance (clean lines)
That may affect headspace.

You can find suitable replacement parts at this sight.

And remember that 7.62 NATO is NOT .308 Winchester.

I heard of an aftermarket firing pin with a spring on it. Any thoughts on this?

The modified french firing pin with return spring.
Item #038: MAS FP MAS 49/56 Firing Pin Kit, $34.50 ben@murraysguns.com

http://www.murraysguns.com/cart.htm

If youve ever tried to drag a file across a MAS 49 firing pin you will most likely dull the teeth on your file.
Id put a return spring on my firing pin by turning it down but it was no easy chore getting the demensions correct the first try (no room for error) I'd a ton of researching the internet, took notes, and got creative in OTZ with a vernieer caliper, power drill, bench grinder and a ACE Hardware sping, dialing up my confidence I waded into dark waters thinking I could always buy another OEM Firing pin if I screwed up.

And Im now out of 1980's surplus Argentine 7.62x51 That I had and now need to scrounge up some more.
It seems The 7.62 MAS 49/56 is like a magnate, it sucked a 7.62 cal Spanish 1916 into my gun cabinet, so now we have two rifles that dont really digest .308, but do ok with 7.62 Nato

The great part about the MAS 49 is the scope mount dovetail.
You just need to attach a cheek piece, possibly a lace one on.
