Home Forums Hunting & Shooting Ask The Gunwriters How often do you change firing pin springs?

I have a remington model 7 that is close to 20 years old. It is on its 3rd barrel, not because I wore 2 of them out but just changed things up. I shoot it more than any other rifle and Ive never changed the firing pin spring so I'm wondering if I should just as a good maintenance practice. If I do change it, what would be the best choice, an OEM replacement or an after market spring? Thanks.

Have you stored the rifle in the 'cocked' position OR have you released the tension on the spring during storage?

I learned yrs. ago to hold the trigger AS I close the bolt, thereby releasing the tension on the spring.......

I have never had to replace a firing pin spring.

Good Luck

Kelbly's recommends every 2000 rounds.

I've changed some of my 700's in the past, probably more from a feel good standpoint than anything. The old ones were definitely shorter as in the link.

Somewhere in my early years of being exposed to shooting someone told me to take the tension off of the firing pin spring as jwall has posted.

Never have needed to replace a spring.

This. Includes the family 99, acquired by my grandfather in 1920, used heavily by him and my dad, still goes "Bang!" every time.

Springs wear out from cycling, not from compression.

I've always stored my rifles with actions open, so the spring would be under max tension(oops, I meant compression). I'm not having any trouble with the rifle, but just wondering if the spring would be getting tired even if it still functions.

I’ve never changed one

After market springs can be more consistent which can improve accuracy. I have not bought into the speed springs and pins and usually check to see if Wolf has one just slightly heavier than factory specs.

Have I needed to replace a spring? No.

The only answer is YES. Constant compression.

Yep.

I have 65 - 75 year old M700's and M70's that I see no problem with their springs compared to newer versions.

I've been shooting bolt action rifles for 40+ years. In the early years I never relaxed a spring when putting the rifle away for any period of time but I do it now. Over all those years I've never found a need to change a firing pin spring.

I've replaced firing pin springs on two bolt-action rifles due to problems. In both instances there were a few sporadic failure-to-fire episodes and new springs cleared up both rifles. The round count/dry firing was very high in both rifles.

Not quite as often as Pelosi has voted in favor of America.

Me either, and I have a couple of rifles that I've had for a very long time. I think that, on a list of things to do, it would be about number 999,000,123.

Never changed out any main springs excepting for a well used 1911. Believe that dirt build up causes most problems blamed on springs. I pull the bolt apart on my rifles every so often and give them a cleaning and light lube.
1911 magazine springs have functioned just fine after remaining loaded for decades. They are compressed a hell of a lot more than your typical bolt action spring.

I've had bolt actions from the first world war to function perfectly. I have no idea how many rounds the rifles fired, but I've never had an issue with ignition due to weak springs.

Think about how many times a valve spring on a vehicle is cycled. Accept for extremely high rpm race engines, a properly designed coil spring is going to be good for 100's of millions of cycles.

It certainly won't hurt anything to replace the spring.

Never changed one even on the old rifles. Guess I don't shoot enough.

Springs, particularly of old alloys, do take a set and this is (should be) taken into account. Springs of modern alloys are better in reliability. You wouldn't want to run a carbon steel valve spring like that.

I have a CZ 527 about 8 years old that a gunsmith lightened the trigger on (too much in my opinion). Last year I started getting more erratic grouping from the bench. It also started following thru or discharging as the bolt closed. I store it with tension on the spring. I put a new spring in it and all was well again. Took a while for CZ to have the springs in stock so wondered if more guns were having problems.

A sincere ? Are those COIL springs - as small as firing pin springs ?
