When do you replace the operating springs in an AR?
Buffer tube, fire control, extractor and ejector springs.
Is there a written rule for rounds fired and replacement.
Thanks

The next question is, are all spring created equal? The answer is a 100% NO! All springs wear out, but some materials do it slower than others. Chrome Silicon (CS) springs have a much higher life span than SS springs. They take a set the very first time they are used and never again. For this reason, I recomend them to be used in mags, extractors and buffer tubes.
There are also different levels of CS springs. A company called ISMI makes the very best CS springs on the planet IMHO. Their springs are shot peened, stress relieved and have a 1 year warranty! I have changed out all my buffer springs with theirs and noticed a diference in felt recoil over my old spring. The down side to these springs is that they are expensize. ISMI buffer springs run at about $18 a pop. SS buffer springs are only $5.
A simple and good test to see if your buffer spring still has enough power in it, it to take load up a 30rd mag. Lock the bolt back and insert the mag. Hit the bolt catch and see if it was able to strip a round off the mag and FULLY insert it into the chamber. If it cannot, it is a good time to change out springs!

Here is a pic I took of a used buffer spring and two new ones. You can see how use really shortens the SS spring.
Too bad they dont make Mag springs. i need about 4 to replace teh springs that went tits up in my Sig 229 mags. I got 4 from CDNN and about amonth or so later all 4 springs quit. I had thought about buying one of the ISMI springs to replace the buffer spring I have now. I have about 3000 rounds through my RRA.
Grant would the ISMI spring work well with an Enidine Hydraulic Buffer?

I run the ISMI with the Enidine and works just fine.

So do you carry the springs for Sig mags? Or where do I pick those up.

Along the issue of mag springs, don't they also make springs for Glock? How do C Products springs compare for AR's/M16's?
