AR Maintenance




I know to change springs in my 1911 after so many rounds so my question is how many rounds out of a colt 6920 before you change the recoil buffer spring? Also is there anything else that gets changed after a high round count? Thanks!!!

Every 10,000 replace:
  • Disconnector
  • Extractor
  • Extractor spring and insert
  • FCG springs
  • Firing Pin
Every 15,000 round replace:
  • Bolt
  • Action spring
Every 20,000 rounds replace:

Munch520,

If you don't mind me asking, where is that information from?

Thanks

I do things a little differently, but that's a decent general guide. Barrel length and ammo will play a part in this as well.

Knew you were going to ask that...it's printed off/pasted on the inside cover of my log book. I'll try to figure out where it came from.

ETA: that was easy, my memory is better than I thought it was. Dave runs classes locally and the intervals are from his website, I believe this maintenance section is also stickied in M4C.

I should add that I've had my bolts (from quality manufacturers) need replaced between 6,000 and 10,000 quite often, especially in SBR's.

For my action and extractor springs, I change around 5,000+, but have had to change them with less rounds than that, but those were SS and not CS.

Edit - I typically measure the action spring if I do a thorough cleaning and if it's under 10 1/4", they get replaced. 11 3/4" if it's one of the A5's with the rifle length spring.

Bolts will vary with your firing schedule.
