Maintenance / service schedules of rifles

Postby hjensen » Wed Dec 29, 2010 6:39 pm

Hi, I've been looking through the forum for a recommended life spam of parts for the m6 series of rifles. As in after how many rounds should I replace the BCG, or springs, or a new upper because the barrel is toast. Stuff like that. Thanks for all the help.

Life Spam. That's funny.

Here are a few from a quick search:

Barrel: 20k rounds (LWRC target number)
Bolt Springs: 10k rounds (per Darren)
Piston Springs, Spring Cup: 3-5k rounds (consensus)

Not much else to replace, except maybe an extractor if it breaks.

Ha! Like the Spam. I would add action (buffer) springs, I like to change them out about every 5000 rounds just be safe. I'm sure they last longer but they're cheap and its easy insurance.

+1. It's easy to get carried away in "upgrade" fever when perusing websites and such. However, a quick trip to the LWRC webstore is a sobering reminder of how affordable the correct replacement parts actually are. Buy the right spring, change it every x000 rounds, and repeat as necessarry. It's cheaper, easier, and more reliable than buying the $90 uber-spring and loving it too much to change as required.

Thanks gents.
The only thing that bugs me is it seems that the barrel life should be more than 20k rounds. If that is the case then our infantry units in the army should be changing weapons every two years at the most. If the chrome barrels are < NiCor Barrels. Seriously 20k and a new upper? It bugs me because I would assume since it's 4x harder than chrome and has a higher lubricity it would last 4x as long as an chrome barrel. Am I nuts to think 20k rounds is a small cout for barrel change?

Really? What do you think the barrel life on an M4 is? Try around 10K with heavy firing schedule. And when the barrel is shot out you don't need a new upper, just a rebarrel.

and some M4s see even less life expectancy out of their barrels, many as low as ~6800. So figure NiCorr= roughly 4 times the service life expectancy and without the degradtion in accuracy normally associated with chrome bores.

I have seen a Colt 6933 barrel start kicking fliers at just over 5K. This was do to heavy full auto use.

I don't know how long a Nicorr barrel would last under this type of shooting, but shooting semi should get you past 20K.

Thanks Darren that would be awesome.

I guess I am just over estimating what these weapons can do. So if the rifle is usedunder suppressing conditions it's 20k rounds under target shooting conditions then how many rounds or 20k still?

Searched and found this thread.

Is the replacement schedule out there somewhere. I couldn't find it.

Despite the schedule, would 5k rounds be a good rule of thumb to replace springs? Also, re: barrel wear (and I am nowhere near 20k rounds), will accuracy decline gradually as you approach that, or does it just go all to pot all of a sudden.

Forgot to add: is the expected barrel life of a REPR also roughly 20k, or will the 7.62 wear it out sooner than an M6 barrel?

Then I thought: 20k rounds of 7.62 = how much in U.S. dollars? That there would be a lot of SPAM musubi! :!:

I don't think a nice cut and paste schedule ever got thrown out here.
Yes, 5k is a pretty good interval to swap springs. At super cheap ammo prices, that is $1500 of ammo... and $15 dollars of springs (not including trigger pack).
