I am new to the AR world Stag lower with a m4 1-7 5.56x45 upper. My ? is field repair kit I see advertised my thoughts were they don't brake down. So do I need to get one to have on hand. Can anyone tell me when they needed one?
 
Well, in a SHTF scenario, you're better off with more extra parts than you need. And if you're putting 5,000+ rounds through it a year it is probably not a bad idea. I shoot less than 500 rounds a year through my AR's (although I do put thousands of .22's through them each year) so I'm not worried. But I'm also not too worried about the end of the planet. My AR's have been extremely reliable with the few thousand round they have fired. Stag is a middle-to-high end brand. If you want to spend more money for the peace of mind, go at it. If not, don't worry about it.
 
Thanks for thoughts on the matter but wonder about how many rounds can be shot before springs or firing pin has problems.Can some one share you experience with this problem if it is one?
 
I think a lot depends on the quality of the rifle and how you use and clean it. The buffer spring will wear over time but a high quality spring will go longer than a cheap one. With quality parts, I suspect you'll shoot out the barrel before you need to replace the spring. The AR is pretty reliable and as close to indestructible (assuming it is maintained) as you are going to get but parts will wear over time no matter what. The attached manual includes detailed maintenance and repair schedules.

I keep a set of all springs and detent pins in the event I launch one in to low earth orbit while cleaning.

I keep a lot of other spare parts and they turn in to complete rifles after a period of time. Added two complete rifles and one upper this year.
 
Thanks Swamp Yankee thats a lot of good info it will keeping me reading a wile.But do you know of some one or even your self having to replace parts in a AR?
 
Only parts I have replaced were ones I lost (I learned to dismantle parts with detent pins under spring pressure inside a dry-cleaning bag) or ones I think someone screwed up, EXCEPT for a cheap extractor -- you could see how poorly made this piece of sheet metal was.

If you believe it is possible that someday you may be unable to buy a spare part you need readily, if at all, BUY generic repair kit NOW and leave it scrunched up in an inexpensive MAGPUL closeable pistol grip. In fact, you could eliminate a few components because some are used in more than one spot.
