spare bolt. (they break)
spare (get a load of this) charging handle latch PIN. Pat Rogers stated that this oft-overlooked part is a COMMON failure in his carbine courses, especially on AR's that have "tactical" latches, which exert more leverage on the pin.
spare firing pin retaining pin.
And if you are running anything other than a standard buffer and spring, make sure you also have the spare STANDARD spring and buffer in your gear bag.
and while not SPARE PARTS...one of the MUST have's on my list, is 3 tracer rounds hid away in the storage compartment of my MIAD grip. Neva know when you might need to blow something up.
This is the only area of AR-dom where I regret buying a lefty Stag. As far as I know, the only parts that won't match up are the bolt and bolt carrier. Does anyone else know of other nonstandard parts on a lefty Stag that I would need to get directly from them? I assume that the firing pin, retaining pin, and the bolt cam pin are the same, but I'm not sure, it's my first AR so I don't have another one to compare it to.
you got me thinking on this one.I have never had to replace a part on a AR-15/M16 ever.over the years in the army I can say this about the ones I was issued and everyone was well used and abused when I got it.the A2 was my very first "new" issue rifle.it was sweet.I put a bunch of rounds through it never had a failure with it.I was a RO for my unit so I went to just about ever range detail with that for 2 1/2 years.any ammo left over was always shot up and the brass turned it .
