I'm going to a local gun show on sunday, and I'm looking to put togher a spare parts kit to put in my gear. What parts would you reccomend, and could you give me a ballpark price of what they should cost(so the carney basterds at the show dont rip me off!) Thanks for the help!
I try to keep on hand a complete lower parts kit, (minus the pistol grip)...
Extra bolt and extractor along with extractor spring and pin...
Firing pin and cotter pin...
Basically, just about all the small parts... But that's just me
+1 on the small parts for spares.I have a hollow grip that I carry a spare Bolt,firing pin and retainer,disconector and cam pin,with a cut down to fit the grip 5/32 pin punch for the lower.
try to keep at least 10 spares for springs, since they are the only things that really go out.
I believe Bushmaster has a Spare Parts kit for sale on their website, they use to anyway. It'll give you a good idea of what should be in a kit and how much to spend. IIRC, the price was pretty darn good so that might be another option instead of trying to piece one together.
There are spare parts to keep in your shop, which require tools, vise, etc.
And there are spare parts to keep with your rifle, which you can change with nothing more than what you may carry in your pockets at all times.
For a spare parts kit for your rifle:
Firing pin retainer ("cotter pin")
Extractor, ext pin, ext spring
Two sets gas rings (total 6)*
Hammer pin (also fits trigger)
Disconnector and spring
If you can manage it, a whole bolt is good.
Spare parts for your shop:
as per above plus
Ejector, ejt spring, ejt pin
various detents and springs
entire Fire control group
(Easiest to just buy a Lower Parts Kit, an Upper parts kit)
Gas tube and pin
* Gas rings: While I like the McFarland type rings, they are quite stiff when new, and will require a mag or two to break in and smooth out. There may be some feeding problems due to the stiff bolt at first. Conventional gas rings will not be stiff like this, and the rifle will function smoothly with new rings. So, if you must fix your rifle and put it right back into use, conventional gas rings would be better.
I have finally located some Lone Star Ordnance Stowaway II grips, and will be putting these on the few of my AR's that don't have them now.
