I noticed there are a few brown marks inside the chamber of my classic green and was wondering if it's a common issue? The rifle is one year old and has had maybe 500 rounds through it. There is no feeling of rust when you rub over the marks and the majority is on the slide rails.
Thanks.
 
ya the bronzey brown stuff in between the side rails and the receiver is brazed in brass (like welding) non issue, allthough there should be none "in" your chamber!
 
When I saw the title of the thread I thought you were talking about something else. Like the first time I opened the case on my flat-top CQB/553. There were "brown marks" alright..... :D
 
Thanks winnipegger, I should have been more specific as to the area, I did mean the receiver, I am really quite new to shooting. I appreciate your input, I was worried I had damaged the rifle. I have started to use the white grease that came with the rifle cleaning kit, is this a good idea? I noticed that after using oil and leaving it in my safe for a while there would be alot of seepage around the locking pins etc.

Unclewalther, thanks for the deal on the quad rail by the way, it really make a great rifle better!!!

Ya thats fine you didn't damage it, its from the factory

I use the grease as well. but i use the oil in the winter. seepage around pins in totally fine (sometimes annoying if you over due the oil). Use the included brush to paint the grease onto the guide rails, onto the "tail of the bolt" (the silver part) and into the bolt carrier and trigger mech also remove the firing pin from the bolt and slap some grease on it too. Remember do not lubricate the boltface, piston face, or the gas plug (gas adjuster thing) prior to shooting (a coating of oil for storage is fine but you'll have to wipe it off before firing). However i would recommend you use the oil on the OUTside of the gas tube as it really is the only place thats prone to rust on these guns.

Last week I went shooting at -30c (before wind factor). I got light strikes and most Win and MFS primers would not ignite on first strike. There's some oil on my hammer spring and my firing pin (or did I grease it?). Next time I'll dry it up before going out.

IVI ammo worked perfectly despite cold and light strikes.

On my M1A I also had issues with grease getting too sticky at -30C.

Searching CGN, the trick really is to keep it dry (or almost) in the cold.

Ya i agree. u barely need lube in this rifle at all. but I've seen a couple guns get wrecked from no lube. (brand new C9A2's metal shaving and what not.) which is not something i'd risk with my 3000 personal weapon. but ya you could prolly skip the oil on the firing pin.

would highly recommend wandering over to sigarms556 forum and read the thread on how to treat a new arrival, it talks about the sig 556 but applies to the SAN 100%. Would highly recommned tossing the white grease and only using Breakfree CLP, to rid it of seapage around the locking pins and safety lever etc, get a can of compressed air and blow it out after cleaning until it runs no more, should eliminate the problem. Do Enjoy they are wonderful rifles.

as a side note, the BCG does not cycle near fast enough or get hot enough to require grease, light film of oil is just fine.

This is probably the worst advice I've ever read on this board.

While you certainly don't have to use the 'Sig' issued grease with the rifle, it is good quality and far better at lubing the SAN rifle than CLP.
Just because the action doesn't get hot does not mean that grease is overkill or not needed. Grease will always provide better lubrication than oils (in this particular instance - please no engine crankcase analogies...)

I think there is only two. Rich LPS has the other. To clarify, it is not a 553. It is a CQB with a 553 gas system.

I don't agree with this at all. Why does the BCG have to get hot to neccessitate grease? Remember this is NOT a DI ar15. There is nothing wrong with using grease man. It stays in place better than oil and therefore will lubricate better because none of it runs off the contact spots. And while CLP is decent it is not like the holy grail of lube for guns remember that it is a cleaner lube and proctectant rather than just a dedicated lube. I know the oil will work (as the gun will run when basically dry) but there is a reason the swiss cleaning kits include grease....

And to Unclewalther: Aprreciate the pics! looks uber-cool
