SIG 516 - Oiling the Piston System

Hey,
I'm soon about to get a SIG516 Gen2 and I am still collecting some final info before I get it. For now, there seem to be 2 major concers for me about the rifle. First is the ammo type that should be used, but it is being discussed in an other thread.
The second is cleaning and oiling the gun, especially the piston system. After doing some research for a week or so, I noticed some opinions that the gun should not be oiled in the area of the piston as it can cause some unwanted glitches or maybe even damage to the weapon.
I would like to hear your opinions about this matter, cause I really need to know what should I do after I get the 516.

Also, the ammo problem I have is with chosing the right type - .223 or 5.56, 55gr or 62gr. Heard that the gas valve on adverse setting won't cause any damage to the weapon (even after longer periods) if it's used with 55gr ammo or lower. Or maybe it's with .223 overall, I don't know. Some people say that the rifle doesn't work properly with .223 55gr and some people don't - I am really confused.

Hello,

Here's some very helpful info.,

The Gun Zone -- SAAMI on 5.56 v. .223 Remington

http://www.sigsauer.com/upFiles/CmsC...ev080910LR.pdf


I use grease on the areas where metel to metel rubs, oil on everything else (like the piston group).

I follow what the owner's manual instructs.

I shoot only 5.56 mm ammo, so far absolutely no problems. It's also a tack driver @100 yds.


Hope this helps.

I've lightly oiled my pistons on any piston equipped rifle and had excellent results. Easier to clean as well. I do clean after every outing though so I can't say this is good practice if a rifle needs to shoot for an extended amount of time or a great many rounds without cleaning. I have never tried either condition with my rifles.

I keep mine oiled. Even the piston. It burns off in the first mag anyway. Went to Militec after the last shoot. Hoping it does as it says and cooks into the metal for longer term lubricity.

Sorry. Just realized I resurrected a dead thread.

Daniel, May I recommend using Slip 2000 products? EWL is your best bet. With this, there's no need to fear unwanted lube on an unwanted area. All the Slip products are organic and biodegradable. No oil or petroleum ingredients of any kind.

I never put oil on the piston itself or in the gas cylinder/tube of any piston gun I own-M14,FAL,AK,M96.

I use mpro7 on the piston area, slight coating helps with carbon buildup. As for ammo, been using 55 grain xm193 from day one and 500 round later not one issue

I concur with federal xm193 5.56. I have ran several thousand rounds with no problems. I use mil-comm products for cleaning. I also use grease on the moving metal parts. I love the 516. Consider replacing the trigger. I have about $800 in options on mine but the trigger was most important. I put a geissle ssa-e on mine and I shoot much better. Good luck. Congrats on your future purchase.

Gas pistons, to lube or not lube, that is the question. First, I am not a "scientist/engineer" and everything I learned is based on experience so it's purely anecdotal. I bought my first semi-auto in 1962. Back then, as a teenager with a $3.00 per week allowance, I used GI surplus lubes and bore cleaner for everything. I lightly oiled the gas piston and it always functioned fine. However, the carbon build up was hard to remove. Several years later, I read a GI M-1 Garand manual and it said to clean the gas cylinder and piston, but do not lubricate. When petroleum based products "burn" the leave a very hard carbon deposit. So for many years, I only lubed the gas piston for storage and "degreased" it before shooting and the carbon deposits were easily removed. Now we now have many non-petroleum based lube/treatments designed for use at very high temperatures that don't seem to cause any problems when used on gas pistons, and everyone seems to have their favorite. I've found none to be "magic" but, when used as per the manufacturer's recommendations, most seem to work well. Prices are all over the place, but usually the higher the performance claim, the higher the price. I guess they figure if you can afford to shoot a lot, you won't mind paying more for a lubricant. Also, keep in mind that many of these "miracle" lubes are part of a "same brand maintenance system", and may not perform well if used in combination with products from other manufacturers.

Daniel: I just bought the same rifle two weeks ago and was wondering the same question. Just decided to just wipe the piston assembly light down with Breakfree CLP before reassembly. You may also consider a replacement aftermarket trigger after you shoot yours. Mine had a 8-9 lb trigger pull that I soon replaced with a drop in CMC trigger assembly. Good luck with your new rifle!

Being a former Gunners Mate I can say this. Clean the piston and cylinder but do not lube. Lube attracts gas fouling and makes the carbon foul up the whole works. If you have the time and energy to scrub the h@&$ out of it, go ahead. An unlubed gas system works good and lasts a long time. I doubt, and pray, you never have to depend on your gas gun to save your life, but if you do, take it from guys that did and don't lube it.

I used to oil the complete surface of my 516 and 716 gas pistons, but stopped doing so.

I did get that burnt - on layer of carbon that's difficult to clean off.

Thinking about it - the areas that are in contact with the hot gas should be kept clean and dry. Quite likely that the very first shot would blow / burn off any lubricant applied there.

Only the areas with the spring and the surface that slides into the receiver hole should be lubricated, if ever.

New trigger in 516

I just bought my Sig 516 and this might be discussed somewhere else, but LoadedRound said a new CMC drop in trigger worked well. I saw somewhere that Sig trigger and hammer pins may be different than standard sizes.

Did you have to put any special trigger/hammer pins in, or did the original ones work with the new CMC trigger kit?

516 uses standard pins.

I used the ''anti walk'' pins that came with my CMC trigger. I had no problem whatsoever with the installation. Just be careful with the roll pin that holds the right safety lever in place. Use the proper pin punches and it is an easy job otherwise you'll be scrounging around for a replacement pin.
