    It's been a long time since I've been on here and I apologize. I am seeking experience and knowledge. I own 3 DI ARs and the Sig 516 is peeking my interest for first piston AR. Does anybody have experience with the 516 and if so I'd like some opinions of the rifle.

    I have a SIG 516 ( among other hi end AR's) and its one of my favorites.

    Tho I am right handed I still like the ambi mag release the the mounting hole in the lower for quick release sling.
    The adjustable gas valve lets you change your setting if you are shooting low powered ammo ( think tula 223)

    Barrel is CHF.

    A fine rifle. Nose heavy compared to a DI AR15. The only rational reason to choose it over SIGs own M400 is using a suppressor. Cleaning is a zero sum game- less fouling in the chamber but a dirty piston assembly. The gas valve is otherwise of no use to a civilian shooter. Tula ammo in .223 will cycle with normal gas pressures, it does not require valve adjustments. (Shooting steel cases from the rifle you paid for is debatable but is not the topic here)

    I have 2 M400s that I am very fond of. I set a trust for NFA weapons and mods, and I wanted the 516 to suppress and SBR.

    Closing the gas regulator will turn the 516 into a bolt action rifle, very quiet with a can on. It is like having 2 rifles in 1, a semiauto carbine for off hand drills, and a bolt action compact rifle for precision shooting. Then you can have a red dot and a scope, both QD, and you got an all-in-one can-do package.

    Sorry Tikki, Sig is better then HK. Of course, Hera Arms is better. I shot all three brands before making my decision. Yet, you can not get Hera Arms in the US. So, I would next choose a Sig Desert Patrol. Accurate as hell. Not as front barrel heavy.

    The adjustable gas regulator gives me a lot of peace of mind for SHTF ammo.

    I recently didnt clean the inside of hte rifle for over 1000 rds and other than the excess oil, it had no caked on crud at all.
    Everything was just spray and wipe.

    last nite I took off the piston system .
    Not cleaned for 2000 rds , I should have taken pics before I cleaned it but it needed hardly any cleaning at all.:)

    LWRC is also real nice but the main thing they have on the SIG is the NiCorr vs chromed barrel treatment.
    The lower on the SIG is very feature rich and nicer than most other AR's.
    Am looking to replace trade the LWRC lower on my LWRC with a Sig516 lower, rght now actually.

    I really do think the SIG 516 lower is one of the best money can buy.
    I forgot to mention the best part too!.
    it has pressure pins that act against the takedown pins to stiffen up the rifle as a result NO AR slop between upper and lower :):)

    Added another pic.

    PS: I do like my LWRC's better but only a bit and they do cost almost half again as much :)

    Is there any slop or play in the rail system?

    There is no play in the rail system, but like most ARs there is a very slight amount between the upper and lower. They are great guns. Like others have said, they are a little front heavy because of the piston. A lot of sig 516s require a break in period to be able to use steel ammo on the regular setting, but you can always open it up to the largest port if you really want to. Just dont do the largest port with regular or more powerful ammo. It will wear out the gun. Also, the irons on it are OK but not great.

    The rail forend is tight. It is integral to the upper and not replaceable within the manual of arms. The sights on most 516 have been BU only. It is a flattop red dot ready.

    I would walk out the store with the Sig. No buyers remorse either.

    I still rank the LWRC a little higher since the barrel isnt gov't cut and it has the NiCorr instead of chome lining. But the SIG certainly is more feature rich than the basic LWRC M6A2 and has the nicer lower.

    I have never seen a Sig rifle in the LGS repair shop. The gunsmith owns one, he never repairs the. I did not buy one because I wanted the Hera Arms AR. German AR are extremely high quality and very accurate. I can only speak for the Sig though.
