    1st review

    What can I say it’s light, easy to maintain (MUCH, MUCH, MUCH CLEANNER than ar/m16!!), more accurate that my m4, more comfortable to shoot. All around better feel than any of the AR/M16 style rifles I have ever handled. The only issue I have is the polymer front rail system found on the current models. I would have rather paid more for the metal rails that are offered on the swat model that is nearly impossible to get. Price is high but I think in this case you are getting what you pay for.

    Outstanding product. As accurate as any high quality AR, and more reliable. For accuracy, it likes heavier grain bullets (62+) best, but will eat anything you can fit into the shell casing. This is the only reason it didn't get 5 stars from me. The factory 2-stage trigger is the best non-custom trigger I've ever pressed!

    If you closely look at the machining that was involved, I believe it would be cheaper to mass produce for the military than the M16/M4. It breaks down simply, the handguards are solid, and there's no twanging buffer spring. It has all the best aspects of the AR and AK rolled into one.

    Compares to the best M-4s I have owned but simple operation and tear down. Likes TAP 75gr or 69 gr for best accurrancy trigger almost as good as two stage RRA Tact. Entry I own. Yes the foregrip w/o metal rail is a drawback.

    Seems to be a good solid weapon only drawbacks are:
    1. Poor or no backup iron sights
    2. Rails should be steel not plastic/polymer.

    I havent got one of these yet, but im planning on it. Its apretty much the same thing as an ar-15 even the disasembly. When i get one im going to put a ecotech or somthing like that on it since its back sight is only put on one position. But its a great gun.

    I have just purchased one and the first thing I noticed is it's durability. It is made to take a beating while remaining reliable. This is one of the best gas piston rifles out there.

    Own this rifle. Better then the ARs /AR clones that are out there... only draw back is it needs metal rails.

    This is what our tactical team uses now. I would trade it in a heartbeat if I could. Very picky with ammo. Supposed to use the 75 grain bullet which is very expensive. Very heavy for a tactical weapon. The built in picatinny rails are nice to have for mounting extras. The trigger is nice and smooth. Those are the only two good things I have to say about it. (Oh yeah, and it didn't come with sights!)

    I LOVE IT!!!! I have the HALO version. When you add a light, lazer and pistol grip to the front, it gets a tad nose (muzzle)heavy for what I like. However, recoil is more controlable. Still, its a SIG!!!

    I own and carry the SWAT version, which has the quad rail. Superior accuracy. Well built and in my opinion far exceeds the AR15/M16 platforms. Had a Bushmaster, whcih has since been sold, because I was so impressed with the performance and quality of the SIG.

    I've shot this next to an M4A1, everything about this gun excels and is far superior to the M4A1. No more brass hitting your buddy next to you, the casings go out to the right. VERY accurate, with the red dot scope I was hitting things dead on target from over 75 yards. I would take this rifle over the M4 or M16 any day.

    We bought each officer one of the swat rifles, they very reliable weapon. But they are heavy which can become a factor in a prolonged standoff. The factor sights aren't very good. Both front and rear sights are flip up and if your not careful the front sight will go too far forward which will affect your accuracy. But are very accurate with aftermarket optics. I'm here to tell you that the look mean if your on the other end. As far as the mechanics of this weapon I cannot find anything wrong. It fires every time you squeeze the trigger.

    I bought the SWAT model and like all SigArms, it is perfect. It is based on the Swiss 552, only this is made in the USA.

    With the SIG $300 rebate, this rifle finally came into my price range. I purchased the 556 classic. Has the look and feel of the 552 but accepts AR style stanag magazines. Perfect for the American shooter. The dual rotory diopter iron sight with co-witnessing red dot sight is an exceptional feature. My biggest criticism is the loose feel of the butt stock. It wiggles when fully extended. The brass gets beat up upon ejection so reloading will be difficult with this weapon. Things I really liked was the mild recoil, made possible by the gas piston system, and clean trigger pull. Overall a vey good weapon.

    I fired a brand new one a couple months ago, I put the first 300 rds through it. All I can say is a Great weapon! Light weight, I dont think I would trade my AR for it, but if I had the extra cash, I would love to own one.

    Great weapon! I've fired countless rounds and never had a problem. Folding front and rear iron sights and the best of AR/AK style weapons rolled into one. Only minus' are it is a little heavy and the plastic forearm rails. Oh and the brass hits the side of the weapon by the ejection port and leaves brass residue on it.

    i just bought this weapon. ive used the galil.223,mini-14 and ak-74..the sig 556 cycles better(after i broke it in)feels better and shoots better than any of the rifles ive used previous. the fact it takes any ar magazine is excellent as well and even with the swiss handrail for 20.00$ sig has a tri rail adaptor kit. the attach points for a one point sling are iffy with the collapsable model but with tweaking its fixable. an awesome rifle. i think i found the weapon id never sell.
