Sig 556 S.W.A.T. 5.56mm

When I first caught wind of the SIG556 project almost three years ago, I looked forward to getting my hands on one, so I put in an order with SIG SAUER. Like with many new firearms, the production date was repeatedly pushed back. Then, about a year later, the ultimate teaser; I had the opportunity to fire a prototype 556 version including a fixed side-folding stock with select-fire capabilities. This only served to heighten my anticipation—the weapon was comfortable to shoot, accurate, light recoiling, and reliable. It was also very controllable in full-auto mode. The gun also looked very slick; the fit and finish were excellent. My initial experience with the 556 left me with a feeling that I liked it possibly more than the familiar AR15 pattern guns.

sig21.gifThe SIG550, forerunner of the SIG556, has its roots in the SIG SG-541 or Stgw.90, which was officially adopted by the Swiss Army in 1983. The SIG550 has been called “the finest 5.56mm rifle ever made” by some. Restricted for years to military and law enforcement (LE), the 551 (carbine version) was actually one of the few weapons to be selected by the feds for their agencies along with the RRA DEA carbine. The guns that won the contract were among the last standing of a brutal series of tests, and earned a reputation for ruggedness and performance.

Today, SIG SAUER has brought the design to the shooting public and law enforcement in the United States in the form of the 556, basically a redesigned 551/552.

    I just got the classic Sig556 classic and really like it had a little trouble get my iron sights just right I’ve been see a lot of bad hype about the Sig 556 on the net. I never own any type of Ar so I don’t know which is better than the other I like the way the Sig look and felt in my hands it is a little heavier than the other AR type rifles, is this a good or bad thing I don’t know but what I keep reading is how the Sig brakes doing this or that so far it fired everything I put in it. I just need it to be reliable when the time comes the price was a little high,for it not to be a good rifle so I don’t know but if anyone else have the Sig 556 tell me what you think. Has it held up for you have you had problems E-mail let me know if I should keep it or trade it for something else

    Fred– I have a copy of almost all of the SIG models.The only real small model is the P232 in .380. It is light,very accurate out to 15yds+, but is ltd. to 7+1 rds.I wish SIG would develop a double stack magazine for one in that size.
    The new multi-cal. polymer P250 is a little smaller than your P226. The P229 is a little smaller but not substantially. The P239 is avail in 3 cal.,mine came in .40S&W and I later bought the .357SIG bbl..Again, its limited in magazine capacity.
    Good bet– find a compact model you can live with,put a lazer grip on it,geta 20 rd.mag for the nightstand.You can add the light to the rail if you like(Surefire)or get a good Surefire handheld.20 rd mags can be had for 9mm,.357SIG,and .40cal.They are good for nightstands AND the door pocket of cars/trucks. Good hunting.If you want something REALLY small you need to look for slightly less quality–the trigger pulls will suffer.

    I just got my sig 556 swat addition rifle, and have not yet had the opportunity to fire it. However the pin that allows you to field strip the gun slides out very easily ( almost makes me uncomfortable). Is this normal?, In addition, i am on the fence about optics, narrowed it down to two diferent peices, eotch or trijicon.

  • As a proud member of the Swiss Armed Forces I’d like to add that not the SIG 541 is called the Sturmgewehr 90, but the SIG 550. It was adopted by the Swiss Army in 1990 (that’s why it’s called ‘Stgw 90’).

    I am looking for a smaller defensive weapon for my own personal protection. Light wieght with minimum amount of recoil that is easily concealed.
    I own a Sig 226 9mm and I love it but it does not meet this critia. I did own a Walther TPH 22. but that did not have enough to do the job and was not reliable.
    I have read about some hand guns that are that are polymers. I have also read about the FN five seven but that is too large. I could use someones knowledge and opinion, that knows great deal more than I.
    So if you have any recmmendation I would appreciate your in-put. Choices of Manufactures and Calibers.

    Thank you, in advance for your help.
