The P556 takes advantage of SIG Sauer's renowned SG 550 .
The omission of the buffer tube grants the immediate advantage of utilizing a folding stock, allowing for reduced rifle length during transportation or close-quarters engagements. While the original 550/551 line used proprietary magazines, SIG Sauer adapted the 556 model for the U.S. market, enabling compatibility with standard STANAG magazines found in most AR-15 rifles.
The long-stroke piston design offers two notable improvements over the AR-15. Firstly, the piston-operated system keeps the internal components cleaner by utilizing a piston to reset the bolt instead of direct impingement gas, making maintenance a more manageable task. While the debate on how much this directly impacts reliability continues, there's no denying that it contributes to overall cleanliness, enhancing longevity, and ease of maintenance for the P556.
The price of Sig Sauer 556 is quite high but may vary depending on various factors. In 2023, the best price of the Sig Sauer 556 for sale exceeds 2 thousand dollars, but you can buy a cheap Sig Sauer 556 if you plan to use a weapon from the previous owner.
