Sig 556 Swat Patrol

I had several 556 rifles, years ago. Sadly, SIG discontinued them and essentially abandoned them. Even when they were in production, no parts were available except for maybe a recoil spring. Aftermarket support was very limited. I sold the ones I had.

If you decide to sell, yours will generate some interest because of the Swiss stock and the lower. The quad rail and short gas system are drawbacks. They are decent shooters, but many better options exist out there. Like an AR-15.
