Rare original SSK Industries 16” Stainless .300 Whisper complete upper, built on an A2 receiver with fixed front sight. Two port compensated barrel is threaded for 5/8x24 over the barrel suppressor manufactured by SSK. Factory test fired only.

The SSK adjustable gas system solves the problems of functioning with a quite wide window of proper functioning, with a wide range of powders and bullet weights. This system has an L—for generally low velocity ammo and H for high velocity ammo, and in-between those settings the gas is shut off.
