The Spike's Tactical Compressor is the long awaited culmination of SBR and suppressor technology. Developed in conjunction with active law enforcement, the ST Compressor has been brutally overbuilt without losing the finer points that make it Sub MOA accurate at extended ranges. The ST Compressor is the first factory produced SBR with an integrated sound suppressor that requires no maintenance. By employing billet technology, its designers were able to cleanly design-in every feature that was previously applied as an external add on. With the use of self lubricating coatings, and heat-sync technology, the ST Compressor represents the digital upgrading of the analog rifle.
