Superlative Arms Gas piston system. We have tested several other gas piston systems and have settled on the Superlative Arms for dependability and ease of cleaning and adjustment. Has positions for full piston charge, reduced piston charge for suppressors and no piston charge for single shot firing. The Fortis Switch MLOK Handguard is extremely comfortable and has a latch system to easily remove handguard for cleaning the piston system.
