Next Level 308 Speed Brake This was requested by so many customers, so our team at Next Level Armament went to work and developed the NLX10 308 Speed Brake. Machined from stainless steel raw stock in the United States. We start by turning stainless steel blanks on a Mazak Live tooling lathe. Next we finish machine on to a New Haas VF2SS rotary for the mill operations. The compound porting on the millwork provides an awesome speed brake without blowing gas back into your face. Reduce muzzle rise and keep your target in sight. Whether you hunt or shoot long range, the NLX10 will enhance your shooting experience. Overall length: 2.5'
