English to Arabic Other Military / Defense sniper-grade weapons

Rose's device, the BOSS (ballistic optimization shooting system ), offers micrometer like adjustments with 10 settings on each of 10 rotations_100 distict barrel lengths to fine-tune harmonics.In essence , this is the opposite of what a handloader does: instead of tuning the load to the rifle , you're tuning the rifle barrel to the load..I tested the BOSS extensively and found that it worked superbly-yet it hasn't taken off like I thought it would.
