SLR15 Rifle Specs - Carry Handle
Left side knobs is the industry standard. The SLR15 Rifle also has right side knobs, so the knobs do not interfere with a right handed shooter during manual cycling of the charging handle.
A right handed shooter will use their left hand to manually cycle the charging handle; if the knobs are on the left side, the operator scrapes their left hand against the knobs. We put the knobs on the right side so they will not interfere with the left hand.
