I'm guessin to Shartley's question.. I'm taking since he's a stock user, less on the right side to eliminate the possibilty of catching the stock on the 12grams when he shoulders? and/or to keep them out of the way when cock's his head to the right to aim from catching his mask? Just a guess anyway.
