In general, long rifles do not look good in blockland, as, logically it would require two hands to be held. However, blockheads should not stretch their arm to 3x it's original length to hold the end of the gun. Also, rifles are not well gripped by Blockheads, because their hands are vertical, but the part of the rifle you are supposed to hold is diagonal. So, that's why this hasn't been made, and why it likely will never be made.
