i think if he sends it to martin they might replace limbs free, i dont know, but i know a guy who had his limbs blow up on a martin 2 weeks before season a couple years ago he sent it to them and had it back within 1 1/2 weeks and had it retuned and sighted in by the opener, his wasnt caused by a dry fire but they did replace the limbs free, they may do the same for your bro
