howdo , i shoot mostly bullpups in competition and if you do not have a cheekpiece , it would be advisable to get one made if you intend to shoot the rifle . as if you forget to close the bolt for any reason , the blowback could damage your eye quite badly . quite easy to make and fixed on with piano hinge . comfortable too . cheers HOLLY
PS on the odd occasion i forget to close mine . the blowback lifts the cheekpiece and smacks me in the chops .
