The trigger is too far ahead of the grip; unless the person using this weapon has a really long middle finger they will likely be unable to function the weapon. The scope mount is very wonky and would likely snap off or become at least misaligned by actually firing the weapon. The hand guard with the way you've mounted it on the weapon there will direct all the heat down onto the users hand, possibly burning them. The where the bipod is mounted would actually degrade accuracy severely and the mount you have on there would be very poor and most likely be prone to breakage from firing the weapon.
