[Bug] Left hand wrongly placed in first-person perspective when Beyond Earth space suit is worn

[chemlzh]

I have found that when I wear space suit from Beyond Earth mod, the left hand is not placed under the handguard, but at the right side of the gun (Fig. 1). Wearing other chestplate (such as TerraFirmaCraft steel chestplate, see Fig. 2) or take off space suit (Fig. 3) doesn't have this weird gesture.
