No1Mk111 Receiver Holding Fixture

[bigduke6]

Tom, the only thing that springs to my mind is a mandril with tapped holes to pull it down with screws which go through a plate the screws being vertical and passing though the mag well area, the plate also incorporating a clamp ( similar to an action wrench) at one end which the bottom half is permanently attached to the plate and the top half screwed down to this, also at the other end of the plate having something similar to the draws on a fore-end....

I,ll try and get a drawing up next few days, but if you think of a short Steel type of fore-end, a clamp at the breeching up ring, a mandril fitting through the bolt way and being pulled down with decent screws vertical though the mag well area could extend the mandrill and pull down at the rear also.
