Contract listing for 20 x 102mm Dummy M51A4N (AA20) by Mast Technology. The M51A4N has a metal head and the remainder of the dummy is plastic.

Has anyone seen one?

Hi Brian,

This round was standardized in 1998 and early production was carried on in Israel by Plastokit. Below you can see a picture of the current improved version made by Mast.

Head/stem is made of stainless steel and body is made of fiberglass reinforced Nylon (stem is pre-heated before insertion into the mold). It seems that Mast subcontracts it production with RTP Co. of Winona, MN, who also manufactures their 40mm plastic cases.

Regards,

Fede
