Listing for 20 x 102mm Dummy M51A4N (AA20) by Mast Technology

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?

PGU-40/B dummy from Mast Technology, covered in an earlier thread:

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,
