i remember several people were going to begin marketing them.  Has anyone completed a block where all i have to do is notch my sten mags?  If so where do i send the $$

I think it is following the same road as the "SHRIKE"....

I have 2 friends up north of me that are trying to figure a way to make the block a one piece, and install from the top, just need to figure out how to tie the front and rear together, because it cannot be done inside the magwell like the Colt/Uzi mag blocks.

The other idea was to make the block with the connecting material outside the bottom like the "Hy-Tech" block, but need a way to retain the block in the lower, and use the AR catch to retain/drop mags. Always an obstacle to over come.

I do not know if they decided to go for it, it was an idea they were tossing around to try to make some money on, as Mark is a machinist by day, FFL by night.

i remember kaliburz/gloftoe was going after it and so was ProfGab.  i havent heard anything in months.  I have a ton of sten mags and would like to use the colt system.  I guess i may have to settle for the ASA/OLY block
