One of the best modern versions of a "try stock" was conceived and created by Fred Wenig formerly head of the company bearing his name.....They are really rather interesting, they were conceived so he could provide competitive shooters (primarily Trapshooters then) a platform to better ensure a satisfactory product....

Oddly enough they were wildly popular in their "try Stock" mode as primary competition stock with the Trap crowd....Several ALL-Americans of the era used them on their regular competition guns.

A famous NJ HOF member used one and seeks to buy all he can find (they are relatively scarce as you can imagine) for use by his clinic students....

I have two of them, one in Perazzi mode, one in K80 mode.....

I would be happy to forward one on loan to your student if it it would further his educational progress....
