Proline Auto Response frames?

[Mag-Convert]

I used to have a couple proline auto response frames when I first got into mags a few years ago, but sold them before knowing what made them so cool. I recently got another one in a lot and have a couple questions about them.
First off, does anyone have an idea how many were made? mine has a serial of 3010, but I don't know when they started the serial number.
Also, I've heard that short stroking them is a possibility, was wondering if an hsi reactor on/off would help decrease this compared to the stock on/off in a classic valve?

Thanks

I don't know if any records were ever made from proline. Plus it being a nearly 20 years ago, any records could be lost forever.

No experience with the reactor on/off, but a RT on/off might be a better and easier option. But with any and every mag, as line as you practice proper trigger hygiene, the short strokes should be kept to a minimum. Also a L10 kit would also helpif or when you have a short stroke that it won't chop.
