Evan “Goon” Neale posted asking about the correct sear to a Proline Autoresponse frame so I pulled out this trigger, sear and linkage to photograph.
This photo shows the trigger, sear and linkage piece.
Evan asked what radius the circular cutout on the sear had. A nickel fit almost perfectly in the cutout. The Auto Response Trigger, Sear and linkage on the left compared to a classic Automag sear on the right.
The Auto Response Sear and linkage laying on top of the Automag sear. The sear is almost identical with the exception of the cut out and the rounded bottom of the sear where the linkage pivots on the Auto Response sear. The classic automag sear has a square base.
The base of the two sears compared. The Auto Response Sear, Trigger and linkage (front) has a rounded bottom.
From what I’ve seen the Auto response frames are identical to the standard proline / Gun FX Automag trigger frames. Both early frames typically have the hole cut out of the base for the spring that hooks into the link to attach and only the trigger, sear and linkage are different. I know my Team Sasquatch Micromag seen in the video below has the same hole to hook the linkage onto. I actually plan on inserting the linkage photographed into the Team Sasquatch mag’s frame.
Thanks to Goon for prompting me to take these photos.
