I know I did respond. No, it doesn't install in the trigger assembly. The lower receiver needs to be drilled, and the part pinned in place. It acts like a trip - causing the hammer to drop when the bolt carrier closes. What you described would cause a slam fire at best, but wouldn't really work to make a rifle fire reliable in full auto. The one exception to this are open bolt guns, which use a lip on the bottom of the bolt face sort of as a timing device, instead of an auto-sear.roadkill » 24 Jun 2022, 1:12 pm » wrote: ↑ Hey dude...I took a guess at yer question about how that gadget works but never heard from you...here was my response.
Maybe it's installed in the trigger assembly to prevent it from requiring the trigger be pull every time...it rolls passed that function?
