speed detents

[Eltwitcho]

what is the difference between speed detents and stock IR3 detents?? will they fit on an IR3? The cap looks smaller than IR3 detents, (the part that stays on the outside of the gun)

they will not fit on the ir3 and the ir3s will not fit on the speed

The speed and the A4 uses a different platform.
It is a piston type of detent.

I posted a pic of what the 4/Speed detents look like in a thread in the 4 section a while back. What you see from the outside on the Speed/4 is just a cap, there is a spring and a different style ball stopper in there. It works differently than the IR3 standard detents.
