The RT Pro Sear is the sear of choice. Because it is a fixed position sear, it doesnt move vertically in the rail.
At high rates of fire, this is preferable. This is why the fixed position sear is used in the E-mag(the E-mag has an additional arm for use with the solenoid/plunger).
The finishing and hardening process of the RT Pro Sear makes it more costly to manufacture. As I recall, it goes through 3-4 different process before it becomes a final product. It also uses a brass bushing, which must be pressed into the sear.
Occasionally, a pressed bushing can cause stress fractures in the sear pivot. This causes a double-fire for every pull, and the only solution is to replace the sear.
Sometime in late 2006 just for °°°°s & giggles I pressed out a few of the bushings and replaced them with bearings. Not really a new idea, as the older AGD Classic RT sears have roller pin bearings.
To use them in this configuration requires spacers though. The bushing was manufactured with a width that limits the side-to-side travel. The bearing isnt wide enough to do this.
All the sears in the pic are RT Pro sears. The two top sears are a standard AGD RT Pro sear profiled from the left and right side. The bottom left sear is a standard AGD RT Pro sear with the bushing removed. The sear on the bottom right is the AGD RT Pro sear with the bearing I installed.
And for the pic...
