These are the tools that I used to install the Apex Ultimate Striker Block:
First of all, loosen the set screw on the rear sight:
I placed a piece of duct tape on the end of a piece of 3" long aluminum stock. I did not have a brass drift punch, so I found a 4' long rod at H.D. for about $4.
I lightly drifted the sight to the side (it only goes one way!), and once I got it about half way, I used the provided plastic tool to push it the rest of the way off.
As can be seen here, there is a small disc that holds the striker block's spring in place. Be careful with this guy, because it will want to launch and fly off.
The Talon tool provided works perfect to remove the sight and keep that disc in place. Here I slowly removed the Talon tool, and held the disc in place with my finger, then let up on it, removing the disc and the spring.
From there, you can simply remove the striker safety plunger. Here is a picture showing the difference between the original and the new Apex one. As you can see, the Apex SB is polished and more rounded off than the stock one.
Installing this totally got rid of the 'grittiness' of the trigger pull. This was by far the easiest part of the DCAEK to replace. This, along with Apex's RAM, makes the trigger feel soooo much better. Almost like it should have been to start with
- Small hammer
- 1/16" Allen wrench
- Aluminum round stock
- Vise with padded grip inserts
- Apex USB parts
