Below I have a couple of videos that will help you install the parts into your ACE fcu and then place the ACE into my grips. If you have any questions, please let me know!

First, you will need an area of your house that will make it easy to find small springs and pins that drop, trust me you will drop them!

Then you need a glock punch or similar sized punch, 3/32 is ideal.

Follow the videos, pausing as needed, and keep the little parts baggie to place your ace parts into.

How to install my parts

The Glock backstraps are very, very tight; the method demoed in the video is really the only way to install them. Don't forget to cut down OEM Gen 5 backstraps to clear the fcu!

An important thing to note is that the springs can get bound up and crooked and will create a clicky, odd feeling trigger. If that happens, just make sure the springs are completely straight, and you should be good to go.

How to install the TLR1 

• Insert the light fully onto the rail and push hard to make sure it's all the way to the rear. It's not designed to be used in other rail slot positions.
• Select the correct locking bar with your model written on it
• The lettering marks the front (Except CZ is written on the back) 
• Press the locking bar in from right to left, inserting the end with the screw head in first. It is tapered slightly and can be damaged when installing it the other way.
  
• It may take some light taps with a rubber hammer, but it's designed to be doable with the hand alone, so just be careful and make sure it's aligned correctly to avoid breakage.
• If you need to remove it, use a punch and punch on the screw head end.
• If its not as tight as you like, superglue works well to stop it from wiggling.
