4.0 Rating Fits - 10/29/2010
Reviewer: ZM
This was installed on a Del Ton DTI-15. I followed the directions on the cardboard insert and the tips found in these CTD reviews. I worked it in and out of the hole from the other side 2-3 times, then tried putting it in. I repeated working it in and out the other hole until it would fit through the proper side. It helps if you have a flashlight shining in through the back of the carrier group so you can be sure the pin is actually lined up with the right side hole.

4.0 Rating installation - 9/21/2011
Reviewer: kam
I bought a couple of these after seeing all the problems people have had with them breaking. Once I had them, I ooked carefully at them and the bolt carrier, so long as you turn it so that the gap is vertical, checked by veiwing it in the light, it goes into place without any issues. I have used it and cleaned my gun half a dozen times and it is still going strong. One issue is removing it since it locks into place almost impossible to do without a tool. A bobby pin or spare firing pin works excellent.

5.0 Rating Bout Time - 2/10/2009
Reviewer: Andy
Bout time someone went back to the original "Stoner" style of retainer. Fit the pin pocket of the carrier perfectly relieving that concern of mine. Instructions are clear and concise. If you break it during installation, well, you just didn't do it correctly.
