WildBillTX (verified owner) –
I wanted a US made trigger for my Century Arms AP5. The Zenith trigger arrived quickly, it looks nicely machined from a solid piece of steel. However there are slight differences, most notably the shape and size of the safety protrusion.
When I tried to install it, using the original trigger pin, the pin would go thru only one “ear” of the Zenith trigger. Other ear was way too tight, so clearly the two holes were different diameter. I reversed the pin but that made no difference. To make a long story short, the AP5 trigger pin is 0.197″ diameter. But the Zenith trigger requires use of a Zenith trigger pin which is 0.1955″ diameter. So you need to also buy the Zenith trigger pack axle set (item KT15 for $9.56).
Once installed the new trigger operated correctly.
