This knob fit my CA-3 G3 clone built from surplus FMP parts perfectly. The flat oval washer on my sight was a little bent, but I flattened it out with a hammer. Now it all works as intended. I had to have this upgrade part, and I want to make a few more upgrades as soon as I can.
Awesome product. Makes adjusting for windage a snap.
Just installed this on my Century Arms CA3 rifle (aka HK/FMP G3) today....then I see this in my inbox....Wow, great timing...LOL. Anyway, I'm highly impressed with the product. Makes adjustments to windage much easier, without having to search in your range bag for a Phillips head screwdriver. Easy install, only took a minute. Quality was great, can't tell any distinction/difference in color of rear sight and base from this adjustment knob, made of metal, believed to be steel. Function was perfect. Price I thought was very affordable and competitive at HKP. I highly recommend this upgrade. .
It took me a second to figure out how to install, but once i did, it was a breeze. Windage adjustments are much easier, it's built solid, the finish appears quite durable, and it looks good. Very satisfied!
great thanks
