Looking good. Too bad you cut the sight though, you could have just used the night sights for quick acquisition. But enjoy :beer
What is the 10 yard zero trick?
Replace front NS retention spring. IMI USA had them (new old stock) in stock last I checked. Can also try bending it to increase tension, but on my golani doing so just lightly broke the spring.
Second this, and for God's sake if you buy an AR mag adapter get one of the U/A original ones. They are expensive but they work. I've tried every other one I could find out there and theya re the only ones I use, and they really, really work.While not "original', the Tapco mags are excellent. The ones they make for ARs / Tavors are also some of the best polymer mags I have used & are usually priced right.
