Find me a nylon 66 that has even a decent trigger and can hold zero between outings with a scope on those grooves in the separate receiver and I'll like it alot more. For me, i got rid of my nylon 66 and prefer semis like the 10/22, mossberg 151 and even the norinco jw20. Each of these has a far better trigger and can be scoped so that they hold zero. The nylon excells as an open sighted trunk gun, its a very light, super durable almost never jamming gun. As long as you can live with its short comings no doubt you'll like it. But it's not a perfect design.
My deal breaker was slowly working that creeping trigger while trying to shoot shotgun shells off hand at 25 yards. Talk about frustrating and exhausting. And having to resite the scope each time before I shot it. Oh, and having to be careful how i held the stock so the point of impact wouldn't change between shots. Once i tried a Brno model 2 the nylon got the boot with no regrets. When i miss a shot, i prefer it to be my fault.
