I got a Century G3 recently, and it's been an accurate, reliable piece of machinery. Everyone says I was lucky, supposedly 1/3 don't work properly, but I'm more than happy with mine. The only problems I've had were due to some crappy surplus ammo that didn't fire. The primers were dented deep enough, they just didn't work.
My G3 is currently at
Arizona Expert Arms, getting a face lift. It's already got a wide Springfield forend and an HK carry handle, now it's getting the Century brake replaced with an ARS fake flash hider, getting a paddle mag release installed, and getting reparked and refinished in HK Satin Black. I'm working on getting a replacement grip with the same profile as the plastic Navy lower, then it'll be done.
The 20rd aluminum mags are $3.00 each, and Portugese ammo is $135/1000, how can you beat that??
