I'm a sucker for surplus or surplus "style" rifles, so I just got an L1-A1 built from an Isreali Heavy barrel kit out of layaway. The receiver is marked as Imbel and made for CAI, and the receiver and barrel appear quite new, I had the headspace checked, and it is apparantly quite tight, as neither the commercial no-go or the go would close, but I believe it was because the gunsmith was closing the bolt by hand. The cartridges chambered just fine, but there were problems with the gas system. When fully closed, the bolt wouldn't go back far enough to cock the hammer, when fully open, the spent cartridge wouldn't extract. After I cleaned and lubed the gas piston, the rifle function just fine. The recoil is lighter than what I expected, and the rifle seems accurate enough, as I was able to easily hit 4' square pieces of 2x4's at about 20 yards, the distance I was testing. The sights on the rifle are quite large. I might get a recever cover mount to make the rifle more practicle to use at distance.
