the cetme or g3 from century is more or less a crap shoot. they may have gotten better at it by now. for 300 a 308 plinker aint bad. if you want something that shoots better got for a fal. cost more, but is more accurate. replacement parts are very common on both. the cetmes design has some wearable areas like the cocking mech. you pull it back when cocking. the side ways pressure makes the part wear uneven. when it is worn bad you will not be able to easily cock the gun. 10 dollar part, but all the same. fal has adjustable gas system. great for shooting hunting and/or mil surplus. you can adjust how much gas to release. you should adjust it so that there is just enough to cycle the gun with the ammo that you are using. i have both. the fal is sweet by all means. for the price, i would get a remmy 700. and then eventually upgrade the barrel and trigger to make a serious tack driver.
