Getting pretty excited on the next rifle to buy. Dont want to spend over $500, and am looking for something in 308. Can anybody give me feedback on the  Century Arms L1a1 sporter, G3 sporter and CETME sporter?

My advice, don't buy junk.  Sure you'll appreciate it later.  I made the mistake once, but won't do it again.  As the old saying goes "Garbage in Garbage Out".

Save up and buy a M1A, PSS or even something better.

I bought a Tec 9 and it's a piece of crap.  Also bought a Cobray, it's junk.  Cetme's are okay but parts are hard to come buy.  Century Fals are a crap shoot, you'll spend more fixing em up.

Hell for that money get a savage bolt action in 308.

Hope this helps.
