Some of the Century Arms CETME's have been known to have some issues, but most usually can be fixed fairly easy, check www.cetmerifles.com or www.gunboards.com and scroll down to the Cetme & Fr-8 forum for some great info & help. By the way I've owned a Century Cetme for several years now (and love it) and mine ran fine right out of the box, and still does after over 10000 rds. Plus you can get the aluminum HK G-3 mags real cheap, usually less than $5.00 if you look around. Also from what I've read & heard the kits are drying up so Century won't be making them for much longer. Another Plus for the Cetme is the wide variaty of stocks and other assories you can add, most any HK G-3 stocks will fit. I like the iron sites, they are adjustable out to 400 meters, the open V (battle site) is for 100 meters and closer, although I usually use the 200 meter apature for everything 200 meters and in. I've fired mine quite a bit from 450 yards and she's definately fun and accurate from that distance, no problem hitting a 16" square metal plate from that distance.
The price didn't seem too bad, they are going up in price some now, just make sure there's some type of return policy if you buy sight unseen.
If you want the Real thing look for a MARS IMPORTED CETME, they were manufactured by Santa Barbara in Spain, that's the company that made the original select fire rifles for the military. Santa Barbara made some semi-auto sporter rifles and Mars Import Company imported them into the USA back in the 60's. If you find 1 be prpaired to pay, last 1 I saw was going for around $2500.00 and it didn't last a day.. That's the next thing on my list!!
