2 gun where are you in MO? Have you actually shot a CETME or a FAL? If you're close to me I could arrange some shooting time, or come out to the next MODCC shoot in Columbia and we'll have main battle rifles for you to play with there.
Its best to try something out firsthand before you buy, don't you think?
Also, a few details:
1. No semi-auto .308 in your price range will ever be sub-MOA. There are $1800 Armalite AR10Ts out there that are not sub-MOA out the box, they must be tuned and ammunition must be loaded specifically for each gun to achieve that performance level. What ammunition were you planning on using for your sub-MOA battle rifle? Hope you weren't thinking of using military surplus or you're in for a big surprise. In any case, if you can get sub-inch groups at 100 yards with iron sights on any of your rifles, at any price, I could use some instruction from you on how to shoot accurately when we meet!
2. Hand select is always worth the money. You're spending hundreds of dollars on a gun and probably at least $25 on shipping, why not pay another $10 to have them pick out a decent one off the rack for you? Always get the best condition gun offered, every time, especially in this price range.
3. Clips are what feed an M1 Garand. Stripper clips are what feed Enfields and Mausers. AR15s, CETMES, and AR10s feed from magazines. Only inner city gangstas and white trash with plastic-stocked SKS's are allowed to say "clips" when they mean "magazines", and I'm sure you're neither one of those people!
4. BARRELS: Even if there were a source for longer, more accurate barrels, installing one would cost more than the rifle is worth. In a G3/CETME style gun, you would have to remove the barrel and trunion assembly (kinda a bitch since its welded in there), press the new barrel onto a new trunion (got a 12-ton press handy?), and reweld the trunion back inside the receiver, and maintain perfect barrel-to-reciever alignment the whole time. You wouldn't want to shoot 5 yards to the right at 100 yards like my G3 clone did when I first got it, yes I made Century do what I just described under warranty and it took them over 3 months to get the gun back to me.
Also, did you consider how much extra weight a longer barrel would add? These main battle rifles are heavy guns to begin with, and many a shooter who thinks he's a "real man" can't hold the rifle steady for a full 20 round mag. They get impatient because their arms get tired, so they wind up dumping off the last 7 or 8 rounds rambo style or switching to shooting from a rest. The G3/CETME weighs in at about 9.7 pounds, and my FAL tips the scales at about 11 pounds with the bipod. Again, I'll be glad to let you shoot my stuff sometime.
Email or IM me if you have any further questions. I also used to own a Savage 10FP, they are good for the money but also need a little attention to detail (and careful handloading) to bring out their full potential. Order from Aimsurplus with confidence in any case.
