My apologies on getting the designation wrong. It is marked Centurion 58. Was getting it mixed up with another. Oops, I am human.
I had one of those. It's not a SA58 just a Century S.H.I.T 98! Mine had a hacked metric Imbel receiver capable of taking inch mags and the rest was Indian/Australian and a little bit of BritFALs and all their variations can be so hit and miss. Many times one that looks horrible can easily be turned into a great shooter.
I bought an Imbel receiver SA-58 made by Century. Not only were there no part numbers that matched, but I had to be careful buying replacement parts as it was a nice mix of inch and metric. The receiver was an inch pattern, which when I bought it wasn't a problem. As to the part numbers not matching, I went over the rifle carefully and found the Century two piece op-rod was not straight, which could explain why I got it for a great price. A call to Tapco back in the days when they sold to the public purchased a one piece rod and a couple of other parts and I wound up with a very reliable and super accurate shooter. I have no problem holding a 4 inch group at 100 yards using the iron sights, while standing! I can't imagine how accurate it would shoot with younger eyes!
I write the above to let you know that diamonds in the rough are out there. Learn as much as you can so you can tell whether an all numbers matching is really a good buy, or one like mine with no numbers matching but a tiny bit of work to make it a great buy! Your question here is a great start.
Some of the last good rifles that DSA came out with a few years back had NOS inch bolts. FWIW, the bush carbine ARS built for me had one as well.SA58 is a DSA designation and are all metric. You won't fine a DSA SA58 with L1A1 parts. You won't find a DSA SA58 with an IMBEL receiver. You won't find a DSA SA58 made by Century. You won't find a DSA SA58 on an "inch pattern" IMBEL receiver. I think you may be confused.
Two piece pistons were junk, Tapco did sell a one piece stainless unit that was good to go and found their way into many a home build.
It was actually my wife's idea to buy a 308. I've been slowly acquiring 7.62 over the years and came across another few hundred rounds last week. I suppose it makes sense to get something that will eat it.If you can, try and find a FAL for sale that is built by someone who knows his way around them, and they do come up for sale all the time. The only thing I'll add is get some mags NOW, and make damn sure you can feed the thing ammo, because now is not the time to try and stock 7.62x51. FALs are great rifles when you have one built out of quality parts by a builder who knows what he's doing.
Seriously, I would try and look for one built right that's for sale. By the time you get a kit, receiver, and 922 parts, your going to be close in price anyway. Buy mags now....It was actually my wife's idea to buy a 308. I've been slowly acquiring 7.62 over the years and came across another few hundred rounds last week.

Best place for a good kit build? FALFiles? GunBroker? $1500 is probably top of the budgetSeriously, I would try and look for one built right that's for sale. By the time you get a kit, receiver, and 922 parts, your going to be close in price anyway. Buy mags now....
