I went through this same decision 5 months ago. The fever was Red-hot back in January, and I had caught it. I was considering an Armalite AR-10, a Rock River AR-10, a DSA-FAL, and an Springfield M1A. I decided on those brands for quality. I didn't want to risk buying junk. At one point, I had basically decided to purchase the first one I could find in the configuration I wanted. Dangerous decision. Then, all in one day, I found an Armalite AR-10, a DSA-FAL and an M1A.
If all other things are equal, (and they NEVER are, there is always a variable), the AR design may be the most accurate. However, plenty of folks have competed in 1000 yd matches with an M1A, and been competitive, so in my humble opinion, it's mostly the user. (for my tastes, if I NEEDED that much accuracy, my plan was the bolt gun and monster scope.)
During my search, I was told the FAL had been dubbed 'the right arm of the free world'. Many countries used the FAL as the Main Battle Rifle (.308 caliber). So, that being said, the rest of the world was using FALs, while USA was using the M1A. (I had been told that originally the USA had committed to going with the FAL, but re-nigged on the agreement for political reasons, can someone confirm this?)
I did decide that if I was going to go with the FAL, it would be one built to the Metric standards, not imperial (inch). I liked the adjustable gas valve, and one of my 'musts' was a collapsing stock. At least some parts are not interchangeable between the two, should you decide to go that way.
Sure, the AR design guns are all over, made by many, and have lots of interchangeable parts. And while I have zero facts to back this up, it's my hunch (and it's my money, so I'm entitled to my hunch) that the FAL and M1A would require less parts over the long haul. Anyone else confirm or deny this?
It also seemed to me that the M1A was able to be worked on and serviced by a lay-person with a good book, decent tools and a general mechanical knowledge. (I am blessed to have all three, others may not.) The FAL seemed to require more specialized tools and specific smithy training.
One thing I liked about the Rock River product, is that they are supposed to use the FAL mags, and that's worth considering. The Armalite mags were going for upwards of $80 each, and I have been told they are propitiatory. FAL mags were the least $$ of any of them - but you had to make sure to get the correct ones (imperial vs. Metric).
On that magical day (03Feb09), I followed my gut, and went with the M1A. I got a brand new, Springfield M1A standard for 1200.00, ordered the SAGE EBR stock, and waited for UPS. With very common tools you can buy from Home Depot, you can totally disassemble your M1A, and re-assemble it. (Can't do that with the FAL) Field stripping it requires no tools, they have a great reputation in unfavorable conditions, (so does the FAL, but not the AR), the design is plenty accurate
Here's a quote I lifted from my post in the thread I started about this decision:
In summary, from all the replies here and other readings, this is what I came up with: And keep in mind, this is WITHOUT Gunsmiths-type work --- out of the box with simple mods, (stock, accessories, that kind of thing)
Out of the box accuracy:
1st place) AR style 2nd place) M1A 3rd place) FAL
'environmental resistance'
1) FAL 2) M1A 3) AR
Easy to work on for lay-person
1) AR 2)M1A 3) FAL
Mag avail: (and this is debatable with the imperial vs. metric issue)
1) FAL 2) M1a 3) AR
Avail of parts in USA
1) AR 2) M1A 3) FAL
* again, debatable because of proprietary components in certain AR platforms.
While the M1A appears to be 2nd place in just about every category, with what I could find, in each category, While the M1A was in second, it was a very close second, and good arguments could be made why it should have been equal to #1.
Some would argue that the M1A is a marvelous concept, not just a great gun. (all of the ones mentioned are great, IMHO) The idea that every part on the M1A's original design does at least two jobs, sometimes more. Very few moving parts, and it does the job so well. Don't get me wrong, I LOVE the FAL. I still very much want a couple: a DSA-Para model to shoot, and an original for historical interests. But on my current budget, I had to start with one.
So, all told, I'm into my M1A about $2500.00 (don't tell my wife
) I have the action, the stock, and 20 20-round mags. I don't have optics yet, but I am more concerned with guns that are likely to be restricted right now, so, and with the great iron sights, the need is not as great.
So, that's the direction I went. I'm very happy I did.
