Not too long ago, I asked a similar question. I was considering the Armalite/AR-10, vs. DSA/FAL vs. SA/M1A. The Armalite was dismissed first, mostly because of cost for not just the rife, but the support accessories, and of the 3, it was the most environmentally sensitive.
I respect the heck out of the FAL, especially for what it is to the rest of the 'free world', but I decided to go with the M1A. Haven't made the time to go shoot it yet, - I'm still waiting on the SAGE stock for it. But, I field-stripped it in my LR w/o any tools, so it's pretty easy to do that. Because I decided to go with the M1A, I didn't really do much study into the exact differences between the 'imperial vs. metric' FALs, so if you decide to go that route, I'd suggest really digging for the facts on that question. I believe that the general consensus is the metric ones are the ones to own. (I'm pretty sure DSA is MFG to the metric specs)
I also respect the G3/HK design for what it is, but the ergonomics just didn't feel good in my hands, and especially didn't care for the charging handle location and function. Just my personal preference.
Eventually, like many have mentioned on this thread, I would really like to have at least one FAL in my personal collection; maybe an original one for the 'world history' factor, and a DSA for the 'go out and shoot' factor.
I found a SA/M1A Standard new-in-box for 1200. Even at that price, I think that's inflated from the current market, but it was a smokin' deal given the current market. Everything's inflated, because they CAN. I don't regret the choice, and I still have more things to decide, like optics and other accessories.
Again, I feel very comfortable I made the best choice for me, (first 7.62 NATO gun in the safe) and I look forward to getting to know my gun very well. I also look forward to the day when I can spend the $$ and add some FALs to the collection.
I know I am just new to this, and am no expert, but having recently been in your position (i perceive), feel free to PM me and I'll be happy to share with you what I found, why I did what I did, and why I did it.
44 Mag and Tulsamal, I really enjoyed your posts, thanks for sharing. With regards to the rest of the world and the FAL vs M1a, I am under the impression that the USA originally agreed to adopt the FAL, but then reneged on our agreement and went with the M1A. Political arrangements, just like cost don't always correlate to the best tool for the job. Here in America, because of capitalism, and private industry making things under contract, we actually have a vested interest in NOT adopting other designs, and/or purchasing from other countries, but rather making our own, and selling them to others.
Tulsamal: sure neither the FAL or the M1A, or even the G3 or the AR now, are not 'state of the art' designs for 2009. But, just because something is or is not 'state of the art' for the current time period, does that alone make it better? I humbly suggest that answer is 'no'. Sure, there are collectors that like the historical importance, nostalgia, etc. But, we are mostly private citizens here, and we do not have the relatively unlimited funding of a government, and as such, 'current technology' has some drawbacks: Replacement parts/accessories may not have penetrated the civilian market yet, (or at least as much) operational testing in the field may not have been as thorough, etc. I'm not saying older is better, or newer is better, just that 'state of the art' is not necessarily better. When we first went to the 'Sandbox' weren't they pulling older aircraft out of mothball to use when the 'state of the art' helo's were having trouble? (I saw a lot of pics of cobras and hueys when the apache and blackhawk were 'state of the art') If the only thing the ground troops wanted was the 7.62 Nato round, they could use the bigger AR, but no, they WANT the different mechanical function that the M1A provides. Am I saying it's better? NO!, just maybe 'better,
over there' Another non-gun example; current auto designs use independent front suspension for 4x4, but in certain applications, the 'old' straight-axle is MUCH more desirable. So, thanks to capitalism, (I thank God for it daily) we constantly have a stream of new ideas. Some turn out to be way cool, others don't. And that's OK. Unfortunately, many are put into use without complete testing, for a number of reasons.
Best wishes, and I'll try and shut up now.
