Early AR-10 Reliability?

[BushmasterFanBoy]

In order to keep another thread from going off track, I've decided to ask this here.

Along the course of development for various AR-type rifles in 7.62, inevitably, reliability is a big concern. This seems to be almost counter-intuitive, as Stoner originally designed the rifle in 7.62mm, and as many astute gun-fanciers know, the "original" is oftentimes the most trouble free design, since it has not been adapted or modified in unintended ways.

This seems to beg the question, how reliable were the old AR-10 prototypes? I've seen videos of test firing, and while they're quite impressive, they are sales/marketing videos, and not impartial tests. I'm just curious if 7.62 ever really worked in the AR, or if only the modern iterations of it encounter decreased reliability when compared to the very thoroughly tested 5.56.

IIRC, the AR10 placed second behind the FAL in the South African trials of 1960. Not too shabby for a
weapon with a LOT less time in development. I suspect the original AR10 was at least as good as any
version we can get today.

As reliable as a G3. Portugal used both in Angola.

The only modern AR-10 I've ever heard of working well has been the LMT 308. It's heavy (10lbs), but it beat the HK 417 and 308 SCAR in the British DMR trails and those are two seriously reliable rifles. Having used both, I wouldn't trust a DPMS or Armalite AR10 variation for any serious use.

A modern Sudanese model AR10 with a flat top receiver would be a beautiful thing.

Portugal was the big end user in combat, in both Angola and Mozambique. They actually issued FN FAL's, HK G3's, and Dutch production AR-10's side by side in theatre. From what I've read and heard, many Portuguese troopers preferred the AR-10 for it's weight and were very happy with it's reliability.

Chuck Taylor wrote several articles about the AR-10 back in the 1980's, using several original select fire examples for his articles. It was his favorite battle rifle.

Besides Portugal, Sudan, Nicaragua, Burma, and several others bought Dutch production AR-10's.

The "new" Armalite AR-10B's are cosmetic clones of the Sudanese version.

I'd love to have one of the semi auto builds using military surplus AR-10 uppers and one of the commercial lowers that came out in the early 80's, but they start at around $3K.

The best AR rifles ever made were the Dutch AR-10s.

KAC SR-25 It is after all a Stoner Rifle.

Would be nice if Armalite made a reproduction that was identical to the original. No heavy barrel's, no heavy BCG's. Not the bastardized AR10B they produce with they're non compatible magazine.

Tagging for interest

Hmm. I was in a gun shop today and spotted what I thought was an AR-10. Not knowing much about them, I noted the brown furniture, the carry handle charging handle, and a six digit serial beginning with "5." The proprietor intimated, but did not outright say, that it was a 1960s-era AR-10.

Where can I find out more about these rifles to asertain when this model was made?
