I've been shooting ARs for years, especially when I was in the Marine Corps Infantry but not many that are 7.62 x51mm. I'm a machine gunner by trade so I've always loved larger caliber rounds because of the stoping power and increase in distance. I'm looking to purchase a new AR that fires 7.62 x 51mm / .308 Winchester but won't break the bank. Any suggestions?

None of the AR-10 variants use common parts, so I would stay away from a 7.62x51 AR.

The best option in 7.62x51mm is probably the PTR-91, a US built version of the HK-91 (which in turn is the semi-auto version of the German Army G3 battle rifle). The parts are interchangeable with the HK (except the full-auto stuff), and the G3 magazines are plentiful and cheap ($7 or so).

It is also available for about $1,000, +/-, which is considerably less than the AR-10s, the FN FALs, the M1A1s, and so on. It's a very accurate rifle and is difficult to jam. On the down side, it is a roller-delayed direct blowback, so the brass may not be reloadable.

I personally think it is the best 7.62/.308 option out there, but I'm biased towards HK products.

PO3 Donald Murphy - The G3 (HK-91) is the base rifle for both the PSG-1 and the MSG-90. Both are sub-MOA rifles.

The MP-5 uses the same roller delayed blowback system as the HK-91. It was first used in the MG-42 (7.92mm LMG), and then the StG-45 and the Swiss StG 57. It's a great system, but it does tend to ding the brass as it ejects it (and throws it half-way across the county).

Agreed. Best 7.62 AR is a PTR91. I won't discount the fact that 7.62 ARs have come a long way, but if I want a 7.62 platform and not an M1A or bolt action I'm going with the PTR. Besides, they were in my home state of CT for a bit there before the anti-gun attitude really kicked in over the past few years (at which point they decided to leave).

I've owned an SAR-3, the version of the Heckler & koch 91 imported by Springfield Armory in the 1980s. A superb rifle. By using a heavy buffer spring and different locking piece I was able to reduce felt recoil by almost 50%.

SSG Diane R. - the angle of the locking piece has a tremendous effect on felt recoil, but you need to be careful, because it also effects the time that the bolt stays locked up.

Check out the DPMS .308s. They are reasonably priced at around $1,000. I have a DPMS Panther in 5.56 and its not a bad rifle for casual shooting. I also have an LMT MWS, and it is a fantastic rifle- but it was not cheap.

This will make you groan. Fairchild had 15% off everything guns. I had a scratch and sniff which hit the high number. They added the two discounts and I walked out with the Ruger SR-762 for $690, no tax of course, about 3 years ago. That said, there's a nice aspect to its gas piston system as I reload, hence create a variety of stuff to tinker with. Shooting is very therapeutic. So it's a matter of "features" that you think are the deal makers or breakers. In these times, the norm for not too fancy is in the $1400-1900 range. So if your bank is broke on the lower number, looks like a nonstarter. There are some new FNs out there for $1200. The M1As are in the AR range too. I'd avoid any of the Noreen product as every one I looked at had craftsmanship and design problems. BTW, the first thing you do if you get an AR/SR platform is to put a decent trigger group in it. That'll be $150-180 range. And yes, shooting a real 7.62 is more fun for me. Just like offloading my Desert Eagle 50 in favor of the 460. Much more impressive on dispersing targets over the countryside. Love it when you can taste watermelon from 50 yards away.
