Mudstud has it right on all the negatives except for the brass

First off, real H&K 91�s do score up the brass, but it is reloadable. The PTR�s use much shallower fluting of the chambers, which does very little scoring of the brass; again, it�s completely reloadable.

The real down side of the AR-10 is that it�s not a real military rifle. It�s based on a military design, but it�s not built to any military spec because none exists. The real AR-10�s that did see military service were poor performers and most were phased out within a few years of adoption.

Splattermatic has it correct. Of the .308 battle rifles, the FAL is the clear winner. It was adopted by most of the free world and has won out in most every military test it has ever been put in. The Germans only adopted the G3 over the FAL because of licensing issues, not because of performance. The US had to re-design the US military rifle tests a few times in order for the M14 to come out ahead of the FAL.

There�s a reason the entire free world adopted the FAL; it works. Out of the box, a FAL is more accurate than a G3 or M14 and the original AR10�s. These days, a good FAL is every bit as accurate as a standard grade M1A, more reliable, parts are much cheaper and more readily available, so are magazines. The DPMS AR10 is a proprietary design for many of the parts, so if you have parts breakage, you have to depend on DPMS being in business and continuing to make that model forever.

Parts availability for the PTR is much the same as the FAL, cheap and available.

It all depends on what you�re looking for. If you�re looking for a battle rifle, then the PTR is clearly the better choice over the DPMS AR-10. The G3 design, warts and all, is a very proven design and it works. I don�t care for it much, but it really does work.

Still, I think the FAL is the best of the .308�s hands down; again, talking about true fighting guns.

If you�re looking for a range toy, then the DPMS is the clear winner, because it will make smaller groups, easier to mount optics on, and the triggers are better.

Problem with American shooters is, they will always opt for more accuracy over more reliability; which is why the AR and M1A�s reign supreme in the US.
