Passed on from ArizonaShooting.com;
G.S.E. took their select fire AR-15 out for an over 1000 round torture test.
Every 300 or so rounds the gun was thrown into sandy water.
It is one continuous video showing how well it held up.
To me this is not new, but a lot of people think only AKs can deal this kind of torture and run.
I shot 2,000 rounds out of my AR over a span of a year and did not clean it. I cleaned it out and then over a span of another year I shot another 1,000 rounds. It did not jam even once.
Granted I did not toss the gun in sandy water, nor shot this in one day.
But the crud build up did not ever make the gun jam once.
The trick is ARs have too many companies making parts and sometimes some parts dont fit quite right together. This can make for a jamster.
Also there are too many people using crap aftermarket mags.
On top of this, used USGI mags are not always 100% in working condition.
The aluminum mags can damage easier than AK mags, but a correctly built AR will run all day with new USGI mags. 20 rounders work the best in my opinion.
Anyways, this might comfort some AR owners to see that the worry of getting a little sand or dust in their AR should not make it jam as long as the gun is built right in the first place parlied with use of correct magazines.
I have seen a few new made AKs with their share of problems too.
Most new gun problems are the need for breaking in. The thick finish seems to be the culprit. The guns are made right, but the bolt is slowed by the thick finish which causes jams.
A lot of people also are very upset that the M-14 was replaced by the M-16. The problem is, the M-14 is too hard for most to control effectively on full automatic. As a semi-auto they are great, but the need for automatic fire is therefore eluded.
Here is a video of the M-14 vs. M-16: http://www.youtube.com/watch?v=4weIh3Mc6kU
It also shows how the original 55 grain bullet had no problems in stopping power. It was it's ability to tumble that turned this light bullet into a heavy wound.
