Does the AR15 run gas directly or does it have an op-rod? I was arguing with someone who insisted it had an op-rod, but I could've sworn that the AR15 didn't have one (not including the new HK variant).

No, the common AR-15/M-16 does not have an operating rod.

Well at least he didn't think it ran on CO,2 since it's gas operated. Or did he?

The AR uses a direct gas impingement system first deployed by the Swedes in the 1940's.

The weapon needs a clean burning powder and it needs to be kept clean. The benefit is a lighter weapon and a weapon that can be extremely accurate.

no, it doesnt need to be "kept clean",, either. The fouling needs to be kept SOFT, tho. I've seen 3000 rds of reloads put thru a CAR-15 in lessthan half an hour, and all Harry did was squirt WD-40 on it every 600 rds. Contrary to silly claims made by the ignorant, sand will choke an AK, too.

No, he's a former Air Force(?) guy, and he's also my Auto Shop Instructor. He also said the M14 and the M1 Garand were higher maintenance than the Ar15, and that most people can't hit a gallon jug at 100yds with the Garand.

Some of that just doesn't sound right to me, but I also never had to clean any of the said firearms. He also said, on the first day of class, "After today, I will lie to you." oke:

WW2 Acceptance figures for Garands and 06 ammo were a lousy 10" at 100 yds. Most, however, were and are about 2 MOA. Being able to get that sort of accuracy, especially from standing unsupported, is a very different thing. With a canned, scoped AR-15, and .22 unit, tho, from the bench, I can have any 12 year old girl hitting gallon jugs at 100m, in a very few minutes.

Gunkid, please post the sources of your statements, when you choose to make a fool of yourself. Keep in mind, gunkid has stated publicly that he has minimal knowledge in cleaning the AR/M16 system and shooting also. I have no problem at all making 3 rd 3" groups at 100 yds with my stock Garand.

Being that your friend was Air force, I would assume that he has had minimal experience with firearms, period. The Garand, the M14 and the AR/M16 series are all very easy to clean providing you have had competent training and practice.
