How did I know that magazines were going to be the first comment I received. My magazines:
1 - 30rd Thermold
1 - C Products Aluminum 30 rd
2 - C Products SS 10 rd
3 - El cheapo Sportsman's Guide steel 10-20 rd (I've all but thrown these out)
They all do the exact same thing in my rifle, regardless of how they are loaded. All but the 3 cheapos work fine in dad's AR-15, and they work better in his than they do in mine. I've also tried a couple of dad's mags (can't recall brands) with the same results.
1) I hear you about breaking it in but I've already shot a couple hundred rounds through it, and the amount that it happens is unacceptable even for a new rifle. Comparing it to dad's again but his never did this straight out of the box.
2) I've tried about 4 different brands of ammo with the same results. Dad's shot my worst ammo and it worked fine.
3-4) I've checked these out once, but I'll certainly look again
5-6) I partially suspect this. After purchasing I had the original sight style gas block replaced with a low profile version to use with a scope (flattop upper). I had this problem before the block was replaced, but that doesn't mean it was lined up right from the factory. It is the 16" barrell, just not colt.
7) I also suspect this, but not sure how to check that it is the right one. As mentioned above it's 16" barrel and had fixed stock.
8) Ordered a JARD adjustable single stage last Friday. So if that's an issue not, it shouldn't be for long.
9) Will check it as soon as I have a chance.
10) Seems to be good there. I'll double check on the magazine, but I'm 99% certain it's good.
First thing we need to do is determine if it is short stroking or if it is a failure to feed.
Failure to feed is a magazine issue.
Short stroking is a gas issue.
Once we determine what the issue is we can start working toward the solution.
Short stroking (Failure to cycle)
Short stroking on an AR rifle is when the bolt carrier group does not cycle far enough to the rear to be able to strip a round from the magazine and chamber the next round. After firing a round, you will notice that the bolt is closed on an empty chamber, thereby forcing you to manually cycle the rifle to feed the next round. This occurs when there is an issue with the gas system.
To see if you have a short stroking problem and not a “Failure to Feed” problem, please perform this test first (assuming your bolt catch and magazine is functioning properly). Insert one round into a magazine that you know to be performing well. Insert the magazine into the magazine well, pull the charging handle to the rear, then release the charging to load the round into the chamber. Safely discharge that round. After the round has been fired the bolt should automatically be locked to the rear by the bolt catch and the empty magazine. If the bolt is closed on the empty chamber, then it did not travel far enough to the rear to be held by the bolt catch, and your rifle has short stroked.
Short stroking is a symptom of a problem with the gas system in the rifle. There are 7 parts of the AR gas system. In the upper receiver group, you have the barrel (gas port), front sight base, and gas tube. In the bolt carrier group you have the gas key, the carrier, the bolt, and the gas rings.
Assuming the rifle was running correctly previously (in the exact configuration it is currently) The following is a basic trouble-shooting checklist.
1) Ammo issue ? Commercial ammo does not run as hot as Milspec ammo, and some lots of commercial ammo may not be strong enough to cycle the weapon. Try a completely different type of ammo. If the weapon works correctly then you may have some bad ammo. This is becoming a more common problem with some of the low cost imported ammo, especially with milspec sized gas ports.
2) Lube and clean the rifle. Pull out your GI manual and properly clean the weapon. As a note, a little bit of dirt and carbon should not stop the proper cycling of your rifle.
3) Check the carrier (gas) key. If the carrier key is loose, the gas system will not hold enough pressure to fully cycle the weapon. Try a different carrier that you know to be working in another properly functioning weapon. If the weapon runs well with the other carrier, you may have an issue with your carrier key. The carrier key bolts should not be loose. It should be staked from the factory. Check to make sure the bolts securing the key did not rotate past the staking. The bolts should be torqued to 35-40 in/lbs.
4) Check the gas rings. (or just go ahead and change them – they are very inexpensive) Mythbuster: The gaps in the gas rings do not need to be staggered. I know we were all taught otherwise in recruit training, and yes I know it says they must be staggered in the GI manual. But this is a myth. As a note; it will not hurt the system to stagger the gaps in the rings, but if this single change makes the difference – you need new gas rings ASAP. Inspect the rings, make sure there are 3 of them, and that they are installed properly. Disassemble the carrier group, insert the bolt into the carrier, and hold the carrier vertically in the air. The bolt should not fall out of the carrier.
5) Change the gas tube.
Failure to Feed
A failure to feed initially looks similar to a short stroking problem. A round is fired, a spent case is extracted and ejected, but the bolt is closed on an empty chamber. The difference with a failure to feed is that the bolt did travel far enough to the rear to chamber a round. But it did not, and it is now closed on an empty chamber. Generally speaking, this is most often caused by a defective magazine (specifically a problem with the feed lips). You might also notice 2 dents in the casing that is still loaded in the magazine from bolt over-ride. The solution is to replace the magazine. USGI magazines are class 9 expendable and should be replaced when defective.

Have you tried shooting your upper on your dads lower?
Lol no need to get so technical. He understood my point and meaning.
Just because he understood it doesn't make it right. It's just one of those things that drive me ****ing nuts. Like when people put u instead of typing you, or ne instead of any. Or when people use the wrong there/their/they're.
I understand.
I use rifles as firearms as an investment. Cheaper to get a rifle then an ounce of gold. I get a discount cause im the leprechaun and gold is still high.
Your built (best parts available) vs. Something that says COLT on every part. Ten years down the road value wise the built rig is damn near worthless.
I bought the .22 as a shooter because it was a steal at $350. And cheap to run 1k rounds through it.
If I was looking for a toy. I would definitely build my own though and it would be a 7.62.
Not true at all. Sure it may not be as easy to sell. You need a build sheet and a buyer who knows AR's. Ten years down the road your Colt will be worth a grand, same as it is today. Ten years down the road my built rig will be worth 2K, same as it is today.
Ever since the Fed assault weapons ban expired in 2004 there has been a huge influx of AR manufacturers to the market. And that is not likely to change any time soon.

My point is the AR 15 isn't going away any time soon, and high end parts demand a premium price now and they are going to demand a premium price 10 or 20 years down the road too.
