Why does my AR-15 keep jamming?

You can misalign the ammunition inside the magazine or, if it’s backed by a strong magazine spring, you could even knock loose a round to try to jump into the chamber prematurely. Either of which will inevitably cause AR-15 jamming.

What causes the bolt to rotate in the bolt carrier?

As the bolt carrier moves forward, the bolt passes through cuts in the barrel extension and a cam pin causes the bolt to rotate, so that the locking lugs on the bolt are locked as the bolt reaches its forward most point.

Does bolt carrier group affect accuracy?

Tuning the gas tube for minimal contact through the receiver and in the gas key atop the bolt carrier group (BCG) not only reduces its potentially adverse affect on accuracy, it can aid reliability and smooth operation. Tuning a gas tube is a trial-and-error process.

What causes failure to extract?

A failure to extract occurs when the casing of the just-fired round is not successfully extracted from the chamber. This can be caused by an overly-dirty chamber, broken extractor claw, case rim failures, or several other causes.

Why does my gun keep jamming?

Failure to properly clean and lubricate your firearm can also cause it to jam. Sometimes, buildup on the feed ramp will cause a cartridge to stick and not load properly. Alternatively, there may be enough friction when not properly lubricated that the guns moving parts will seize up.

Why is my gun not cycling properly?

Cycling issues can be created by having a buffer that is either too heavy or too light. We recommend that you get an H or H2 buffer for your gun for safety. Another issue with the buffer spring is that it may be too old. An aged buffer spring can prevent the AR from correctly chambering the following round.

Why does my AR 15 only fire round?

While holding the trigger back, try to manually push the hammer back and lock it in the cocked position. If it fails to lock back, then the disconnector is not functioning as it should (which sounds like the case) or the disconnector spring is either weak or missing.

Why does AR-15 bolt rotate?

When the cartridge is fired, the bolt needs to rotate in the opposite direction and pulled back, so that the spent case can be extracted, ejected and a fresh round can be chambered.

How does AR-15 bolt catch work?

The rifle will easily chamber a round from a loaded magazine when you pull back the charging handle and release it. Then after you’ve fired your last round downrange, the bolt carrier locks to the rear so that you can quickly drop the spent mag, insert another one, release the bolt catch and get ready to fire again.

Are Anderson lowers mil-spec?

Anderson Manufacturing’s AM15 stripped lower receiver is a standard pattern mil-spec AR-15 lower receiver. This unit is constructed from forged 7075-T6 aluminum and features an ultra durable type III hard coat anodized per the military’s specification.

What parts make an AR accurate?

Building an Accurate AR — What is Most Important

  • Great Barrel: You’ll want a premium match-grade barrel, well-machined with a good crown and a match-type chambering, true to the bore and well cut.
  • Rigid Upper: A rigid, heavy-walled upper receiver aids accuracy.
