How does AR-15 firing pin work?
The AR-15 fires from a locked bolt, meaning that when a cartridge is chambered, the bolt closes behind the case and rotates 15 degrees: the lugs on the bolt head engage the protrusions on the barrel extension, solidly locking the bolt in place, so it can withstand the high pressure produced by powder combustion.
How does AR-15 Extractor work?
The extractor is essentially a spring-loaded claw that snaps over and into the rim of the cartridge case. Its job is to pull a fired case out of the chamber. If extractor tension gets too high, it doesn’t hurt extraction, but it hammers the case head as the round is chambered.
Can an AR-15 fire without a firing pin?
The AR-15 has a hard-hitting hammer that is required to force the titanium firing pin into the primer hard enough to fire the weapon. That hammer doesn’t touch the free-floating firing pin during chambering of a round or when the rifle is dropped.
Do you oil AR firing pin?
The cam pin needs just a little dot of oil or grease just above the firing pin hole. Rub in the lubrication until it is lightly coated and wipe off any excess. In the past, many shooters would completely coat the bolt carrier with oil or grease. This is not truly necessary.
Why is my AR-15 not firing?
The main causes for this type of malfunction are fouling of the bolt carrier group, fouling of the chamber, and a weak or broken extractor spring. In the case of the first two you’ll simply need to clean them up before resuming fire, but if it is the spring you’ll need to purchase a new one.

Why is my ar 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.
Is .223 and 5.56 ammo the same?
223 rounds are virtually identical in size to 5.56mm rounds. 223 ammunition will chamber and fire in a 5.56mm chamber and vice versa. However, the biggest difference between the two is that 5.56x45mm ammunition is loaded to a significantly higher pressure than . 223 Remington ammunition.
How many feet per second does an AR-15 shoot?
The 9mm handgun is generally regarded as an effective weapon; its bullet travels at 1,200 feet per second and delivers a kinetic energy of 400 foot pounds. By comparison, the standard AR-15 bullet travels at 3,251 feet per second and delivers 1300 foot pounds.
Do handguns have firing pins?
Firearms that do not have bolts, such as revolvers and the majority of single-shot firearms, generally have a very short firing pin in the action frame, or else attached to the hammer itself. Strikers are most commonly found in semi-automatic pistols and bolt-action firearms.
Can you remove a firing pin?

What is a floating firing pin?
How does a Free-Floating Firing Pin Work? This “Free Floating Firing Pin” is used in many Russian rifles like AK, SKS, RPD, SVD, RPK, PKM, etc. “Free Floating Firing Pin” doesn’t have any spring or cocker attached to it so the Firing Pin kinda floats freely inside the bolt.

What does the forward assist on an AR-15 do?
The forward assist on a firearm is a button found commonly on AR-15 rifle derivatives, such as the M16 rifle, and is usually located near the bolt closure. When hit, it pushes the bolt carrier forward, ensuring that the bolt is locked.
What does the buffer do in an AR-15?
The buffer & buffer spring is what it’s pushing into, and what returns the BCG forward, stripping and loading the next round. Of all the parts in the AR15, this is about the simplest. It’s a spring and weight combination, that until the past 20 years, went largely unchanged.
Is my AR Overgassed?
The signs of an over gassed AR-15 can include: Ejection issues: When the gun functions as designed, the bolt carrier group pulls the spent shell casing from the chamber and ejects it. Feeding issues: The bolt needs to have free movement to eject spent brass, and to collect a new round from the magazine.
