Are AR-15 parts universal?
Part of the reason the AR is so versatile is its modularity. The only part which is necessarily universal in this rifle is the lower receiver and some of its internal parts. Other than that, almost every part of the rifle is customizable to fit a department purchase or an individual officer’s needs.
What spare parts should I have for my AR-15?
Here are a few thoughts on must-have spare parts for your AR-15.
- Spring Set. A kit of spare springs, particularly hammer and trigger springs, can be a lifesaver.
- Pins. Hammer and trigger pins can also break.
- Bolt and Extractor.
- Gas Rings.
- Gas Tubes and Roll Pins.
When should I replace my AR15 parts?
Replace these parts on your bolt every 2,500 to 3,000 rounds. If you cannot justify an extra bolt carrier group, at least carry a spare bolt with you. If you are replacing your bolt carrier group every 10k rounds, you will not need to replace this, but it is not a bad idea to have one.
Can you put any upper on a lower?
Yes any standard lower can be attached to any standard upper. That’s the beauty of the ar. Be careful. If you attach a short barreled upper made for an ar pistol to a standard rifle lower you have just made a short barreled rifle.
Can all AR-15 parts interchangeable?
As we discussed in our past blog, the lower receiver is the actual firearm component of the AR 15 and the only serialized part, which means you can swap out any of the components on the upper assembly without going through all the steps necessary to buy a firearm each time you want a different component.
When should I replace my AR-15 gas ring?

What gun will replace the M4?

How long do AR-15 last?
The average life of an AR-15 barrel is about 20,000 rounds. Let’s generously assume that the average new shooter goes to the range once a month and fires 100 rounds through their rifle per session. At that pace, it would take about 16 years to wear out that barrel.
Can I put any AR-15 Upper on any lower?
No, combining upper and lower receivers of different brands will make no difference in accuracy whatsoever. On the other hand, the quality of your upper receiver certainly will.
