Frequently Asked Questions

What are the key steps involved in building an AR-15?

Building an AR-15 involves assembling both the upper and lower receivers. Key steps include installing the barrel nut, gas block, and flash suppressor on the upper, and the trigger guard, magazine catch, bolt catch, grip, and buffer tube on the lower. Proper use of tools like bench blocks and roll pin punches is essential.

What tools are necessary for building an AR-15?

Essential tools for building an AR-15 include a vice, gun mat, bench block, roll pin starter punch, hammer, various punches, and screwdrivers. A specialized T-handle kit and an interchangeable head hammer are also shown to be very useful for specific tasks.

How do you ensure the AR-15 safety mechanism works correctly after assembly?

After assembling the lower receiver, perform a dry fire test. First, place the selector in the 'safe' position and pull the trigger; the hammer should not fall. Then, move the selector to 'fire' and pull the trigger; the hammer should fall, and then reset when the trigger is released.

What are some common modifications or upgrades mentioned for an AR-15 build?
