M-16 VS AR-15 PARTS

We are thankful to the many parts suppliers for providing the following photographs that clearly depict the differences between M-16 parts and AR-15 marts. The parts that we are concerned with are

1                     Bolt carrier

2                     Hammer

3                     Trigger

4                     Disconnector

5                     Selector Lever

In figure I we see both an M-16 bolt carrier and AR-15 bolt carrier. The only difference is where the AR-15 carrier has more machining in the are that contact the auto sear. The lip more the flower surface of the M-16 carrier contacts the auto sear as it nears its forward travel into battery and if correctly timed. Will release the hammer just as the bolt rotates into full battery position.

The notches on the side of the carriers are to facilitate using the forward assist plunger if your upper receiver is so eauipped. Normally a factory AR-15 does not have a forward assist. If an AR-15 carrier contains these notches as dose the one pictured here, it denotes that it was manufactured from as existing M-16 carrier. In figure 2 is shown an M-16 bolt carrier – chrome plated but without forward assist notches.
