AR-15 is a gas-powered, magazine-fed,
air-cooled, selective-fire, a lightweight rifle which was developed in the United
States by gun Manufacturer Company, ArmaLite in the year 1956. ArmaLite sold
its rights of the AR-15 rifle to Colt in the year 1959 due to some financial
problems and limited production capacity and manpower. Colt did some
modifications in the rifle, the most notable change was the charging handle
which was relocated to the back of the receiver from its initial position which
was under the carrying handles. This redesigned rifle was marketed to many
military services around the globe, after which it was adopted by the United
States military and was labelled as the M16 rifle.
AR-15 is the most popular rifle in the country
today. The high customization options are what makes is suitable for a wide
range of operating conditions, making it a highly preferred choice among gun
enthusiasts. Most of the components and parts of AR-15 and M16 are very
similar. Over the years many modifications have been done in both the rifles,
however, some parts can be easily interchanged, but it is not permitted as per
the law and order of most countries. Read through the blog to gain a quick
insight into few of the parts that are different in the M16 and AR-15 rifles.
Trigger:
Triggers of AR-15 and M16 are quite similar,
the only difference we have seen is that the AR-15 trigger has a closed channel
whilst the trigger of M16 features an open channel so that it could easily accommodate
the disconnector.
Disconnector:
AR-15 rifle has a couple of versions of
disconnector, one of the essential difference in the design of the disconnector
of M16 and AR-15 is that there is a tail at the rear of the disconnector for
M16, which is not present in that of AR-15.
Selector:
The selector of the M16 rifle is easily
distinguishable from that of AR-15 version. It features additional cutouts and
can be rotated to the auto, third position when in the receiver (aiming at the
rear), made possible by an additional index on the selector.
Hammer:
The hammer of AR-15 does not have a hook,
whilst M16 hammer is designed with a hook positioned at the upper rear extreme
for the auto sear.
Bolt Carrier:
The bolt carrier of M16 usually has about
2" closed section at the back that slides the auto sear into full auto
ammunition. The semi-auto versions of the rifle might have a completely open
bottom or a slightly closed bottom section, it is made in this way to prevent
the installation of an adapter with M-16 configuration. Another notable
difference in the bolt carrier of these two rifles is that the extra metal is
removed from the underside so that the collar of the firing pin can be exposed.
This helps in holding the hammer, therefore preventing firing if the carrier is
not seated in the exact position or is not fully forward when the hammer is
released. This happens when no auto sear holding the hammer back. In the M16
rifle, the firing pin collar of the bolt carrier is not exposed.
