Ultra Basic Super Simplified M16A1 vs M16 A2 guide
In the spirit of my AK Visual ID guide, I’ve again stolen pics from Google images, AR15.com, and a couple of my own pics, to make my own super easy basic layman visual ID guide for the A1 and A2 style ARs.
This will only cover very basic visual differences and will not get into SP1, or M16 vs M16A1, or any other variant discussion.
There’s a TON of M16 variants as you can see.
We’ll expand on the above pic.
This is a typical A1 style rifle
Now, my personal A2 style build
Some similarities, a few differences.
The A1 stock is roughly 5/8 of an inch shorter than an A2 stock
The A1 handguards will typically be triangular shaped…
..vs the A2 style rounded handguards
Original A1 grips are also smooth
A2 grips have the finger ledge
Also note, A1 and A2 furniture are interchangeable on most 20 inch barreled rifles.
The primary visual difference lies in the receiver, specifically the fixed carry handle of both.
The A1 carry handle lacks an elevation knob and has a much simpler windage adjustment.
The A2 style has very distinct elevation and windage adjustment knobs
Super simplified. Ultra Basic. Doesn’t even begin to discuss slab sides and M16A4s.
Oh well. I got tired of seeing the A2 tag on an A1 and vice-versa.
