M16A2 BUILD LOG

The Story

Ente has always been a firearms enthusiast and interested in history, especially World War I, World War II and The Vietnam War. Ever since he first saw the iconic profile of the M16A2 he wanted one of his own.

Why build one?

Well first of all, cost. An actual M16 can cost a pretty penny. Ente built his for less than $700 USD with new & reproduction parts.

(Tools not included in that price.)

Also after Ente built his M16A1 he figured it needed a friend, one is none right? He also enjoyed the M16A2 in Call of Duty Advanced Warfare & Black Ops Cold War. He also really liked the look of them in Black Hawk Down.

How did he do it?

Building the M16A2 was quite easy when it came to sourcing parts as they are still prolific and the rifle is still in service today.

Ente went to Luth AR to get the A2 Upper Receiver. Then He went to Palmetto State Armory to get a Stealth Lower Receiver and an A2 Freedom 20" Rifle Kit.

Ente went to Brownell's to get a Stanag 30-Round magazine, or 20.

After sourcing all the parts Ente had to remove the barrel from the A4 receiver and got to building. He ran into an issue part of the way through, his PSA parts kit came with 2 Hammer Springs and no Trigger spring. Luckily he had other parts kits around for other builds and after robbing one he soldiered on. PSA customer service was great and sent a replacement for the missing spring. After getting the rifle assembled he oiled all the friction surfaces and fire control group. After wiping away excess lubricant he used some OD Green Gaffer's tape on the stock and magazine emulating some of the rifles that have seen service.

After it was completed he used headspace gauges to check the chamber clearance to ensure the rifle was safe to operate.

Accessories

Ente sourced a barrel mount flashlight holder and got a Magpul MS1 Ranger Green Two-Point Rifle sling to use while carrying the rifle during training drills.

After a few months of research, careful planning, sourcing parts and tools, the build was finished.

A list of parts and tools used can be found below. For those who want to build their own M16A2.
