M-16 cut away, inside America’s favorite rifle

I have been exchanging emails with Mark from Arizona Response Systems, LLC  about the cut away of the M-2 Browning Machine Gun I featured a few months ago. You can see that article by following this link.  After a few emails back and forth he sent me some photos of a M-16 cut away he did and gave me permission to share them on rangehot.com. Thank you Mark.

Mark did an excellent job on these cut aways, and I appreciate him letting me share them on my site. I know why they call him the “gun plumber”

I spent much of my youth involved with firearms and felt the call early on to the United States Marine Corps, following in my father's and his brother's footsteps. Just after high school I enlisted and felt most at home on the rifle range, where I qualified expert with several firearms and spent some time as a rifle coach to my fellow Marines. After being honorably discharged I continued teaching firearm safety, rifle and pistol marksmanship, and began teaching metallic cartridge reloading. In the late 1990s I became a life member to the National Rifle Association and worked with the Friends of the NRA. Around that time my father and I became involved with IDPA and competed together up until he passed away. I began reviewing firearms for publications in the mid 2000s and have been fortunate to make many friends in the industry. Continuing to improve my firearms skills and knowledge is a never ending journey in which we should all be committed. I am also credited as weapons master on a few independent films.

    1. It is not an “M4”. If anything, it is closest to a Colt Commando. Which would be the carbine form of an M16A1. Like an XM177 without the compensator.
      A long time ago, a customer with an Olympic MG was having all kinds of trouble with it. I suggested he replace the entire parts kit with a Bushmaster, as it would be cheaper than hours of diagnostic testing. He gave me the old parts kit. And I turned it into a cutaway on a post sample lower.

    2. How much engagement is there between the auto sear and hammer notch? Should the entire thickness of the sear be on the notch ?
