The customer had asked if they could come and watch key stages of the build and who am I to argue even if it is an unusual request. Luckily I know them very well.
The original XM177E2 had the casting mark ground off on the rear of the base and the bayonet lug removed, so that is what I did. Note the tear drop forward assist on the main rifle picture, I am trying to get a look as close as possible to the original rifle.
The profiling went well although I did opt for a fine finish contrary to the original, I just could not live with the thought of building something that looked like it has been roughed out with a rasp on a Pole lathe…
I need the butt stock to arrive and we can then complete the assembly and run a couple of test rounds through it, then Cerakote and off to Proof. Oh, I also need to complete the muzzle device/sound moderator. I have decided to build it in three options:
1. Standard and 100% correct to the original Colt drawings.
2. Standard looking but for a spigoted barrel to give an 11.5″ overall look (XM177E2)
3. Standard looking but for a spigoted barrel to give an 10.0″ overall look (XM177)
I wonder how many people machined a barrel to the correct M177E2 profile today.
The picture shows the M177E2 11.5″ barrel look and the roll of hockey tape is there to hold the FSB up as it was just starting to rotate under its own weight which I think is a reasonable fit considering it will need painting.
