Remington 700: Fitting the barrel

Back to the Remington 700 project. I finished the barrel and the blueprinting of the bolt and the receiver. It is now time to fit the barrel and test fire the rifle. The masking tape you see in the photos is to protect the action from scratches.

Taped and ready to go

The Remington 700 receiver is easy to damage if twisted. To prevent damage like this I use a wrench adapter that I made during our first semester.

Once I installed the wrench adapter, I clamped the barrel in a barrel vice (yes, I made one of those in my first semester but the one you belongs to the school) and use an action wrench to tighten the barrel. Yes, the action wrench you see was a first semester project. Normally, I would use an a tool to hold the recoil lug in alignment during this step, but it was not needed as the action would be removed from the barrel after the test fire.

Ready to tighten

Once this was done, I installed the trigger and the rifle was ready to test fire.

Next was the test fire! Test firing consists of three rounds fired from the rifle. After the test fire, the cartridge cases are checked for expansion. We are allowed an expansion of 0.002 inches (0.0508mm or 50.8 micron). Here is a video of the test fire.

The results of the test fire was good. Zero case expansion. I am more than happy with that. The next step for this rifle is to install a muzzle brake and I will detail that in the next post.

    As I recall that 700 is in .223. Why a muzzle brake? Thats not a hard recoiling round.

    Eager to see if the brake is integral (I guess that would be called ported) or threaded.

      The muzzle brake just sort of happened. The short story is that I had it and my other rifles were crowned already. So this is where it went.
