what does it mean to blue print a rifle?

700 front finished — Blueprinted 700 action.

Blueprinting, or truing a rifle activity ensures the receiver face, threads, lugs, bolt lugs and bolt face up are square to the center line of the receiver.

In this article, we will start with a new Remington 700 short action receiver with a 308 commodities face up. We will exist performing the post-obit steps in this lodge:

Disassembly
Ream minor diameter of receiver threads
Foursquare the receiver lugs
Square the face of the receiver
Lap the bolt lugs
Square the bolt face

We ordered the following tools from Brownells to accomplish this task:

Remington 700 Armorer's kit
Receiver accurizing kit
Bolt lapping kit
Bolt confront truing tool
Receiver band facing cutter
Silicone carbine abrasive kit
Do-Drill cut oil
Multi-Vise with jaw pads

This article highlights our projection and is presented for data purposes simply. This provides an overview of the procedure and should non be attempted without the guidance and supervision of an experienced gunsmith.

After a few more turns the front of the receiver is now square. — Afterward a few more turns, the forepart of the receiver is at present square.

Next, we will lap the lugs of our Remington 700 using the bolt lapping tool. The tool, screws into the front of the action applying rearward pressure on the bolt face. The lugs, now contacting the newly square receiver lug surfaces, and can be lapped into place. — Next, we will lap the lugs of our Remington 700 using the bolt lapping tool. The tool screws into the front of the action and applies rearward force per unit area on the bolt face up. The lugs, now contacting the newly square receiver lug surfaces, can be lapped into place.

600 grit silicone carbide lapping compound is used to lap the bolt lugs.

A little bit of lapping compond is placed on the front of the receiver lugs. The bolt handle is then raised and lowed. Periodically we check our work. It is critical that we do not get any lapping compound on any other area. — A little bit of lapping chemical compound is placed on the front of the receiver lugs. The bolt handle is then raised and lowered repeatedly. We periodically bank check our work. Note; information technology is critical that nosotros practice not become any lapping compound on whatever other surfaces.

Note the shiny surfaces that have been trued. Once we have about 95% contact, we are finished. — Notice the shiny surfaces that have been trued. Once we have about 95% contact, we are finished. We and then rinse all areas with TCE to remove whatsoever remaining abrasive.

This tool will be used to true the bolt face. — The commodities face truing tool consists of a carbide cutter (bottom) and a tooling block (top).

The guide is screwed into the receiver. The carbide cutting tool is then snapped underneath the extractor with a little bit of Do Drill. The action is held horizontally in a padded vise. The bolt is inserted into the rear and the tool is pushed through the hole in the guide. — The tooling block is screwed into the receiver.
