AR-MPR- RCBS Rifle Bullet Feeder Overview Part II

Recently, I gave a quick overview of the RCBS Rifle Bullet Feed System. In that post, I gave an overview of what’s included in the kit. In this post, we’ll take a look at what this system looks like installed on a 5-Station reloading press (The RCBS Pro-2000 in this case). As you can see […]

AR-MPR- RCBS Rifle Bullet Feeder Overview

Phase III of the AR-MPR AR-15 rifle project is really all about “precision mass production” of the ammunition that we’re developing in Phase II (precision single stage loading). There are a couple key things that we’ll explore: first, we’ll look at progressive reloading of .223 / 5.56 ammunition. We’ll also extend our production rates by […]

AR-MPR Phase II – Checking and Correcting Bullet Concentricity

If you are a precision shooter, you care about consistency for the cartridges that you shoot. One of the most important factors to measure and control when reloading match ammunition is bullet concentricity. Simply stated, this is the alignment of the case and bullet. If you have “good concentricity”, you will have the axis of […]

AR-MPR Phase II – Seating Bullets

In this video, we’ll use the Hornady OAL Gage measurements from our first Phase II loading video: AR-MPR: Phase II – Determining Max COL with OAL Gage and measure the dimensions of the cartridge and magazine to determine the optimal bullet seating depth for the bullet and rifle in question. We’ll then use the Redding […]

AR-MPR – OnTarget Software – Measure Groups Easily

For AR-MPR, I’m chasing a .5 – .75 MOA accuracy goal. Initially, I started with 3-shot groups when I function tested the rifle, but have upgraded the challenge to “consistent 5-shot groups at .5 – .75 MOA”. In order to track my progress, I’ve taken a hint from Paul over at http://accurateshooter.com – use the […]

AR-MPR: Phase II – Magpul PRS Stock and XTM Rail Panels Install

One of the important aspects of a precision rifle is the overall rigidity of the entire rifle – the action, barrel, stock, and other components – the entire unit must be solid in order to shoot with maximum precision. The AR-MPR rifle was initially put together with an M4-Style 6 position collapsible stock. This imposed […]

AR-MPR: Phase II – Charging Cases with the Redding 3-BR and Hornady Auto Charge

In this video we’ll continue the precision loading process by using the Redding 3-BR powder measure and the Hornady Auto Charge to dispense powder loads. Next, we’ll cover calculating optimal seating depth, and seating the bullets. Thanks, Gavin http://ultimatereloader.com/wp-content/uploads/2010/11/AR-MPR-logo-wide-small.jpg

AR-MPR: Phase II – Rifle Accurizing Plans

I just read a great article written by Robert Whitley of www.6mmar.com fame that was posted on the  http://accurateshooter.com blog: What Makes an AR Accurate — Whitley Offers Answers Talk about good timing! This post helped me plan the first wave of accurizing activities for the AR-MPR rifle. My goal is to remove any factors […]

AR-MPR: Phase II – Sizing Depriming Priming .223 Remington

In this video we’ll start the precision loading process by lubing, sizing, depriming, and priming cases. We’ll walk through the features of the Redding Big Boss II, show how to lube .223 cases, validate sizing die setup, and then size/deprime/prime the cases. Next, we’ll cover charging the cases with the Redding 3-BR benchrest powder measure […]

AR-MPR: Phase II – Determining Max COL with OAL Gage

One of the important things to know before loading rifle ammunition is how far out (shallow) you can seat bullets, and what the optimized seating depth is for a particular bullet for your rifle and shooting application. For AR-MPR Phase II, we’re going for maximum accuracy, and also need to assure proper feed characteristics so […]

AR-MPR: Phase II Hornady Equipment Overview

In my last post, I gave an overview of some of the Redding equipment that we’ll be showcasing during Phase II of the AR-MPR project. I this post, I’ll cover some Hornady equipment that will also be used for this precision loading phase of the AR-MPR project. We’ll cover more Hornady gear (such as the […]

AR-MPR: Phase II Redding Equipment Overview

For Phase II of the AR-MPR we will be focused on precision handloading techniques and load development. For this phase of the project, I decided to showcase some of the popular Redding Reloading products that have an outstanding quality reputation. Here, we’ll talk briefly about each of these products. The Big Boss At the heart […]

AR-MPR: Phase II Kick-Off

Now that we’ve build and function checked the AR-MPR rifle (See Brownells Videos for Complete Details), it’s time to move from Phase I (Build) to Phase II – Precision Loading and Rifle Accurizing/Tuning. This rifle has already proven that it’s capable of meeting the original accuracy goal of .5 – .75 MOA (See Range Report […]

AR-MPR 1st Range Report – Unexpected Results

  The mission for the first range trip with the AR-MPR rifle was to really do two things: First, it was about function checking the rifle. Second, it was about sighting in the Nikon Monarch 6-24x50mm riflescope. A third and less important goal was to see how accurate I could shoot this rifle based on […]

AR-MPR: Build Part 7 – Lower – Buttstock and Mating Upper Lower

In this, the final AR-15 assembly video, we’ll walk through the installation of the takedown pin and the buttstock assembly. Finally, we’ll put the upper and lower together for the first time and establish basic functionality (formal function check to follow in subsequent posts). After all of the planning and work that went into getting […]

AR-MPR: Build Part 6 – Lower – Trigger Grip and Safety

Continuing our way through the lower build steps, in this video, we’ll look at installing the Geissele national match trigger assembly, the trigger guard, the safety selector lever assembly, and the pistol grip.       Next, it’s on to the stock and final touches! Thanks,Gavin  

AR-MPR: Build Part 5 – Lower – Magazine Catch Bolt Catch Pivot Pin

In this video, we’ll start the assembly of the lower by walking through the installation of the magazine catch, the bolt catch, and the pivot pin. You’ll see a trick for installing the pivot pin that makes use of a dulled razor blade, and a modified section of drill rod. From the video, in this […]

AR-MPR: Build Part 4 – Upper – Bolt Carrier Group and Headspace

In this video, we’ll put the final touches on the upper assembly by walking through the assembly of the Bolt Carrier Group (BCG), checking headspace, and finally installing the BCG and charging handle into the upper receiver. Note: Here, I show you how to check headspace with the extractor installed. You can also do this […]
