AR-15 Build: Dale Miller’s Precision AR-15

Building an AR-15 is a great way to get to know the platform. What’s fun is that you have an infinite number of combinations of the components and accessories that can be used to put together a finished rifle. But the fun doesn’t stop when you’re done. Swapping out uppers and lowers and also changing accessories is both easy to do, and can be practical as well.

Following the AR-MPR build on Ultimate Reloader, I helped some friends build AR-15 rifles. One of those friends was my neighbor, Dale Miller who runs Dale Miller Construction. His goals were similar to mine: an accurate AR-15 that would wear a scope, and be suitable for long-distance target shooting and varminting. I did a brief post on Ultimate Reloader on this rifle, and have had a lot of requests for more information, so here you go!

The build was a lot of fun, and the rifle shoots GREAT! Here is some information about the components that Dale selected:

Magpul PRS Stock

The Magpul® PRS™ (Precision Rifle / Sniper – AR15/M16 Model) is a drop-in, precision-adjustable butt stock for rifles with A1 / A2 fixed stocks. Designed to offer the fine-tuned, customized feel of a precision target stock, the PRS™ is adjustable for both cheek riser height and length-of-pull without sacrificing the durability necessary to withstand the operational environment. Compared to the A2 stock, the PRS™ can shorten the LOP by 0.25” or extend it by 0.75”. Machined aluminum adjustment knobs feature positive-locking click detents to maintain position under recoil and allows easy, tool-less adjustments by simply rotating the knobs. Machined aluminum butt-plate and alloy steel adjustment shaft provide stability and strength to withstand severe impact conditions. Rubber butt-pad offers positive shoulder purchase to prevent slippage for optimal accuracy even with body armor or modular gear. Bottom Picatinny-type rail allows for monopod use, additional sling mounts or storage. Stock includes all mounting hardware for A1 / A2 type rifles with fixed stock.

Designed with law enforcement, target shooters, and serious hunters in mind, the Millett Tactical Series scope features options not found on most scopes today. Side focus range knob is clearly marked and can easily be read from the shooting position, along with the 1/4 MOA windage and elevation adjustment marks. Ill. Mil-Dot model features adjustable green crosshairs for low light situations and also has a night vision setting. Heavy-duty 30mm aluminum tube is nitrogen filled to be guaranteed fogproof, waterproof and shockproof. Includes caps, sunshade and Millett’s Lifetime Guarantee.
