AR 15 Builds
Updated with new ballistic data! The AR9 is the perfect pistol-caliber variant of the AR-15. Let's cover how to build one. We'll go over what parts the 9mm shares with the original AR-15, and what you need to swap to complete your build or conversion. We're also going over barrel length, twist rate, and parts compatibility. Take a look.
James Madison Tactical's polymer 80% lower includes the jig with templates for successfully cutting and drilling the receiver to make it functional, ready for a lower parts kit install. Before we get started, you'll need a number of bits and tools. These instructions are applicable for the JMT polymer .308 lower, too.
The 6.5 Grendel and 6.5 Creedmoor now compete among a few other loads (plus 6.5 PRC and 6.8 SPC thrown in), to earn the title as top 6.5mm cartridge for the AR-15 rifle. Is one better than the other? Which one should you get? We're comparing both cartridges' ballistic data and performance, weighing their pros and cons.
For this guide we're completing a forged AR-15 80% lower. These steps also apply to completing a billet and AR9 lower. We're also using the popular Elite Builder Jig, which comes with end mill bits and drill bits. These instructions will cover how to complete your 80% lower using either a drill press or milling machine. If you're ready to build an AR-15 from scratch, this is the proper way to get it done.
Learn how to install your AR-15's barrel and gas system! We've got some bad-ass instructions (detailed, with torque specs and tools) and up-close pictures to show you all the little details. Figure out what punches you need for the gas block roll pins, and how to properly "season" your receiver's threads and torque the barrel nut for reliability and MOA accuracy. This guide covers 5.56/.223 and 300 Blackout barrels.
A step-by-step picture guide! Installing the LPK in your AR-15's lower receiver should take less than two hours for first-time builders. This guide will illustrate how to perform each assembly and install step with pictures and written instructions. We strongly recommend finding the right tools before you get started, lest you end up with missing roll pins and springs that flew off into the carpet, never to be found again (you don't want to put a pause on your install half-way through).
So, you wanna build an AR-10. But where do you start? Even many "veteran" shooters don't realize the modern "AR-10" is not the original ArmaLite platform. DPMS largely supports the .308 AR game, now. This guide compares DPMS' LR-308 with the O.G. Stoner rifle, including parts compatibility, performance, cost, configuration, and proper setup.

And now you can grab this kit while it's on sale for just $350! Add a billet or forged 80% lower and grab a jig to have everything you need in a single order!

The AR platform can chamber a number of rounds with just slight modification: 300 Blackout, 5.56 NATO or .223 Remington, and .308 Winchester (technically called an “AR-10” or “AR-308” by builders), just to name a few. We reviewed and broke down the performance and ballistics data of these rounds with comparisons, so you can decide which one you want to build next! Check it out.
Grab this Classic A2 Rifle Build Kit for only $410! Includes a mil-spec, 4150 CMV barrel for MOA accuracy. Nitrided for superior performance (it's even better than chrome lining).

This is the intro and beginner’s guide to building an AR-15 in 300 Blackout. We’ll look at the history of this round first. Then we’ll review parts compatibility, barrel length and twist rate, and gas systems. You’ll know everything you need to pick out the right parts. We’ll also go over ballistics data and compare performance to other common AR-15 rounds.
It's 2019, and every day we stray further from the light. The black rifle deserves better than this. Spread the truth by building one and mastering the AR-15 yourself! Build kits are on sale and ship straight to your front door with ALL the parts you need! Grab an optional 80% lower and jig, and you can hit the range the same day your box o' parts shows up.
Getting a girl's number ain't really getting lucky. If you're idea of getting lucky (or let's face it, having skill) is putting a 0.5" shot group on paper at 100 yards, you've come to the right place. Every 1911, Austrian poly pistol, and AR-15 build kit we sell includes a mil-spec barrel made from 4150/CMV or 416R stainless steel.
Yes, classic quality and affordability can be had in one kit. This A2 build kit features a top-tier, cold hammer forged barrel made from mil-spec 4150 CMV. The barrel is finished off with a Melonite (nitride) finish, providing superior barrel life and accuracy compared to a phosphate and chrome-lined finish. The mid-length gas system and M16 BCG keep things running smoothly. The barrel's topped off with an old-school drop-in A2 handguard. Includes lower parts kit and optional 80% lower!
