Range Envy: 10 Really Cool AR-15s

All tan AR-15 built by Black Rain.

The ArmaLite-designed Colt AR-15 rifle has been changed, modified, experimented-on, improved and enhanced in such varied ways since its 1963 début that no one on this earth can tell you how many mods this black rifle platform has seen.

Based on Eugene Stoner’s 7.62x51mm AR-10, traditionally the AR-15 is chambered for 5.56mm/.223 Remington and operates from either a direct gas impingement or piston-driven system. From there, manufacturers and individuals have taken liberties with the AR’s basic design and aesthetics. For example, Windham’s VEX-SS with forest green laminated wood stock is barely recognizable as an AR-15 and Troy Defense’s new Troy Sporting PAR rifle isn’t even an AR at all! Many AR builders are making rifles in .300 Blackout or 6.8 SPC, while pistol calibers are popular, as well.

From pink to camo to flat dark earth, it isn’t just the finish manufacturers are playing with. Innovations in stock designs, rails and handguards, many are constantly trying to raise the bar in making every aspect of the AR-15 more reliable, more accurate and better suited to individual shooters needs. Most AR-15s share similar aesthetic features. The modularity of the platform is what makes it so adaptable to custom specs and AR manufacturers’ whims. You may think your handpicked piece-by-piece home-built AR is the coolest, but these 10 really cool factory ARs will give your rifle a run for its money.

1. KE Arms USM4 Mode 3 Select Fire

What makes it especially cool?

The Tac-Con rapid-fire trigger and KE Arms donates a portion of sales to help Special Force veterans and their families

The KE Arms USM4 Mode 3 select fire semiautomatic rifle has the Tac-Con rapid-fire trigger installed.

The KE Arms USM4 Mode 3 select fire semiautomatic rifle has the Tac-Con rapid-fire trigger installed and three select fire modes—safe, fire and auto. The Tac-Con’s 3MR trigger is 100 percent legal to own without a Class III license or tax stamp. That’s because Tac-Con’s 3MR trigger shoots in semiauto mode only. However, it allows for an “incredibly positive reset,” allowing the shooter to rapidly fire the rifle. The USM4 Mode 3 rifle has a 5.56mm chrome moly vanadium MIL-SPEC chamber and a 16-inch cold hammer-forged, high-pressure tested M4 barrel. The lower receiver is machined from billet 7075-T6 aluminum while the upper is machined from 7075-T6 aluminum forgings. Both the upper and lower receiver have NP3 nickel-Teflon coating. KE Arms uses its own U.S.-made H2 buffer. The USM4 Mode 3 select fire rifle has a VLTOR charging handle, A.R.M.S. rear folding sight, Magpul pistol grip, trigger guard and stock, and a KeyMod handguard. It comes with five Magpul PMAGS.

The Tricon MK6 has the best trigger you can find on an AR-15—the Super Tricon 2-stage trigger.

For a rifle where you do not need to upgrade a single part, check out LWRC’s Tricon Mark 6 semiautomatic rifle. Working with Geissele Automatics, the Tricon MK6 has the best trigger you can find on an AR-15—the Super Tricon 2-stage trigger. Geissele Automatics incorporates a MIL-SPEC pin and stainless steel springs on its trigger. The trigger is straighter at the bottom with a serrated front. The first stage has a 2.5-pound pull and the second stage has a 2-pound pull with an overall total trigger pull weight of 4.5 pounds. This limited run rifle features a unique spiral fluted barrel that lightens the weight of the barrel at the muzzle. It is 14.5 inches long with a permanently attached flash hider making the barrel a legal 16 inches overall with a 1:7-inch twist. Firearms trainer and former U.S. Navy Seal Jeff Gonzolas hand-selected each LWRC Tricon MK6 AR feature. The LWRC Tricon Mark 6 has a Bravo Company Gunfighter Gen 4 charging handle, SOPMOD stock and a MIL-SPEC safety. Chambered for 5.56mm NATO, the MK6 includes a 30-round magazine. This short-stroke piston operated AR-15 by LWRC also has Magpul sights, pistol grip and trigger guard. It includes a custom-designed rifle case and sling.

3. H&K MR556A1

What makes it especially cool?

The extremely reliable H&K 416 short-stroke gas system

The rifle’s operating system incorporates a solid operating push rod that replaces the gas tube found on all other AR-15 rifles—an operating system proprietary to H&K.

Based on the H&K 416 rifle—the rifle used to kill Osama Bin Laden, the H&K MR556A1 is the first opportunity for civilians to own one of the legendary rifles. The rifle’s operating system incorporates a solid operating push rod that replaces the gas tube found on other AR-15 rifles—an operating system proprietary to H&K. Also exclusive to the MR556A1 is the H&K diopter sight system with a fixed front and rotating drum with V-notch rear sight. Built in the United States with U.S.- and German-made parts, the H&K MR556A1 spent five years in development. The German produced parts include the 16.5-inch cold hammer forged barrel (not chrome lined), bolt assembly, fire control group and handguard. Every part on the H&K MR556A1 increases the rifle’s accuracy and reliability from the bolt carrier group and tungsten-filled buffer—that helps reduce recoil—to the two-stage trigger and collapsible H&K stock. The H&K MR556 also has a free-float rail system handguard and uses 20 or 30-round Magpul “E” mags.

4. WMD Guns “The Beast”

Chambered in 5.56mm NATO, the made-in-the-USA WMD Beast has a 16-inch match-grade chrome moly vanadium steel barrel with a 1:7 twist. The lower receiver is constructed of billet 7075-T6 aluminum and the upper is made of MIL-SPEC 7075-T6 aluminum forgings.

Rock River Arms built the LAR-15 to famous hunter Fred Eichler’s specifications specifically for varmint hunting.

Rock River Arms built the LAR-15 to famous hunter Fred Eichler’s specifications for varmint hunting. What stands out on this rifle is the tan furniture and rails, but most importantly, the specially designed Rock River Arms-made muzzle brake that has no venting underneath. Fred requested the special muzzle brake so the rifle does not kick up dirt, sand or debris when fired. Fred Eichler’s Predator series AR-15 from Rock River Arms has a .223 Wylde chamber. The .223 Wylde is a reamer used in the making of the chamber for the barrel to safely and reliably shoot both .223 Remington and 5.56mm NATO ammo. Rock River Arms forges both the upper and lower receivers in-house. The LAR-15 has a 16-inch cryo-treated, free-floating stainless steel heavy barrel with 1:8 twist. There is a big latch on the BCMGunfighter charging handle for ease of use. The enlarged trigger guard houses a two-stage, 3.5-pound trigger.

The Windham Weaponry Varmint Exterminator VEX-SS rifle features a 5.56 Compass Lake chamber.

The Windham Weaponry Varmint Exterminator VEX-SS rifle features a 5.56 Compass Lake chamber. This chamber has a leade that is shorter than 5.56, but not as short as .223 Remington. Further, the angle of the rifling is slightly different than standard, the overall dimensions are tighter and the bolt is matched to the chamber. This makes a more accurate rifle. Many competition shooters use a Compass Lake chamber. The VEX-SS is a gas impingement AR-15 with a 20-inch fluted precision 416R stainless steel heavy barrel with a 1:8-inch twist, target muzzle crown and bead-blast non-reflective finish.
