The Radical Firearms 7.62x39 AR rifle combines the popular .30 caliber cartridge with the ergonomics of an AR-15. This low-recoil, hard-hitting round is a joy to shoot on the range and performs well on the hunt and now you have the added benefit of modular AR-15 parts like a free float M-LOK handguard. The Radical Firearms FCR is extremely thin and lightweight while still offering you many options for customization. With the M-LOK attachment slots, you can easily rearrange your rifle set up with lights, grips, bipods, and more depending on the situation. This 15” handguard almost extends the full length of the 16” barrel, so you can put your weapon light as far forward as possible for optimal light coverage and grip further along the rail for better stability. The barrel is made from 4150 chrome moly vanadium steel and features a durable Melonite finish inside and out for a long barrel life. Outfitted to the end of the barrel is an A2 flash hider with a 5/8x24 thread pitch for compatibility with other .30 caliber muzzle devices if you want to upgrade. This Radical Firearms 7.62 AR-15 comes with all the features you want for a successful hunt or range day.

  • 16” 4150 chrome moly vanadium steel barrel chambered in 7.62x39
  • HBAR barrel profile with Melonite finish
  • 1:10 twist rate for stabilizing the heavier .30 caliber projectile
  • Melonite coated bolt carrier group
  • Carbine length gas system
  • .750 gas block diameter
  • Mil-Spec A2 flash hider
  • Forged 7075-T6 upper and lower receivers
  • Type III hardcoat anodized
  • Radical Firearms FCR M-LOK handguard
  • Ambi safety selector, Billet mag release, and extended bolt release
  • Mission First Tactical Minimalist stock and ergonomic pistol grip
  • Includes 20 round 7.62x39 magazine
  • Made in the U.S.A.

The 7.62x39 upper isn’t the only component packed full of features. The forged 7075-T6 lower receiver comes with an ambidextrous safety selector, billet magazine release, and an extended bolt release all made in house at Radical Firearms. It also features Mission First Tactical furniture like an ergonomic pistol grip and the popular Minimalist stock. Why spend the money buying a stock AR-15 only to spend more money upgrading it, when you can buy one with high quality aftermarket components already installed? With this Radical Firearms complete AR-15 style rifle, all you need is your favorite optic or iron sights and you are ready to head to the range.

Not sure what to make of the quality yet


Bought this on the cyber Monday sale. As soon as I received it I noticed the rail screws were hammered in so deep that I broke an Allen wrench trying to get it off to put an M-lok grip on. I even used a torch to try and hear them up and it did nothing. Immediately sent back to Radical. I think they used a 60,000 pound press to press the screws in? I’ll update the review when I get to shoot this thing.

Shoots great


I really like how this gun feels and shoots. It's reasonable and probably the main reason I bought it. Can't really go wrong at that price point. It does the job needed: pull the trigger, hits the target.

Good Value


Barrel and BCG are of good quality, especially given the QPQ/ Melonite/ Nitride finish.
<br>Giving this 4.5 stars, because the upper sounds a little tinny when manually cycling, and the trigger is quite gritty, but then look at the price point, especially given the barrel and BCG finish.
<br>Before firing, I did upgrade the hammer spring to a Wolf extra power spring, and also upgraded the firing pin to the enhanced firing pin from Red X Arms.
<br>That said everything worked well, and would definitely recommend to a friend or family member.
<br>Two people have the 5.56x45 versions and are equally happy with them.
