Description
The Radical 5.56 7.5″ BLK 30RD MGPL BRC is a compact AR pistol built for tight cover, truck cabs, and quick handling in the field or at the range. Chambered in 5.56 NATO, this 7.5-inch-barreled platform from Radical Firearms uses mil-spec upper and lower receivers and their 7-inch RPR free-float rail to keep your support hand cool and give you room for lights, lasers, or a foregrip. It comes with a 30-round magazine and a black finish that won’t glare when you’re glassing a ridge at dawn. At $485.59, it’s a solid entry-level AR pistol that doesn’t cut corners on the parts that matter.

Key Features
- 7.5″ M4 Profile Barrel – The carbine-length gas system and 1:7 twist stabilize heavier bullets (62-77 gr) for reliable expansion on hogs or coyotes inside 150 yards. That twist rate also handles M855 ball ammo without keyholing.
- 7″ RPR Free-Float Rail – The Radical Precision Rail gives you a full-length Picatinny top and M-Lok slots at 3, 6, and 9 o’clock. You can mount a light, laser, and grip without touching the barrel, which keeps zero tight on your optic.
- MIL-STD Upper and Lower Receivers – Forged 7075-T6 aluminum meets mil-spec dimensions, so you can swap triggers, stocks (with a brace), or buffer tubes from brands like Geissele or BCM without fitting issues.
- 30-Round Magazine Included – Comes with a standard 30-round Magpul-style polymer mag. You get one in the box, so you can load up and head out the same day.
- Black Anodized Finish – The Type III hardcoat anodizing resists scratches from brush, truck beds, and gun cases. No rust worries in wet deer camp conditions.
Who It’s For
This AR pistol is for hunters who need a compact truck gun for coyotes, hogs, or varmints in thick cover. It’s also a solid choice for shooters building their first AR pistol who want a reliable, accurate platform without spending $1,000+. If you’re a three-gun competitor or a precision shooter, the 7.5-inch barrel limits velocity and effective range compared to a 16-inch carbine, but for inside 150 yards it’s fast and handy.
Pros & Cons
- Pros: Affordable price point for a complete pistol; free-float rail improves accuracy potential; mil-spec parts mean easy upgrades; includes a 30-round magazine.
- Cons: The 7.5-inch barrel produces significant muzzle blast and flash, especially with 5.56 ammo. A muzzle brake or blast can is recommended if you shoot indoors or near others. Accuracy at 200+ yards is limited by the short barrel’s velocity loss (roughly 200-300 fps slower than a 16-inch barrel).

FAQ
Is this AR pistol legal in my state?
This pistol ships as a firearm (not a rifle) with a pistol brace or buffer tube. Check your state and local laws regarding barrel length, magazine capacity, and pistol classifications. Radical Firearms follows ATF guidelines for pistol builds.
What ammo should I use in a 7.5-inch barrel?
Use 5.56 NATO or .223 Remington with bullet weights 55-77 grains. Heavier bullets (62-77 gr) stabilize better in the 1:7 twist. Avoid steel-case or underpowered ammo; the carbine-length gas system needs enough pressure to cycle reliably.
Can I mount a suppressor on this pistol?
Yes, if you have a 1/2×28 threaded barrel (standard on this model). A suppressor will reduce blast, but the short barrel still produces high back pressure. A flow-through suppressor (e.g., Surefire SOCOM) works best to avoid over-gassing.
Does this come with a pistol brace?
Yes, the Radical Firearms 7.5″ pistol includes a buffer tube and a pistol brace (typically a SBA3-style brace). This allows one-handed shooting while staying compliant with NFA rules for pistols.
