Key Features
- 16-inch 1:7 Twist Barrel: Why it matters – Stabilizes heavier match bullets (69-77gr) for tighter groups at 200-600 yards, critical for 3-Gun stages and precision gas gun matches.
- M-LOK Compatible Handguard: Why it matters – Allows direct attachment of bipods, lights, and barricade stops without extra rail sections. Keeps weight low and grip slim.
- B5 Bravo Synthetic Camouflage Stock: Why it matters – Locking, non-slip buttpad and a slim profile reduce felt recoil and snag on gear. The camo pattern also breaks up the rifle’s outline in field courses.
- Forged Mil-Spec Upper Receiver: Why it matters – Ensures consistent bolt carrier group alignment and barrel extension fit. No loose tolerances means better accuracy potential and gas system reliability.
- No Iron Sights Included: Why it matters – You’re free to mount your preferred optic (LPVO, red dot, or magnified) without paying for backup sights you’ll never use. Saves weight and cost.
Who It’s For
This rifle is built for competition shooters who want a reliable, accurate, and affordable entry into 3-Gun, tactical rifle matches, or steel challenge. It’s also a solid choice for precision enthusiasts who plan to upgrade triggers, handguards, or barrels – the forged receiver set gives you a strong foundation. If you’re a new shooter looking for a first AR-15 that won’t break the bank but still shoots straight, this is your platform.
Pros & Cons
- Pro: Price-to-performance ratio is outstanding – under $500 for a 1:7 twist, M-LOK, B5 stock rifle with a chrome-lined barrel.
- Pro: Lightweight at 6.5 lbs unloaded – easy to carry through long stages and transitions.
- Con: No iron sights included – you’ll need to budget for an optic or backup sights.
- Con: The trigger is mil-spec (6-8 lbs pull) – serious competitors will want to swap in a Geissele or Timney drop-in for faster splits.

FAQ
Does the Radical Firearms FR-16 come with iron sights?
No, the FR-16 does not include iron sights. You’ll need to mount your own optic or backup sights. We recommend a budget-friendly red dot like a Holosun 403B or a Vortex Crossfire for competition use.
What is the barrel twist rate on the FR-16?
The barrel has a 1:7 twist rate, optimized for stabilizing 55-grain to 77-grain bullets. This makes it ideal for both 55-grain plinking ammo and 77-grain match loads for precision stages.
Is the handguard free-float?
According to Radical Firearms specs, the M-LOK handguard is free-float. This improves accuracy by removing pressure on the barrel from the handguard. It’s a must for consistent shot placement in competition.
What magazines are compatible?
Standard AR-15/M16 pattern magazines work. The rifle ships with one 30-round Magpul PMAG. Any mil-spec or aftermarket mag (e.g., Lancer, Hexmag) will function.
Can I upgrade the trigger on the FR-16?
Yes – the lower receiver uses a standard AR-15 trigger group. You can drop in a Geissele SSA-E (for precision stages) or a Timney Impact (for fast splits). Expect a 50% improvement in accuracy and split times after upgrade.
