Apf 5.56 Nato M16A1 20 A2 Fixed 30Rd

The Alex Pro Firearms 5.56 NATO M16A1 is a classic modern reproduction rifle that combines proven A1/A2-era design with today's manufacturing standards. Built on a 20-inch chrome-lined barrel with a 1:7 twist, this rifle delivers the reliable accuracy and handling that made the M16A1 platform a workhorse for decades. Whether you're a vintage mil-spec enthusiast, a competitive shooter who appreciates fixed-stock ergonomics, or someone building a historically accurate clone, this APF rifle gives you genuine mil-spec components without the collector's price tag.

Every major component reflects authentic mil-spec specs: forged 7075-T6 aluminum receivers, an M16-pattern bolt carrier group, rifle-length gas system with pinned A1 gas block, and the classic A1 triangular handguard with integral heat shield. The fixed A2 buttstock and mil-spec trigger group keep things straightforward and reliable. Sights are A1 configuration—simple, robust, and purpose-built. The three-prong A1 flash hider tames muzzle blast while staying period-correct. You get one 30-round GI aluminum magazine in the box, and the whole package weighs just 7 pounds over its 39.5-inch length—nimble and controllable.

This is not a modern tactical rifle; it's an unapologetic nod to what worked. That matters if you value simplicity, durability, and a platform that rewards marksmanship over gear. A1 sights force you to actually aim. A fixed stock won't collapse when it shouldn't. A mil-spec trigger is predictable. Build around it, shoot it as-is, or use it as the foundation for a clone build. Alex Pro Firearms has delivered the bones; you can take it from there.

Frequently Asked Questions

Is this rifle suitable for 3-gun or competition shooting?

Absolutely. The A1/A2 configuration with a fixed stock and mil-spec trigger is used in many competition formats. The 20-inch barrel and rifle-length gas system provide reliable cycling and accuracy. You may want to upgrade the sights or add optics, but the rifle itself is a solid foundation.

Can I use modern tactical accessories with this rifle?

The APF M16A1 features a flattop-style receiver compatible with Picatinny rail mounts, so you can add optics, lights, and other modern gear as needed. However, the classic A1 handguard and fixed stock retain period-correct ergonomics. You can build this rifle to be as modern or as traditional as you like.

What's included in the box?

The rifle comes with one 30-round GI aluminum magazine. No other accessories, sights, or optics are included—just the rifle and magazine.

What ammunition does this rifle shoot?

The APF M16A1 is chambered in 5.56x45mm NATO and is fully compatible with .223 Remington ammunition as well. The 1:7 twist rate is optimized for heavier 5.56 NATO loads.
