Apf 5.56 Nato M4 Pistol 11.5 Sba3 30Rd

The Alex Pro Firearms 5.56 NATO M4 pistol with SBA3 brace is a compact, AR-platform firearm built on forged aluminum receivers and designed for shooters who want the ergonomics and modularity of an M4-style rifle in a shorter, more maneuverable package. With an 11.5-inch barrel, this 5.56 NATO pistol is ideal for home defense, tactical training, or anyone seeking a handy, reliable AR pistol that doesn't sacrifice component quality or shootability.

Built on A1 forged 7075 T6 aluminum upper and lower receivers, this Alex Pro Firearms pistol uses a mil-spec trigger, M16 bolt carrier group, and a carbine-length gas system pinned to the barrel for reliable cycling. The 4150 CMV chrome-lined barrel is a solid choice for durability and easier maintenance. The A1-profile handguard includes an integral heat shield to protect your support hand during extended shooting sessions. Iron sights are included to get you running immediately, and the A2 flash hider helps manage muzzle signature and recoil impulse.

The SB Tactical SBA3 stabilizing brace secures the pistol to your forearm, providing additional control and consistency when firing. You'll receive one aluminum 30-round magazine with the rifle, and the gun weighs just 5.7 pounds—lightweight enough for all-day carry or training without fatigue. The entire platform is standard AR-pattern, so upgrades, replacement parts, and aftermarket accessories are readily available if you ever want to customize your setup.

Whether you're outfitting a truck, truck bed, or training for defensive scenarios, this 5.56 NATO M4 pistol delivers proven design, honest craftsmanship, and no-nonsense performance at a straightforward value.

Frequently Asked Questions

What magazines work with this 5.56 NATO pistol?

This Alex Pro Firearms pistol is a standard AR-pattern rifle, so it accepts all common 5.56 NATO AR magazines. One aluminum 30-round magazine is included with the gun; additional magazines are widely available from many manufacturers.

Can I upgrade or customize this M4 pistol?

Yes. The platform is standard AR-pattern, so the handguard, stock/brace, muzzle device, grip, trigger, and other components can be swapped for upgrades if you choose to modify it. The pinned gas block is part of the permanent carbine-length gas system.

What's the difference between this pistol and a short-barrel rifle (SBR)?

This is legally classified as a pistol because it has a pistol brace (SBA3) rather than a traditional stock. No federal tax stamp or registration is required. Always verify current federal and local laws before purchasing or modifying any firearm.

Is this suitable for home defense or training?

The 11.5-inch barrel and compact 30-inch overall length make it maneuverable indoors or in tight spaces. The included iron sights and mil-spec components provide reliable performance for defensive training or range work. Pair it with quality ammunition and regular practice for best results.
