The maxim defense pdx pistol 7.62 x 39mm 5.5in black is a compact AR-style pistol built for tight quarters and hard use. It measures just 18.75 inches overall and uses a 5.5-inch threaded barrel with a pistol brace. Made from anodized aluminum, it stays light and tough where you need it most.

Key features
- SCW system — Why it matters: This 4-inch brace system with integrated bolt carrier group and interchangeable buffer weights cuts recoil and speeds up follow-up shots, so you stay on target faster.
- 5.5-inch threaded barrel — Why it matters: Short enough to maneuver in a truck cab or tight corner, with threads ready for a suppressor or muzzle device.
- HATEBRAKE muzzle booster installed — Why it matters: Reduces perceived recoil and keeps the gun flat during rapid fire, even with hot 7.62×39 loads.
- Anodized aluminum construction — Why it matters: Resists rust and wear from sweat, mud, and rough handling without adding extra weight.
Who it’s for
Ranchers who need a compact gun for predator control around the barn or feedlot. Rural workers who want a truck gun that stows small but hits hard. Anyone who spends time in tight spaces and refuses to carry a full-length rifle.
Pros/cons
- Pro: Extremely compact — fits in a backpack or behind a truck seat easily.
- Pro: 7.62x39mm gives you more punch than 5.56 at close range.
- Con: The 5.5-inch barrel limits effective range past 200 yards; this is a close-quarters tool, not a prairie rifle.
Comparison
| Feature | Maxim Defense PDX 7.62×39 | Zev Technologies OZ9C | Agency Arms AOS Glock 19 |
|---|---|---|---|
| Caliber | 7.62x39mm | 9mm | 9mm |
| Barrel length | 5.5 in | 4.0 in | 4.0 in |
| Overall length | 18.75 in | 7.5 in (pistol) | 7.5 in (pistol) |
| Weight | 5.2 lbs | 1.8 lbs | 1.7 lbs |
| Brace included | Yes (SCW) | No | No |
| Price | $2,245.50 | $1,200 | $1,500 |
The PDX is heavier and pricier than a standard handgun, but it delivers rifle-caliber power in a smaller package. The Zev and Agency options are fine for sidearm duty, but they don’t match the PDX’s close-range stopping ability.
FAQ
What is the overall length of the Maxim Defense PDX pistol?
It measures approximately 18.75 inches from the end of the brace to the tip of the barrel. That includes the 4-inch SCW brace system.
Can I use standard AR-15 magazines with this 7.62x39mm PDX?
No. You need dedicated 7.62x39mm AR magazines, like those from C-Products or ASC. Standard AR-15 mags won’t feed the larger cartridge reliably.
Does the HATEBRAKE muzzle booster help with recoil?
Yes. Per Maxim Defense specs, the HATEBRAKE reduces perceived recoil and helps keep the muzzle flat during rapid fire. It’s installed under the handguard so it doesn’t add length.
Is this firearm legal to own in all states?
It’s classified as a pistol under federal law, so it’s legal in most states. Check your local laws on pistol braces and barrel lengths before ordering. According to industry data, over 40% of US gun owners now own at least one AR-style pistol.
