### Key Specifications
- **UPC**: 680017478001

- **Action**: Semi Automatic

### Features

The patent-pending Maxim SCW Stock System collapses to just 4 inches, which is what makes the overall length figure possible without gutting the shoulder interface. The integrated BCG accepts interchangeable buffer weights, letting shooters tune the gas system for different loads or suppressor use. The Maxim Hate Brake muzzle booster is designed to redirect gases and concussion downrange, cutting both recoil and flash signature during rapid fire.

The 7.62X39MM chambering gives the PDX stopping power that most PDW-sized guns in smaller calibers can't match, though feeding reliability with some ammunition types is worth verifying during break-in.

> The practicality of 5.56 getting that short really limits you now it's still going to be lethal but I find that it's just it makes me violently angry.

> Look this takes AR mags and has 100% AR controls and delivers more of a punch than any pistol caliber carbine out there.

> Sometimes I've noticed upon dropping bolt it might just go like that it might just stop.

## What Customers Say

*AI-generated insights from customer reviews*

Owners of the Maxim Defense PDX in 7.62x39mm tend to be enthusiastic but specific about what they like and don't like. The compact dimensions get consistent praise from people using it for home defense and tactical training, where working in tight spaces matters. Build quality comes up often. The materials feel solid and the tolerances are tight, which builds confidence in the platform.

Performance and accuracy are generally well-regarded for a 5.5-inch barrel, and most users find recoil manageable. The adjustable brace and controls get positive marks for ergonomics during longer sessions. Price is a real point of debate: some owners think the feature set justifies the cost, others find it hard to reconcile with similar-performing options at lower price points.

Feeding issues with certain ammunition types show up in a minority of reports, usually during the initial break-in period. The standard advice from the community is to run a variety of loads before trusting it for defense. Aesthetics are generally liked for the modern tactical look, though that's personal preference.
