NO they arent not even close
It is CLOSE.
The only criteria a SBR does not fit is the Intermediate caliber ammo.
The collapsable stock HK33 and AK74U shorty(krink), Sig Rattler. FN even makes the SCAR shorty listed as a PDW. These are all stated by the manufacturer as a PDW.
Soooo, a 5.56 SBR with super short barrel and collapsable/folding stock DOES fit the definition of a PDW as a COMPACT, MAGAZINE FED, AUTOMATIC FIREARM designed to bridge the gap between a standard handgun and a full-sized service rifle.
Definition
Military Definition of a Personal Defense Weapon (PDW)
In military terms, a
Personal Defense Weapon (PDW) is a
compact, magazine‑fed automatic firearm designed to bridge the gap between a standard handgun and a full‑sized service rifle. It is intended for
secondary defensive use by personnel who are not primary combat troops but may still be at risk of close‑quarters encounters with hostile forces
Wikipedia+1.
Core Characteristics
- Compact size: Short enough to carry in vehicles, tight spaces, or on the person without hindering normal duties Wikipedia+1.
- Automatic fire capability: Most military PDWs are select‑fire (semi‑automatic, fully automatic, or burst), allowing rapid engagement in close combat legalclarity.org+1.
- Intermediate‑caliber ammunition: Fires proprietary small‑caliber, high‑velocity bottleneck cartridges (e.g., 5.7×28 mm FN, 4.6×30 mm HK) that offer better range, accuracy, and armor penetration than pistol‑caliber rounds, but less recoil than full‑power rifle cartridges Wikipedia+1.
- High magazine capacity: Often 20–50 rounds, enabling sustained fire in defensive scenarios legalclarity.org.
- Role: Issued to rear‑echelon or support personnel such as engineers, drivers, medics, artillery crews, and communications specialists who need more firepower than a handgun but don’t require the bulk of a carbine Wikipedia+2.
Origins and Purpose
The concept emerged from the need to arm
“second‑line” soldiers — those not expected to engage the enemy directly — with a weapon that could handle close‑quarters threats beyond handgun capability. Early examples include WWI machine pistols with stocks and WWII M1 carbines, but modern PDWs evolved in the late 1980s/1990s to meet NATO and U.S. Army requirements for compact, selective‑fire weapons

Examples
- FN P90 – 5.7×28 mm, 50‑round top‑feeding magazine, widely used by military and police Wikipedia+1.
- Heckler & Koch MP7 – 4.6×30 mm, 20–40‑round box magazine, used by U.S. military and NATO forces legalclarity.org+1.
In summary: Militarily, a PDW is a
compact, automatic‑firing, intermediate‑caliber weapon designed for close‑defense scenarios by non‑frontline troops, balancing portability, firepower, and effectiveness
