PSA Sabre AR-V 9mm

The PSA Sabre AR-V replaces the base AR-V's direct-blowback action with a Maxim Defense roller-delayed blowback (RDB) system, PSA's headline upgrade for the Sabre tier. The rollers meter bolt unlock timing off recoil impulse rather than raw bolt mass, which softens felt recoil and speeds up sight tracking between shots compared to the straight-blowback base AR-V.

Sabre-specific parts carry the rest of the package: a hard chrome-coated bolt carrier group, Radian Raptor LT charging handle, Radian Talon ambidextrous safety, a SABREclaw two-stage trigger, and a SABRE QDSM free-float handguard. The 8-inch nitrided 4150V chrome-moly barrel ships 1/2x28 threaded with an SBA4 pistol brace in RAL 8000 finish. It keeps the AR-V's magazine interface, so PSA U9 and CZ Scorpion-pattern magazines still drop in.

The RDB system runs on close-tolerance rollers and ball bearings, and PSA has publicly noted the charging handle can feel stiffer than a direct-blowback gun out of the box before it breaks in over a few range trips. This is a new product line (launched mid-2025) with limited independent long-term reliability data; as of this writing it was listed only on PSA's own site, so verify current availability and retailer options before buying.
