GSL Bi-Lock Flash Hider for P90 / PS90
The GSL P90 Flash Hider delivers the classic factory P90 appearance with modern suppressor-ready performance. Designed for the 10.4" short barrel, this flash hider replicates the look of the original P90 while integrating GSL’s proprietary bi-lock quick attach system for fast, secure suppressor mounting.
Traditional suppressor setups required a thread adapter followed by a separate flash hider or suppressor mount. This stacked approach added length and complexity. The GSL Bi-Lock Flash Hider simplifies your build by replacing both components with a single, direct-mount solution—reducing tolerance stacking, improving alignment, and preserving proper barrel float operation in your PS90 SBR or XF50 configuration.
Key Features:
- Factory-Style Profile: Mimics the original P90 flash hider for an authentic look
- Integrated Bi-Lock Mount: Compatible with all GSL bi-lock suppressors, including the GSL P90 suppressor and other GSL models rated for 5.7x28mm and above
- One-Piece Solution: Eliminates the need for a separate 1/2" x 28 thread adapter and mount
- Reduced Tolerance Stacking: Improves suppressor alignment and reliability
- Maintains Floating Barrel Design: Ensures proper operation of the delayed-blowback system
- For Use with 10.4" Barrel Only: Not compatible with factory 16" PS90 barrels
- Precision Machined in the USA by GSL Technology
