Description
Aim7 Nielsen Booster Assembly Stainless Steel with Piston (1.375×24 HUB Bravo)
The Aim7 Nielsen Booster Assembly with Piston is a precision-machined recoil booster (linear decoupler) engineered to replace direct-thread adapters on standard 1.375×24 (1-3/8×24) HUB Bravo-pattern platforms. Designed specifically for Browning-type tilting barrel handguns, this booster system allows reliable, uninhibited cycling by temporarily decoupling suppressor mass during the firing cycle.
Featuring an H900 heat-treated 17-4 stainless steel housing, a Swiss CNC-machined 17-4 stainless piston, and a hardcoat anodized 6061-T6 aluminum retainer nut, this complete kit provides seamless adaptability across multiple host thread pitches and popular modular setups.
Key Features & Performance
- Reliable Semi-Auto Cycling: Inertial decoupling mechanism ensures consistent, flawless slide cycling on tilt-barrel handguns without inducing short-stroking or feed failures.
- H900 Heat-Treated 17-4 Stainless Housing: CNC-machined from solid 17-4 PH stainless steel for extreme structural resilience against repeated concussive chamber blast.
- Complete with Piston: Includes a Swiss CNC-machined 17-4 stainless steel piston treated in a QPQ black nitride finish for smooth slide travel and superior wear resistance.
- Universal 1.375×24 HUB Standard: External 1-3/8×24 Bravo thread pitch allows direct integration into standard 1.5″ OD modular tubes and Bravo-pattern housings.
- Tactical Matte Black Finish: High-grade black nitride and hardcoat protective treatments eliminate glare while sealing components against corrosive carbon buildup and moisture.
