SRX3 – Stribog Receiver Extension – 3″ Black


In stock


Designed to fit the Stribog SP9 models with M-Lok receivers. The SRX was developed with the same mindset as our MREX rail lineup. Made from strong 6061-T6 aluminum, this durable receiver extension was built for comfort and ergonomics. The added 3 – 6 inches gives you an enhanced grip further down the Stribog while providing plenty of real estate for added accessories. The SRX was also designed around the option of adding a variety of suppressors, with plenty of ventilation to ensure a comfortable, cool grip even after extended suppressor use.
