Stribog handgaurd by EB, Verified Owner, July 30, 2024
This hand guard is extremely well built and fits tight to the upper receiver with zero slop. Install is a little tricky but takes less than 10 minutes. 9+45 suppressors fit with zero issue.

Product Info for Kinetic Development Group SRX6 Stribog 6in Receiver Extension

Introducing the SRX6 for the Grand Power Stribog. Designed to fit the Stribog SP9 models with M-Lok receivers. The SRX6 was designed with the same mindset as our MREX rail lineup. Made from strong 6061-T6 aluminum, this durable rail extension was built for comfort and ergonomics. The added 6 inches gives you a more enhanced grip furth down the Stribog while adding plenty of real estate for added accessories. The SRX6 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.image
