Description

Knights Armament Company Titusville M4 RAS quad rail assembly. These are SURPLUS.

 

Screws may or may not be included.

 

The KAC M4 RAS (Rail Adapter System) was developed for use on the US military’s M4 Carbine, and with over 1 million rails issued to date, it is one of the most battle proven designs available for the AR-15 platform. This non-free float handguard is a simple-to-install, drop-in upgrade that features genuine Mil-Spec M1913 Picatinny Rails along its entire length.

Rifle Requirements: The M4 RAS is a drop-in replacement part for standard, 2-piece polymer, M4-type handguards. The rifle must have a carbine length gas system, delta ring assembly, fixed front sight/gas block, and round handguard end cap. Lighter barrel profiles work best (M4 or Government contours). Heavier barrel contours may require modification to the inside of the rail

    Don't Hesitate

    I usually don't write reviews, but I wanted to drop this in case you're on the fence (like I was) about purchasing this surplus KAC M4 RAS QUAD RAIL. The rail I received had all the hardware, I had no problem installing it, and the lock up is solid. This YouTube video helped me with the install: https://www.youtube.com/watch?v=YFYTAjIKgkA. It definitely has some wear, but I don't think it's as bad as the product images above. This is the first time I've ordered from Wet Worx Outfitters and they shipped it out fast. Apparently, these rails are hard to come by and I'm glad I decided to make this purchase.

    Very nice

    Was looking for a legit KAC RAS for my Mod 0 build. Wet Worx was one of the few that still had it in stock at a similar/competitive price point. Expensive, but quality doesn't come cheap. Rail was in very good condition, locked up solid, and just looks great! Wet Worx also had very quick shipping and outstanding service! I highly recommend them!

    Great looking surplus rail. The dings and scratches were perfect for the rifle it was going on. Lockup is second to none.

    M4 RAS

    Rail came in excellent condition with all parts accounted for. There was some extremely sticky adhesive on all side but was an easy cleanup. Another great shopping experience with Wetworx
