RE5F Receiver Extension A5
NOTE:
RE5Fs are made from impact extrusion 7075, and can have minor marks and imperfections from the manufacturing process, these miniscule imperfections don't affect function and are covered once the stock is installed. Cerakote can cover these imperfections most of the time, they may be slightly more visible on anodized RE5Fs.
Mid 2026 RE5F has a slightly different design, starting with black anodized, there will be anodized FDE and ODG options, along side Cerakoted FDE and ODG. All RE5Fs will be brought to the new design in 2026, it's available on anodized black first.
1. Additional drain hole behind the threads
2. Lengthened bottom rail
RE5F is a 9 position receiver extension compatible with Vltor's splendid A5. RE5F is a collaboration with SOLGW, and is identical to Sons of Liberty Gunworks Loyal 9 A5 RE save for the respective company logo/name engravings. Forward Controls had contributed design input (extra drain holes and softening of sharp corners), there was nothing else we deemed a receiver extension could do better or needed to be improved on, so Loyal 9 / RE5F may look like other REs but with ergonomics and sensible changes, they're made for work, not for show.
RE5F is compatible with 308 ARs and Vltor's A5 system. For AR15/M16 applications, it must use Vltor A5 or A5 compatible buffers, rifle length recoil springs (Vltor's A5 spring or Sprinco's Green spring).
RE5F is made from impact extruded 7075 aluminum with rolled threads. The interior is dry film lubed, the body diameter is milspec (compatible with all milspec carbine stocks), it has extra drain holes to better and more quickly drain water inside the RE.
Weight: 4.24oz
Material: 7075 aluminum
Made in USA
NOTE: For use on AR15/M16, RE5F requires a Vltor A5 buffer, rifle length / A5 / Sprinco Green recoil spring. RE5F is incompatible with standard TDP spec buffers and carbine buffers.
