From the manufacturer
RE5F is a 9 position 308 AR compatible receiver extension (RE), it is also 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 FCD 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 Mfg: Forward Controls Design
