RE5F is a 9 position 308 AR compatible receiver extension (RE), it
is also compatible with Vltor's splendid A5. REF5 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 / REF5 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).
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.
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.
