Forward Controls Design REF Buffer Tube

REF (Receiver Extension, carbine, FCD) is a 6 position, AR15/M4 standard carbine receiver extension (NOT A5 compatible).  Made from impact extruded 7075 aluminum with rolled threads and dry film lubed interior, REF differs from most carbine receiver extensions thusly:

* Additional drain holes in the 2nd and 5th latch positions, in addition to the TDP spec carbine RE drain hole at the end of the RE.

* Laser engraved stock latch position indicators on both sides.

* Cerakoted.

We’re not known for making modifications to TDP spec components just to be different.  Different is just that, different isn’t better.  REF follows our design philosophy, function over form, form follows function.  The changes on REF are for the most part not immediately visible to users.

Colt M4 stocks have an open portion on top the butt pad, TDP spec carbine RE has a drain hole at the end/tip to allow water to drain.  The M4 stock can trace its origin to the early 1980s ACR trials, though they ended without any being adopted to replace the M16, inevitably some developments led to designs later incorporated into production systems, one of which is the now ubiquitous M4 stocks made by Colt, and later, SOPMOD stocks made by Crane at NSWC, LMT and B5 Systems.  Stocks with superior cheek weld and storage made by industry giants Vltor and Magpul have long led the way in ergonomics and practicality.

Proudly made in the USA.
