When I discovered that my Elbit Falcon MkII optical sight was incompatible with the M4 handguard I had on my IDF Colt Commando clone build, I decided that it would be easiest to simply buy a new CAR-15-style handguard. As this is a blog devoted to Israeli small arms and accessories, my first thought was “let’s see how the FAB Defense handguard works”. It was cheap-ish (about $25), and I liked the idea of using a handguard that an IDF soldier might think of replacing a broken handguard with. So, I bought one.
The FAB Defense HG-S carbine-length handguard is well-constructed, and has top and bottom heat shields. It looks remarkably similar to a USGI CAR-15 handguard, Unfortunately, and this will be the shortest review I’ve ever done on this blog, they didn’t actually fit on my gun. The total length of the handguard was too long, and the delta ring simply would not slide down far enough to accommodate it. Keep in mind, the upper on this gun is a genuine Colt LE6933 upper which has never had handguard fitment issues before (M4, CAR-15, Magpul MOE, etc.). I could theoretically have sanded the handguard ends down to make it fit, but bluntly, this is not acceptable as a solution. So, here’s my review: don’t buy the FAB Defense HG-S. It looks nice, but will probably have trouble fitting in-spec AR-15s.
