While the standard Rhodesian Army rifle was the FAL, their next most common rifle was the G3. These were mostly of Portugueses origin, and had the thing and narrow style of G3 handguards. In an effort to counteract the rapid heating of these handguards, a domestically designed and produced clamp-on insulator was made. Molded from resin, they are relatively fragile and were not made in large numbers.

Thanks to Bear Arms in Scottsdale AZ for loaning me use of their G3 and FAL for the video!
