...yes...I took basic from Jun - Aug '71 at Ft Dix (A-3-3) - most armorers had no idea what they were - my late brother, Ray, a lefty, got a a nasty burn on his chest from a hot case Ft Dix a year later, different company/battalion...the armorer had the deflectors but didn't know what they were or how to use 'em...BTW - my M16in basic was an H&R also...
