I went pick up my 300 BLK barrel from Templar Custom this afternoon, and while there Bob Reynolds showed me a cool single-shot all-metal .22 Magnum takedown he’d picked up. He’d not seen anything like it before, and I hadn’t either.
I found the picture above in an old auction. Piecing together comments from various forums, is called a Bronco and originally came from a company either called FI or FIE that some seemed to think was a CIA front company. When FI/FIE went under, the Garcia version (Garcia the fishing gear company?) came out in 1971 or there about for $15.95. It was designed as a competitor of the AR-7 survival rifle. The metal described as an ordnance steel barrel with either a zinc pot metal or aluminum frame. The balance was good, and the single shot trigger quite serviceable.
It seems to be a clever design, and seems to be something of a niche collector’s item. If someone made a modern version of these today for $100-$150 or so, I think I’d be tempted to buy one.
