Rimfire AR-15 rifles are nothing new, but they all use a blowback based operating system. This puts tons of stress on the cases, and for some of the more powerful rimfire cartridges it can rupture the cases as they’re being extracted from the gun. Franklin Armory wanted to make a semi-automatic rifle in .17 Winchester Super Magnum, and so they completely redesigned the internal components of an AR-15 to function with the cartridge. Now cases extract under lower pressure, the gun cycles reliably, and you can use all standard AR-15 components for stocks and triggers. Naturally, we’ll test one out and get back to you.
Oh, and its pretty. MSRP is gunna run about $1,799, but for serious varmint hunters accept no substitute.
