Bifurcated Lumps

Bifurcated Lumps

Bites
Bifurcated Lumps - A locking system for over & under guns whereby the barrels are fitted with semi-circular hooks that hinge around trunnions on either side of the lower barrel. A pair of bolts move forward into recesses on either side of the barrel-set when the gun is closed. This system makes it possible to build an over & under gun with a sleeker, lower profile than possible when mounting the lumps, hook, and locking bites to the underside of the bottom barrel. Boss and Woodward guns are built with bifurcated lumps.
_________________________________________

Browning and Merkel guns are built with lumps under the barrels and with the hook revolving around a traditional hingepin, as on the Merkel above with double Purdey underbites. While strong, this design results in a gun with a taller profile than does the bifurcated lump design.
