Our forward pipe, with lug for pin, is 1" overall length. Made for a fullstock rifle (with wood extending to muzzle), most pistols use one, rifles use two forward pipes. A few extra long rifles use three forward pipes. Use one, or sometimes two #PIN-3/32 steel dowel pins, to retain a brass pipe.

Fullstock rifles, with wood to the muzzle, require one entry pipe, and two forward pipes with pin lugs. Order three mounting pins. Extra long fullstock rifles may use three forward pipes.
