Our forward pipe, with swivel lug, is 1-5/32" overall length. As cast to accept a 7/16" diameter ramrod. Made for a fullstock gun (with wood extending to muzzle), use a single pipe to replace a forward pipe, and add a swivel lug to your rifle project. A few extra long guns use three forward pipes. Use one, or sometimes two #PIN-3/32 steel dowel pins to retain.
