Title: Lug for a sling swivel question
Post by: Cory Joe Stewart on September 14, 2019, 09:06:55 PM

Hello everyone.  I have always used four lugs on rifle barrels.  I am building one now that I will use a sling swivel on.  Here is my question, does the lug for the swivel count as one of the four lugs to hold the barrel on? Or do I need to install four in addition to the lug for the sling swivel?

Thanks

I'm certainly no authority on such things but I put a lug on my smoothbore specifically for the swivel.  The gun only had three lugs to begin with so installing a 4th lug gave me the chance to locate it so that the swivel wouldn't damage the stock - when it swiveled back and forth it only contacted a rod ferrule.

When I have added a sling swivel I always attached it to a separate lug.  My sling lugs are always wider then a barrel tenon and they are placed in front of a ramrod pipe so when the the rifle is standing upright, the swivel does not interfere with installation of the ramrod.

Ok. Didnt think about the idea of placing it near a ramrod. Thanks!

I do the same as Dave, but if it coincidently ends up where a barrel pin would be located you could just make the swivel lug a little longer.

The Long Land Pattern Brown Bess, or 1st model, used one of the barrel tenons to double as a sling swivel.  But it is a heavy duty affair with a substantial seat soldered to the barrel.  Do do rely on the stock wood to support the swivel.

Hi Taylor,
That was true only for the early pattern 1730 muskets.  It was abandoned on all later long land pattern Besses.

Ah, I built a copy of the 1728, and it called for those special lugs.  I used my old small mill to create the lugs...see may have a couple.

When I make a lug for sling swivels it is the full width of the barrel flat, shaped like a bridge trestle. This way the swivel axle cannot waggle enough to split the forend if the clearance hole in the stock is generous enough. I size the hole in the lug so the swivel screw is just a free fit with as little wobble as possible. 1/2 inch key stock is usually perfect raw material. BJH
