Will the GrovTec GTSW84 swivel set fit my Thompson/Center Renegade if I have upgraded to a Green Mountain aftermarket barrel?

No, the manufacturer explicitly states that this model will not fit Green Mountain aftermarket barrels due to differing ferrule spacing and dimensions. It is engineered specifically for factory ramrod dimensions on Thompson/Center Renegade and New Englander models.

What size carrying sling should I buy to pair with the 1-inch loops on the GTSW84 set?

You must use a sling with a maximum webbing width of 1.0 inch, as the loops are strictly sized for this dimension. Tactical or heavy padded slings using 1.25-inch straps will not fit through these loops.

How does the locking mechanism on these swivels perform during rough outback hunts in heavy Australian bush?

The swivels utilise GrovTec's positive locking mechanism equipped with a knurled threaded collar or sleeve. This design actively prevents accidental gate opening when your rifle brushes against dense scrub and thick branches while trekking through the bush.

Muzzleloader Swivel Set - GrovTec GTSW84

The GrovTec Muzzleloader Locking Swivel Set (GTSW84) provides a dedicated hardware solution for attaching a carrying sling to traditional Thompson/Center side-lock muzzleloaders. Engineered specifically for the T/C Renegade and New Englander platforms, the kit replaces the factory forward ramrod ferrule with an integrated swivel stud, eliminating the need to drill into thin forend wood or clamp external brackets around the barrel. Constructed from all-steel components with a corrosion-resistant black-oxide finish, it includes a matching rear wood-screw buttstock stud and a pair of 1.0-inch (25.4 mm) locking quick-detach swivels.

Key Features

Integrated Ferrule Replacement: Installs a direct replacement front ramrod ferrule featuring an integrated sling stud to preserve factory ramrod function and traditional aesthetics.
Positive Locking Swivels: Features knurled threaded locking collars that secure the swivel gates against accidental opening when moving through dense bush.
All-Steel Construction: Built entirely from steel treated with a black-oxide finish for field durability and resistance to corrosion.
Complete Hardware Kit: Includes the replacement front ferrule stud, a standard rear buttstock wood-screw stud, and two 1.0-inch quick-detach locking swivels.

Who is the Grovtec T/C Renegade, New Englander Swivel Set 1" Loops for?

Thompson Center Renegade muzzleloader hunters — requires a hands-free field carry setup that attaches standard 1.0 inch (25.4 mm) sling webbing to factory hardware while adding just 0.18 lbs of hardware to the rifle.
Thompson Center New Englander black powder target shooters — needs a secure muzzleloader sling swivel set that preserves the original ramrod channel and handles standard 1.0 inch wide target slings without drilling into the forend stock.

Less suitable for: Shooters using Green Mountain aftermarket barrels or slings wider than 1.0 inch (such as 1.25-inch tactical webbing), who require larger 1-1/4" loop swivel sets or dedicated aftermarket barrel-band mounting hardware.
