Description
If you already own a Thompson/Center Encore or ProHunter pistol frame, this barrel is one of the easiest ways to add a new caliber without buying a whole new gun. Chambered in .300 AAC Blackout and cut to 15 inches, it drops right onto your existing frame so you can go from your current setup to a Blackout pistol in the time it takes to swap a barrel. The stainless steel construction resists corrosion out in the field, and the fluting cuts down on weight without sacrificing the barrel's stiffness or heat handling.
ProHunter Barrel Details Worth Knowing
This 8102R barrel carries a 1-in-8 twist rate, which gives you enough flexibility to run lighter supersonic .300 Blackout loads as well as heavier subsonic bullets if you're planning to run it suppressed. The muzzle comes threaded 5/8×24, so pairing it with a suppressor or muzzle device is straightforward. There are no sights included on this barrel, but it's drilled and tapped for a standard T/C four hole scope base if you want to mount an optic down the road.
Fitting This Pistol Barrel to Your Frame
Keep in mind that this is a barrel only, so it will need to be paired with a compatible Encore or ProHunter pistol frame that you already have on hand, along with a forend that matches the pistol barrel contour. T/C pistol barrels use their own contour that's different from the rifle barrels, so double check your forend fits before you order if you're not running the factory setup. Once it's mounted up, you get the same reliable single shot break open action T/C has built its reputation on for decades.
Why the .300 Blackout ProHunter Barrel Makes Sense
A .300 Blackout pistol barrel gives you a short, maneuverable option that still hits with plenty of authority at the ranges most hog and deer hunters are working with, and the threaded muzzle means it plays nice with a suppressor for a quieter, softer shooting experience. It's a straightforward way to stretch the versatility of a platform that was designed from the ground up to be modular.

Frequently Asked Questions
Will this ProHunter barrel fit my Encore pistol frame?
Yes, this 8102R barrel is built for the Encore and ProHunter pistol frames and swaps on without any gunsmithing. Just make sure your forend matches the pistol barrel contour, since ProHunter pistol barrels use a different profile than the rifle barrels.
Does the .300 Blackout ProHunter barrel come with sights or a forend?
No, this is a barrel-only item with no sights included, though it is drilled and tapped for a standard T/C four hole scope base. The forend and grip are part of the pistol frame assembly and aren't included with the barrel.
Can I run a suppressor on this barrel?
Yes, the muzzle is threaded 5/8×24, which is a common thread pattern for .300 Blackout suppressors. It ships with a thread protector to keep the threads clean when you're not running a can.
What twist rate does this .300 Blackout barrel use and does it matter for ammo choice?
It's cut with a 1-in-8 twist, which stabilizes both lighter supersonic bullets and heavier subsonic loads reasonably well. That flexibility is one of the reasons the 1-in-8 twist has become a common standard for .300 Blackout barrels.
