Description
The 22 ARC has been turning heads since Hornady rolled it out, and this Thompson Center Encore Prohunter barrel gives you an easy way to add that cartridge to a platform you already own. Swap the hinge pin, pull two forend screws, and you have gone from whatever you were shooting to a flat-shooting 22 caliber setup built around high BC bullets. That is the whole appeal of the Encore system, one frame and a stack of barrels covering everything from deer rifles to shotguns to muzzleloaders.
What The Encore Prohunter 22 ARC Barrel Brings To The Table
This barrel measures 26 inches, finished in stainless steel with fluting cut down the length of it to shave weight without giving up the stiffness a heavy contour barrel is known for. The 22 ARC cartridge was designed around modern, high ballistic coefficient bullets, giving you 22-250 level performance with better wind resistance and typically longer barrel life. Loaded with 62 grain bullets you are looking at velocities around 3300 fps, while the heavier 75 and 88 grain options trade a bit of speed for even flatter long range trajectories.
Fluted Stainless Build Ready For Your Optic
Like other Encore rifle barrels, this one ships with no sights since it is drilled and tapped for a scope base, so you can mount your glass and forget about it since sight-in stays consistent even after swapping barrels down the road. The muzzle is threaded 1/2-28, ready for a brake or suppressor if that is part of your setup, and comes with a thread protector to keep those threads clean when you are not running anything on the end. Button rifled construction and a honed bore are standard across the Encore rifle lineup, which is part of why these barrels have a reputation for shooting tighter groups than you would expect from a break action gun.
Where This Barrel Really Shines
Whether you are chasing coyotes across open country, thinning out a prairie dog town, or just want a flat shooting round for target work, the 22 ARC gives you a lot of capability without beating up your shoulder. Keep in mind this barrel is built for the Encore rifle frame and forend, not the pistol frame, so make sure your setup matches before ordering. Once it is on your frame you are looking at a genuinely versatile little rifle that can hunt varmints one weekend and get swapped for a big game barrel the next.

Frequently Asked Questions
Will this Encore Prohunter barrel fit my existing Encore frame?
Yes, Encore and Encore Prohunter barrels are built to be interchangeable across any Encore frame. You will need the rifle forend rather than the pistol forend since this barrel uses the heavy rifle contour, but the swap itself just takes removing the hinge pin and forend screws.
Does this barrel come with a scope base or mount?
No, it ships without sights or a scope base since it is drilled and tapped so you can add whatever base and optic setup you prefer. This keeps the barrel flexible for whatever scope or mount you already have on hand.
What can I expect from the 22 ARC cartridge out of this barrel?
The 22 ARC was built around high BC bullets to give you 22-250 style performance with better wind bucking ability and typically longer barrel life. It shines on varmints and predators, and heavier bullet options in the 75 to 88 grain range extend that flat shooting performance well past 300 yards.
Can I run a suppressor or muzzle brake on this barrel?
Yes, the muzzle is threaded 1/2-28 and comes with a thread protector installed for when you are not running anything on the end. That makes it simple to add a brake to tame recoil or thread on a suppressor if that fits your setup.
