  • PROOF Research Terminus Actions Stainless Steel Pre-fit Barrels

Fans of Terminus actions will be an even bigger fan of the PROOF Research prefit stainless steel designed for the Zeus and Apollo action. PROOF's Terminus prefit barrels will arrive threaded/chambered with 5/8x24 muzzle threads. This is a shouldered barrel that requires few specialized tools for install. They're offered with a variety of caliber, lengths, and twist rates in stainless steel..

* These Terminus prefit barrels are pre-headspaced. However, it is always recommend to double check headspacing with proper gauges before firing a rifle.

    Screwed this on my new Terminus Apollo action @ 85ft lbs and was off and running. Only have about 90 through it so far and it has steadily gained velocity. Many groups in the .3's and nothing over .7's so far. Just as accurate as my Bartlein chambered by a very well known smith. Barrel contour is a beast but balances well in my XLR Envy pro with stock gap weights. I bought another in 6mm creedmoor and another Apollo. Excellent action and barrel combo.
