Description
If you've made the switch to Blackhorn 209 or another loose powder and noticed your ignition getting sluggish or your flash-hole clogging up, this is the piece that fixes it. The CVA Blackhorn QR Breech Plug is a stainless steel replacement designed around the finer, dirtier-burning loose propellants, with a hollowed-out flash channel that lets powder granules settle right up against the 209 primer for a cleaner, quicker light-off. The standard plug that ships with your rifle has a long, pin-narrow flash-hole that struggles to ignite loose powder evenly and tends to plug up, which means constant picking between shots. This plug was built to solve that.
What the Blackhorn QR Breech Plug Actually Does for You
Real-world feedback backs up the design. Folks running Blackhorn 209 with this plug report groups tightening up noticeably and ignition going from an occasional perceptible lag to near-instant. It handles whatever propellant format you prefer, loose or pelletized, so you're not locked into one style. The flash-hole stays debris-free through repeated shots, meaning less time hunched over the breech with a pick and more time on target.
Fitting Your CVA Accura, Optima or Wolf
This is a quick-release plug, but it does need a one-time fitting to your barrel using CVA's QRBP installation tool. You tighten it firmly to seat the threads, snug it past hand-tight, then back it off. After that initial fit, it's completely tool-free to install and remove, so breaking the gun down for cleaning takes seconds. If your hammer won't cock after fitting, the plug just needs to be seated a touch tighter.
Fitment Notes Before You Order
This plug works with CVA Accura V2, Optima, and Wolf models made in 2010 or later, and it also fits Bergara and Thompson/Center Encore 4006 and 4007 barrels. It will not work on the CVA Apex, and it won't fit any rifle that wasn't originally designed for the QRBP system. Stainless construction holds up well against the corrosive nature of black powder residue, and regular flash-hole cleaning keeps ignition sharp season after season.

Frequently Asked Questions
Do I need a special tool to install the Blackhorn QR breech plug?
Yes, for the initial fitting you'll need CVA's QRBP installation tool to seat the threads to your barrel. You tighten it firmly, snug it past hand-tight, then loosen it. After that one-time fitting, no tools are needed to install or remove the plug, which makes cleaning quick and easy. Note that the tool is not always included, so check that you have one before installing.
Will this breech plug fit my CVA muzzleloader?
It fits CVA Accura V2, Optima, and Wolf models made in 2010 or newer, and it also works with Bergara and Thompson/Center Encore 4006 and 4007 barrels. It will not work on the CVA Apex or on any rifle that wasn't originally designed for the QRBP system. If you're unsure of your model year, check the last two digits of your serial number or your rifle's paperwork.
Can I use Blackhorn 209 without buying this plug?
You can run Blackhorn 209 through the standard QRBP that came with your rifle, but the narrow flash-hole tends to clog and ignition can be inconsistent, so you'll be cleaning between nearly every shot. This Blackhorn plug has a hollowed flash channel that lets loose powder settle closer to the primer for faster, more reliable ignition. Most people who switch see tighter groups and fewer ignition hiccups.
Does it work with pellets too, or only loose powder?
It handles both loose powder and pelletized propellants, so you're free to load however you prefer. It's optimized for finer loose powders like Blackhorn 209, where the flash channel design really shines. Either way, keeping the flash-hole clean is the key to consistent ignition.
