Here's "The Plug"
Simple: Over the past decade of making rifle barrels we have seen a sharp uptick in two things with the precision rifle world.
1) People don't clean barrels (the reasons are varied but mostly it comes down to the fact that cleaning sucks)
2) People who do clean have a tendency to damage barrels through scrubbing.
3) Sometimes shooters don't want to take off their muzzle device to use a PVA Muzzle Jimmy.
Modern rifle powders are every increasing in performance and complexity. Long Range bullets are constantly getting longer and going faster. The powder and bullet combinations are starting to show the trend of carbon fouling rings and the premature death of precision rifle barrels (check out the PVA Osprey Barrel Works blanks if you want something with better, longer lasting stainless steel).
Cleaning is important and minimizing the mechanical wear that comes from scrubbing a carbon-fouled patch through that precious chamber throat is critical. This is why we brought out the Muzzle Jimmy to allow soaking the barrels for more extended time and to create the situation where the cleaning solvent is not the limiting reagent in a barrel. This means easier, faster cleaning with less scrubbing and less chance of damage to the crown and the throat.
Cleaning operations use a cleaning SOLVENT, which to be a solvent must be the chemical in excess during the solution process. This means that the old method of soaking patches, wiping them through the bore with a solvent on them and hoping enough gets into the bore to react with the baked in fouling is akin to making steel via blacksmithing. The solute, which is the fouling, needs to be the Limiting Reagent in the chemical reaction. Meaning that the chemical being dissolved must be the thing that stops the reaction when there is no more if it left. If the solvent (like your Hoppes or BoreTech or Montana Extreme or whatever you want to use) is the limiting reagent then the cleaning only continues until there isn't any more solvent left and the excess chemical remaining is the fouling.
So... make the excess chemical in the reaction the solvent and your life with a bore rod and patch becomes totally different. There's the solution for that, the Muzzle Jimmy.
What about barrels that have a specific muzzle device that's not easy to remove or no muzzle threads? Now we have "The Plug"
The same high resistance, viton rubber seal material is used and we have consecutive days of leak down test data with solvents like acetone, isopropyl alcohol and MEK. Now you can insert The Plug, drop in the Jimmy Stick, and fill up the bore. Come back tomorrow and wipe out the nastiness carbon and copper fouling with ease.
The Plug is made from anodized aluminum (initial photos are from test prototypes without anodizing). CAUTION: Do not use CLR as a solvent. It has been known to eat aluminum and will destroy the Plug as well as eat up pieces of the rifle.
The Plug is chamber body specific. It is not bore specific within the family. IE you can use it for a 243, 260, 7-08, 308, 338 Federal and 358 Winchester with the same Plug. Likewise you can use one for the 22, 6, 25, 6.5, 7 and 338 Creedmoor all with the same Plug.
Initial sizes are listed above with more coming each month.
How about some cheesy testimonials?

Clearly there's some tongue-in-cheek here for a laugh. The point is that this little widget makes your life easier when taking care of the precision rifle that you've invested so much money into.
