A cautionary tale for those using the chamber plug.
I would advise that you do a leak test with the chamber plug if you plan on using nasty solvents that may hurt your action/coating.
I bought a .308 PVA chamber plug to deep clean my TacOps barrel with CLR. I put in the chamber plug and put CLR down the bore. I checked initially and didn't see any leaks. I let the CLR soak for about ~10-12 hours, and came back to see the bolt was wet and there was a very small puddle below the action. Took out the chamber plug and discovered it developed a slow leak, and the Birdsong finish of my action started to strip on the raceways, the underside of the bolt, and the bolt lugs. I have to now send the rifle off to TacOps to get completely re-done. Action, barrel and DBM all need to be re-done with Birdsong to ensure they match. A costly mistake that I now have to deal with.
In defense of
@bohem/PVA, it does not state on their site that this product will work with CLR. I somehow made this assumption and didn't even think to check with PVA if this product would work with CLR. I don't know if my issue was a case of the plug not working properly, or if there's an incompatibility with chemicals such as CLR. I just made the assumption that it would seal the chamber and life would be good.
In hindsight I feel like a dumbass for even attempting this. I'm telling others this story so they don't make the same mistake. I'll give PVA the benefit of the doubt that this product works for other solvents. But don't assume if you are using anything that can cause any damage to your action and coating. Test first and/or contact PVA for chemical compatibility with the seal.
