Thread: DPT Suppressor seized up

Allan Carr who l rate up there with gun smiths work l have seen any where in the world,did a lot of my rifle builds & he always said never to use any tape on the threads, only a lithium grease & the internals should be cleaned regularly with a good water/moisture dispersal spray like WD40 was all thats required ,the reason he said is suppressors suck in a lot of moisture especially if used with a cover & that moisture in turn soaks up the ammonia in the gun powder.This then acts as means for more corrosive elements to build up over time & around the rifle crown/rifling ,he always recommended a thorough clean after 40 rounds max for a short barrel hunting rifle (he did most of my Bush Pig builds)& the suppressor left off the rifles in storage with good air flow & a coating of WD40.

The last time l brought a DPT over barrel from memory it came with a sheet warning if tape was used on threads or excessive build up was found it would void any warranty.

While l was guiding in the US one of the clients had a huge gun collection & would have a machine gun shoot on his Ranch twice a month during summer ,guys would turn up with everything imaginable & a lot were suppressed, they all used high temp Locktite anti seize on all threads .

I use to race Dirt Bikes so still have a lot of tools for rebuilds etc & have helped a couple of mates over the years free up stuck baffles which would happen particularly after our regular hunting /diving trips to Stewart Island, where guns would cop salt spray for a couple of weeks in the sand dunes etc & from travelling around in the big boat & dinghy,always found a small bike oil filter wrench with a wrap of leather worked ,for really stuck ones put it in a oven to warm up first,always freed them straight up .
